Correct. The solution for us would be to use the kernel backlight control, AFAIK Ani Joshi is taking care of this for 4.2.0 . > 2) When I reduce the display resolution the display is reduced to the > top-left, and surrounded by garbage.

The X server driver can basically do it if you don't use Option "UseFBDev", but not correctly either because we don't have an equivalent for a video BIOS providing the necessary information. About the DGA thing: DGA has to be one of the most useless and incorrectly used extensions. If xmame doesn't work without it, I'd consider it broken. -- Earthling Michel Dänzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast
