Screen saver related fixes.
1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare
loading/unloading of a screen saver. The screen saver calls these
functions to notify syscons of loading/unloading events.
It was possible to load multiple savers each of which will try to
remember the previous saver in a local variable (`old_saver'). The
scheme breaks easily if the user load two savers and unload them in a
wrong order; if the first saver is unloaded first, `old_saver' in the
second saver points to nowhere.
Now only one screen saver is allowed in memory at a time.
Soeren will be looking into this issue again later. syscons is
becoming too heavy. It's time to cut things down, rather than adding
more...
2. Make scrn_timer() to be the primary caller of the screen saver
(*current_saver)(). scintr(), scioctl() and ansi_put() update
`scrn_time_stamp' to indicate that they want to stop the screen saver.
There are three exceptions, however.
One is remove_scrn_saver() which need to stop the current screen saver
if it is running. To guard against scrn_timer() calling the saver during
this operation, `current_saver' is set to `none_saver' early.
The others are sccngetc() and sccncheckc(); they will unblank the
screen too. When the kernel enters DDB (via the hot key or a
break point), the screen saver will be stopped by sccngetc().
However, we have a reentrancy problem here. If the system has been in
the middle of the screen saver...
(The screen saver reentrancy problem has always been with sccnputc()
and sccngetc() in the -current source. So, the new code is doing no
worse, I reckon.)
3. Use `mono_time' rather than `time'.
4. Make set_border() work for EGA and CGA in addition to VGA. Do
nothing for MDA.
Changes to the LKM screen saver modules will follow shortly. YOU NEED
TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES.

Screen saver related fixes.
1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare
loading/unloading of a screen saver. The screen saver calls these
functions to notify syscons of loading/unloading events.
It was possible to load multiple savers each of which will try to
remember the previous saver in a local variable (`old_saver'). The
scheme breaks easily if the user load two savers and unload them in a
wrong order; if the first saver is unloaded first, `old_saver' in the
second saver points to nowhere.
Now only one screen saver is allowed in memory at a time.
Soeren will be looking into this issue again later. syscons is
becoming too heavy. It's time to cut things down, rather than adding
more...
2. Make scrn_timer() to be the primary caller of the screen saver
(*current_saver)(). scintr(), scioctl() and ansi_put() update
`scrn_time_stamp' to indicate that they want to stop the screen saver.
There are three exceptions, however.
One is remove_scrn_saver() which need to stop the current screen saver
if it is running. To guard against scrn_timer() calling the saver during
this operation, `current_saver' is set to `none_saver' early.
The others are sccngetc() and sccncheckc(); they will unblank the
screen too. When the kernel enters DDB (via the hot key or a
break point), the screen saver will be stopped by sccngetc().
However, we have a reentrancy problem here. If the system has been in
the middle of the screen saver...
(The screen saver reentrancy problem has always been with sccnputc()
and sccngetc() in the -current source. So, the new code is doing no
worse, I reckon.)
3. Use `mono_time' rather than `time'.
4. Make set_border() work for EGA and CGA in addition to VGA. Do
nothing for MDA.
Changes to the LKM screen saver modules will follow shortly. YOU NEED
TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES.

Alot of fixes from kazu:
1. All the suggestions earlier made by Bruce: renaming some symbols,
stricter error checking, removing redundant code, etc.
2. The `psm' driver preserves the default counter resolution and
report rate, whatever they are after reset. (Based on reports and
suggestion from Nate and Rob Bolin).
3. The `psm' driver now does not check the so-called sync. bit in the
first byte of the data packet by default, so that the tapping feature
of ALPUS GlidePoint works (based on reports from Louis Mamakos). I
tested the code with ALPUS Desktop GlidePoint (M/N GP101) and found
no problem; tapping worked. It appears ALPUS produces several models
of GlidePoint. I hope the other models are OK too.
The check code can still be activated by defining the PSM_CHECKSYNC
option in the config file. (The bit checking slightly reduces, if not
completely eliminates, weird mouse behavior cased by unsynchronized
mouse data packets. It also helps us to detect if the mouse interrupt
can ever be lost. But, well, if there are devices which cannot be
supported this way...)
4. The `psm' driver does not include the protocol emulation code by
default. The code can still be compiled in if the PSM_EMULATION option
is specified in the config file. Louis Mamakos suggests the emulation
code is putting too much in the kernel, and `moused' works well.
I will think about this later and decide if the entire emulation
code should be removed.
5. And, of course, the fix in `scprobe()' from Bruce to cure the
UserConfig problem. My code in `kbdio.c' is slightly different from
his patch, but has the same effect. There still is a possibility that
`scprobe()' gets confused, if, for whatever reasons, the user holds
down a key for very long time during the boot process. But we cannot
cope with everything, can we?

A fix/work-around for ThinkPad 535.
Add a new configuration flag, KBD_NORESET (0x20) to tell scprobe() not
to reset the keyboard.
IBM ThinkPad 535 has the `Fn' key with which the user can perform
certain functions in conjunction with other keys. For example, `Fn' +
PageUP/PageDOWN adjust speaker volume, `Fn' + Home/End change
brightness of LCD screen. It can also be used to suspend the system.
It appears that these functions are implemented at the keyboard level
or the keyboard controller level and totally independent from BIOS or
OS. But, if the keyboard is reset (as is done in scprobe()), they
become unavailable. (There are other laptops which have similar
functions associated with the `Fn' key. But, they aren't affected by
keyboard reset.)
ThinkPad 535 doesn't have switches or buttons to adjust brightness and
volume, or to put the system into the suspend mode. Therefore, it is
essential to preserve these `Fn' key functions in FreeBSD. The new
flag make scprobe() skip keyboard reset.
If this flag is not set, scprobe() behaves in the same say as before.
(If we only knew a way to detect ThinkPad 535, we could skip keyboard
reset automatically, but...)

Alot of fixes from kazu:
1. All the suggestions earlier made by Bruce: renaming some symbols,
stricter error checking, removing redundant code, etc.
2. The `psm' driver preserves the default counter resolution and
report rate, whatever they are after reset. (Based on reports and
suggestion from Nate and Rob Bolin).
3. The `psm' driver now does not check the so-called sync. bit in the
first byte of the data packet by default, so that the tapping feature
of ALPUS GlidePoint works (based on reports from Louis Mamakos). I
tested the code with ALPUS Desktop GlidePoint (M/N GP101) and found
no problem; tapping worked. It appears ALPUS produces several models
of GlidePoint. I hope the other models are OK too.
The check code can still be activated by defining the PSM_CHECKSYNC
option in the config file. (The bit checking slightly reduces, if not
completely eliminates, weird mouse behavior cased by unsynchronized
mouse data packets. It also helps us to detect if the mouse interrupt
can ever be lost. But, well, if there are devices which cannot be
supported this way...)
4. The `psm' driver does not include the protocol emulation code by
default. The code can still be compiled in if the PSM_EMULATION option
is specified in the config file. Louis Mamakos suggests the emulation
code is putting too much in the kernel, and `moused' works well.
I will think about this later and decide if the entire emulation
code should be removed.
5. And, of course, the fix in `scprobe()' from Bruce to cure the
UserConfig problem. My code in `kbdio.c' is slightly different from
his patch, but has the same effect. There still is a possibility that
`scprobe()' gets confused, if, for whatever reasons, the user holds
down a key for very long time during the boot process. But we cannot
cope with everything, can we?

/* make screensaver happy */

Screen saver related fixes.
1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare
loading/unloading of a screen saver. The screen saver calls these
functions to notify syscons of loading/unloading events.
It was possible to load multiple savers each of which will try to
remember the previous saver in a local variable (`old_saver'). The
scheme breaks easily if the user load two savers and unload them in a
wrong order; if the first saver is unloaded first, `old_saver' in the
second saver points to nowhere.
Now only one screen saver is allowed in memory at a time.
Soeren will be looking into this issue again later. syscons is
becoming too heavy. It's time to cut things down, rather than adding
more...
2. Make scrn_timer() to be the primary caller of the screen saver
(*current_saver)(). scintr(), scioctl() and ansi_put() update
`scrn_time_stamp' to indicate that they want to stop the screen saver.
There are three exceptions, however.
One is remove_scrn_saver() which need to stop the current screen saver
if it is running. To guard against scrn_timer() calling the saver during
this operation, `current_saver' is set to `none_saver' early.
The others are sccngetc() and sccncheckc(); they will unblank the
screen too. When the kernel enters DDB (via the hot key or a
break point), the screen saver will be stopped by sccngetc().
However, we have a reentrancy problem here. If the system has been in
the middle of the screen saver...
(The screen saver reentrancy problem has always been with sccnputc()
and sccngetc() in the -current source. So, the new code is doing no
worse, I reckon.)
3. Use `mono_time' rather than `time'.
4. Make set_border() work for EGA and CGA in addition to VGA. Do
nothing for MDA.
Changes to the LKM screen saver modules will follow shortly. YOU NEED
TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES.

Screen saver related fixes.
1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare
loading/unloading of a screen saver. The screen saver calls these
functions to notify syscons of loading/unloading events.
It was possible to load multiple savers each of which will try to
remember the previous saver in a local variable (`old_saver'). The
scheme breaks easily if the user load two savers and unload them in a
wrong order; if the first saver is unloaded first, `old_saver' in the
second saver points to nowhere.
Now only one screen saver is allowed in memory at a time.
Soeren will be looking into this issue again later. syscons is
becoming too heavy. It's time to cut things down, rather than adding
more...
2. Make scrn_timer() to be the primary caller of the screen saver
(*current_saver)(). scintr(), scioctl() and ansi_put() update
`scrn_time_stamp' to indicate that they want to stop the screen saver.
There are three exceptions, however.
One is remove_scrn_saver() which need to stop the current screen saver
if it is running. To guard against scrn_timer() calling the saver during
this operation, `current_saver' is set to `none_saver' early.
The others are sccngetc() and sccncheckc(); they will unblank the
screen too. When the kernel enters DDB (via the hot key or a
break point), the screen saver will be stopped by sccngetc().
However, we have a reentrancy problem here. If the system has been in
the middle of the screen saver...
(The screen saver reentrancy problem has always been with sccnputc()
and sccngetc() in the -current source. So, the new code is doing no
worse, I reckon.)
3. Use `mono_time' rather than `time'.
4. Make set_border() work for EGA and CGA in addition to VGA. Do
nothing for MDA.
Changes to the LKM screen saver modules will follow shortly. YOU NEED
TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES.

/* make screensaver happy */

Screen saver related fixes.
1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare
loading/unloading of a screen saver. The screen saver calls these
functions to notify syscons of loading/unloading events.
It was possible to load multiple savers each of which will try to
remember the previous saver in a local variable (`old_saver'). The
scheme breaks easily if the user load two savers and unload them in a
wrong order; if the first saver is unloaded first, `old_saver' in the
second saver points to nowhere.
Now only one screen saver is allowed in memory at a time.
Soeren will be looking into this issue again later. syscons is
becoming too heavy. It's time to cut things down, rather than adding
more...
2. Make scrn_timer() to be the primary caller of the screen saver
(*current_saver)(). scintr(), scioctl() and ansi_put() update
`scrn_time_stamp' to indicate that they want to stop the screen saver.
There are three exceptions, however.
One is remove_scrn_saver() which need to stop the current screen saver
if it is running. To guard against scrn_timer() calling the saver during
this operation, `current_saver' is set to `none_saver' early.
The others are sccngetc() and sccncheckc(); they will unblank the
screen too. When the kernel enters DDB (via the hot key or a
break point), the screen saver will be stopped by sccngetc().
However, we have a reentrancy problem here. If the system has been in
the middle of the screen saver...
(The screen saver reentrancy problem has always been with sccnputc()
and sccngetc() in the -current source. So, the new code is doing no
worse, I reckon.)
3. Use `mono_time' rather than `time'.
4. Make set_border() work for EGA and CGA in addition to VGA. Do
nothing for MDA.
Changes to the LKM screen saver modules will follow shortly. YOU NEED
TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES.

Screen saver related fixes.
1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare
loading/unloading of a screen saver. The screen saver calls these
functions to notify syscons of loading/unloading events.
It was possible to load multiple savers each of which will try to
remember the previous saver in a local variable (`old_saver'). The
scheme breaks easily if the user load two savers and unload them in a
wrong order; if the first saver is unloaded first, `old_saver' in the
second saver points to nowhere.
Now only one screen saver is allowed in memory at a time.
Soeren will be looking into this issue again later. syscons is
becoming too heavy. It's time to cut things down, rather than adding
more...
2. Make scrn_timer() to be the primary caller of the screen saver
(*current_saver)(). scintr(), scioctl() and ansi_put() update
`scrn_time_stamp' to indicate that they want to stop the screen saver.
There are three exceptions, however.
One is remove_scrn_saver() which need to stop the current screen saver
if it is running. To guard against scrn_timer() calling the saver during
this operation, `current_saver' is set to `none_saver' early.
The others are sccngetc() and sccncheckc(); they will unblank the
screen too. When the kernel enters DDB (via the hot key or a
break point), the screen saver will be stopped by sccngetc().
However, we have a reentrancy problem here. If the system has been in
the middle of the screen saver...
(The screen saver reentrancy problem has always been with sccnputc()
and sccngetc() in the -current source. So, the new code is doing no
worse, I reckon.)
3. Use `mono_time' rather than `time'.
4. Make set_border() work for EGA and CGA in addition to VGA. Do
nothing for MDA.
Changes to the LKM screen saver modules will follow shortly. YOU NEED
TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES.

Screen saver related fixes.
1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare
loading/unloading of a screen saver. The screen saver calls these
functions to notify syscons of loading/unloading events.
It was possible to load multiple savers each of which will try to
remember the previous saver in a local variable (`old_saver'). The
scheme breaks easily if the user load two savers and unload them in a
wrong order; if the first saver is unloaded first, `old_saver' in the
second saver points to nowhere.
Now only one screen saver is allowed in memory at a time.
Soeren will be looking into this issue again later. syscons is
becoming too heavy. It's time to cut things down, rather than adding
more...
2. Make scrn_timer() to be the primary caller of the screen saver
(*current_saver)(). scintr(), scioctl() and ansi_put() update
`scrn_time_stamp' to indicate that they want to stop the screen saver.
There are three exceptions, however.
One is remove_scrn_saver() which need to stop the current screen saver
if it is running. To guard against scrn_timer() calling the saver during
this operation, `current_saver' is set to `none_saver' early.
The others are sccngetc() and sccncheckc(); they will unblank the
screen too. When the kernel enters DDB (via the hot key or a
break point), the screen saver will be stopped by sccngetc().
However, we have a reentrancy problem here. If the system has been in
the middle of the screen saver...
(The screen saver reentrancy problem has always been with sccnputc()
and sccngetc() in the -current source. So, the new code is doing no
worse, I reckon.)
3. Use `mono_time' rather than `time'.
4. Make set_border() work for EGA and CGA in addition to VGA. Do
nothing for MDA.
Changes to the LKM screen saver modules will follow shortly. YOU NEED
TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES.

raw things (what hardware do for us, exactly) as default case,
all driver features must be _optional_. Modern VGAs have internal
configuration utilities to set cursor shape/blinking which stored
into cards ROM, and syscons nuke out such features completely
by forcing software cursor. Moreover, software cursor is hard
to distinguish on standouted (or near standouted) fields and
tends to disappearse from the screen.
Set "flags 0x4" to enable software cursor now.
o Cleanup screen savers.
o Don't draw cursor if saver or blinker is active.
o Duplicated code moved to functons.
o Add more checks for blinker in progress, character lost otherwise
when blinker restore old contents.
o Reduce blinking counter to 3, too slow in old variant.
o Fix timeout code in scrn_timer(), old variant can reenter iself,
if action takes too long time.
o Disable visual bell for scroll lock mode, saved screen
becomes overwritted otherwise.

Screen saver related fixes.
1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare
loading/unloading of a screen saver. The screen saver calls these
functions to notify syscons of loading/unloading events.
It was possible to load multiple savers each of which will try to
remember the previous saver in a local variable (`old_saver'). The
scheme breaks easily if the user load two savers and unload them in a
wrong order; if the first saver is unloaded first, `old_saver' in the
second saver points to nowhere.
Now only one screen saver is allowed in memory at a time.
Soeren will be looking into this issue again later. syscons is
becoming too heavy. It's time to cut things down, rather than adding
more...
2. Make scrn_timer() to be the primary caller of the screen saver
(*current_saver)(). scintr(), scioctl() and ansi_put() update
`scrn_time_stamp' to indicate that they want to stop the screen saver.
There are three exceptions, however.
One is remove_scrn_saver() which need to stop the current screen saver
if it is running. To guard against scrn_timer() calling the saver during
this operation, `current_saver' is set to `none_saver' early.
The others are sccngetc() and sccncheckc(); they will unblank the
screen too. When the kernel enters DDB (via the hot key or a
break point), the screen saver will be stopped by sccngetc().
However, we have a reentrancy problem here. If the system has been in
the middle of the screen saver...
(The screen saver reentrancy problem has always been with sccnputc()
and sccngetc() in the -current source. So, the new code is doing no
worse, I reckon.)
3. Use `mono_time' rather than `time'.
4. Make set_border() work for EGA and CGA in addition to VGA. Do
nothing for MDA.
Changes to the LKM screen saver modules will follow shortly. YOU NEED
TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES.

Screen saver related fixes.
1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare
loading/unloading of a screen saver. The screen saver calls these
functions to notify syscons of loading/unloading events.
It was possible to load multiple savers each of which will try to
remember the previous saver in a local variable (`old_saver'). The
scheme breaks easily if the user load two savers and unload them in a
wrong order; if the first saver is unloaded first, `old_saver' in the
second saver points to nowhere.
Now only one screen saver is allowed in memory at a time.
Soeren will be looking into this issue again later. syscons is
becoming too heavy. It's time to cut things down, rather than adding
more...
2. Make scrn_timer() to be the primary caller of the screen saver
(*current_saver)(). scintr(), scioctl() and ansi_put() update
`scrn_time_stamp' to indicate that they want to stop the screen saver.
There are three exceptions, however.
One is remove_scrn_saver() which need to stop the current screen saver
if it is running. To guard against scrn_timer() calling the saver during
this operation, `current_saver' is set to `none_saver' early.
The others are sccngetc() and sccncheckc(); they will unblank the
screen too. When the kernel enters DDB (via the hot key or a
break point), the screen saver will be stopped by sccngetc().
However, we have a reentrancy problem here. If the system has been in
the middle of the screen saver...
(The screen saver reentrancy problem has always been with sccnputc()
and sccngetc() in the -current source. So, the new code is doing no
worse, I reckon.)
3. Use `mono_time' rather than `time'.
4. Make set_border() work for EGA and CGA in addition to VGA. Do
nothing for MDA.
Changes to the LKM screen saver modules will follow shortly. YOU NEED
TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES.

/* make screensaver happy */
|
Screen saver related fixes.
1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare
loading/unloading of a screen saver. The screen saver calls these
functions to notify syscons of loading/unloading events.
It was possible to load multiple savers each of which will try to
remember the previous saver in a local variable (`old_saver'). The
scheme breaks easily if the user load two savers and unload them in a
wrong order; if the first saver is unloaded first, `old_saver' in the
second saver points to nowhere.
Now only one screen saver is allowed in memory at a time.
Soeren will be looking into this issue again later. syscons is
becoming too heavy. It's time to cut things down, rather than adding
more...
2. Make scrn_timer() to be the primary caller of the screen saver
(*current_saver)(). scintr(), scioctl() and ansi_put() update
`scrn_time_stamp' to indicate that they want to stop the screen saver.
There are three exceptions, however.
One is remove_scrn_saver() which need to stop the current screen saver
if it is running. To guard against scrn_timer() calling the saver during
this operation, `current_saver' is set to `none_saver' early.
The others are sccngetc() and sccncheckc(); they will unblank the
screen too. When the kernel enters DDB (via the hot key or a
break point), the screen saver will be stopped by sccngetc().
However, we have a reentrancy problem here. If the system has been in
the middle of the screen saver...
(The screen saver reentrancy problem has always been with sccnputc()
and sccngetc() in the -current source. So, the new code is doing no
worse, I reckon.)
3. Use `mono_time' rather than `time'.
4. Make set_border() work for EGA and CGA in addition to VGA. Do
nothing for MDA.
Changes to the LKM screen saver modules will follow shortly. YOU NEED
TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES.

Interim patch/kludge for keyboard lock-up when `kbdcontrol' tries to
change typematic rate, or the X server (XFree86 or Accelerated X)
starts up.
So far, there have been two independent reports from Dell Latitude XPi
notebook/laptop owners. The Latitude seems to be the only system which
suffers from this problem. (I don't know the problem is with the
entire Latitude line or with only some Latitude models) No problem
report has been heard about other systems (I certainly cannot
reproduce the problem in my -current and 2.2 systems).
In 3.0-CURRENT, 2.2-RELEASE and 2.2-GAMMA-970310, when programming the
keyboard LED/repeat-rate, `set_keyboard()' in `syscons' tells the
keyboard controller not to generate keyboard interrupt (IRQ1) and then
enable tty interrupts, expecting the keyboard interrupt doesn't occur.
It appears that somehow Latitude's keyboard controller still generates
the keyboard interrupt thereafter, and `set_keyboard()' doesn't see
the return code from the keyboard because it is consumed by the
keyboard interrupt handler.
The patch entirely disables tty interrupts while setting LED and
typematic rate in `set_keyboard()', making the routine behave more
like the previous versions of `syscons' (versions in 2.1.X and
2.2-ALPHA, -BETA, and some -GAMMAs). The reporter said this patch
eliminated the problem.
(I also found another typo/bug, but the reporter and I found that it
wasn't the cause of the problem...)
This should go into RELENG_2_2.

Screen saver related fixes.
1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare
loading/unloading of a screen saver. The screen saver calls these
functions to notify syscons of loading/unloading events.
It was possible to load multiple savers each of which will try to
remember the previous saver in a local variable (`old_saver'). The
scheme breaks easily if the user load two savers and unload them in a
wrong order; if the first saver is unloaded first, `old_saver' in the
second saver points to nowhere.
Now only one screen saver is allowed in memory at a time.
Soeren will be looking into this issue again later. syscons is
becoming too heavy. It's time to cut things down, rather than adding
more...
2. Make scrn_timer() to be the primary caller of the screen saver
(*current_saver)(). scintr(), scioctl() and ansi_put() update
`scrn_time_stamp' to indicate that they want to stop the screen saver.
There are three exceptions, however.
One is remove_scrn_saver() which need to stop the current screen saver
if it is running. To guard against scrn_timer() calling the saver during
this operation, `current_saver' is set to `none_saver' early.
The others are sccngetc() and sccncheckc(); they will unblank the
screen too. When the kernel enters DDB (via the hot key or a
break point), the screen saver will be stopped by sccngetc().
However, we have a reentrancy problem here. If the system has been in
the middle of the screen saver...
(The screen saver reentrancy problem has always been with sccnputc()
and sccngetc() in the -current source. So, the new code is doing no
worse, I reckon.)
3. Use `mono_time' rather than `time'.
4. Make set_border() work for EGA and CGA in addition to VGA. Do
nothing for MDA.
Changes to the LKM screen saver modules will follow shortly. YOU NEED
TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES.
