Hey guys,
Is it cheating to change the screen depth? I change it to 24 bpp and now
cheese and totem work. Changes to /etc/X11/xorg.conf:
(in the Screen Section)
DefaultDepth 24
(in the Display SubSection)
Depth 24
Cheese doesn't show live video from the camera but I am able to take
pictures. And totem reproduces video (no sound, but hey! that it is
another thread/ticket).
Anything wrong with using X with 24bpp?
I can feel F11 on the XO-1 near.... :)
