ATI-8.32.5 blank screen fix
I’ve just upgraded my ATI drivers from 8.29.6 to 8.32.5, restarted my X and was greeted with a very beautiful blank/black screen. Playing a bit with my ModeLine in xorg.conf though I was able to make it work again.
I just needed to change:
Modeline "1280x1024_75.00" 138.54 1280 1368 1504 1728 1024 1025 1028 1069 -HSync +Vsync
to:
Modeline "1280x1024_75.00" 138.54 1280 1368 1504 1728 1024 1025 1028 1069
This Modeline created by gft makes my monitor work at 75Hz instead of the 60Hz that ddc provides to xorg.
I don’t know why but it looks like the new drivers don’t like the polarity options that the previous drivers had no problem with…
Anyway, here’s the part of my xorg.conf referring to my Monitor and Graphics Driver that currently works:
Section "Monitor"

And the glxgears result:
17418 frames in 5.0 seconds = 3483.523 FPS
17341 frames in 5.0 seconds = 3468.088 FPS
17428 frames in 5.0 seconds = 3485.311 FPS
17548 frames in 5.0 seconds = 3509.505 FPS
