Make the blank screen saver work with MDA and CGA. The fade and green savers are also modified so that they behave in the same way as the blank saver on MDA and CGA, although it's not the way these screen savers are supposed to work, but fading monitor and tickling green monitor cannot be done on MDA and CGA, AFAIK. So, this is the second best solution. As of this change, the current state of support of screen savers is summarized in the following table. MDA CGA EGA VGA blank OK OK NA OK daemon OK OK OK OK fade * * NA OK green * * NA OK snake OK OK OK OK star OK OK OK OK OK: works NA: doesn't work, the module cannot be loaded for this adapter. *: behave the same way as the blank saver. As you can see, EGA is left out for now. But, we can do no better, as EGA registers cannot be read... Reviewed by: sos

Incorporated lots of fixes and suggestions from Bruce and changes to facilitate the new saver loading/unloading notification interface in syscons. daemon_saver: - M_NOWAIT was wrong, since NULL returns are not handled. Just use M_WAITOK. - use `ostype' instead of hard-coded "FreeBSD". Now there is no more hard-coded string! (But, who will run this screen saver on other OS?!) - put macros and data declarations in a consistent order. - -DDEAMON_ONLY and -DSHOW_HOSTNAME options added in the previous commit are removed. Options of this kind can go stale and no one notices because no one uses them. DEAMON_ONLY is just removed. SHOW_HOSTNAME is made default. snake_saver: - use `ostype' and `osrelease' as in the daemon saver. The string changes slightly - there was a hyphen after "FreeBSD"; now there is a space. (It is consistent with uname -a, like the daemon server already is.) all screen savers: - Use the new add_scrn_saver()/remove_scrn_saver() in syscons.c to declare loading/unloading of a screen saver. Removed reference to `current_saver' and the variable `old_saver' as they are not necessary anymore. - The blank, fade and green screen savers manipulate VGA registers. Module loading should fail for non-VGA cards. - `scrn_blanked' is consistently treated as a number/counter rather than boolean. - Some savers touch `scp->start' and `scp->end' to force entire screen update when stopping themselves. This is unnecessary now because syscons.c takes care of that. - cleared up many unused or unnecessary #include statements. - Removed -DLKM from Makefiles. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THIS CHANGE.

Next syscons update (given up on numbering :) Removed screensavers from syscons, they are now LKM's. This makes it possible to do some really "interesting" screensavers... Fixed bug that sometimes caused garbage to appear when leaving "scroll-lock" history. Reformattet indentation, it got too deep for a normal 80 pos screen. Split up in syscons.c & syscons.h for use with the saver-lkm's. Temporarily removed -s option from vidcontrol, savers should now be loaded with modload.

Introducing "Jumping Daemon" screen saver. This is really cute and eye-catching :-) Submitted by: ssigala@globalnet.it Also fixed some `extern' declarations in saver.h.
