I haven't compiled it yet, but here's my thoughts.
If we're going to do start doing graphical screensavers, then I
suggest making the mechanism more general, rather than requiring a
separate timeout. To this end, I recommend adding a variable whereby
the screensaver is responsible for letting syscons know if the current
mode is known to it. The new variable is scrn_saver_mode. The screen
saver is responsible for setting it when it changes the mode, and
setting it to 0 when it unblanks the screen. (The latter task should
probably be relegated to syscons.)
I haven't tested this yet; I'm recompiling now. If all goes well,
then I should have a screensaver ready hopefully tonight.
Happy hacking,
joelh
