I have a LG50a laptop with "ATI Mobility Radeon 9600" with a 15" SXGA+ TFT LCD and I've installed Debian testing on my box. I've installed xorg 6.9.0.dfsg.1-4 as my X server. When I use the fglrx driver that enables OpenGL direct rendering, xorg fails to run under 1152x864 resolution. When I use ati driver it works well under this resolution but there is no support for direct rendering! here is my xorg.conf

Can anyone help me out?
Just two very general suggestions:
1) Try to reduce the DefaultDepth in your xorg.conf from 24 to 16.
Sometimes this kind of problem is due to insufficient video ram making
it impossible to run the highest resolution with 24 bit depth.
2) Check the errors and warnings in your Xorg log file:
egrep '^\((EE|WW)\)' /var/log/Xorg.0.log
Maybe that will tell you were things go wrong.
