Created attachment 25145 [details] Photo of the visual distorsions Platform: Dell Latitude D630 GPU: 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c) OS: Debian Lenny/Unstable AMD64 X-Server: 1.6 Intel-Driver: 2.7.0 Kernel: 2.6.30-rc3-00351-g2447a6d When enabling KMS, I observe huge visual errors under X (see attached photo, taken during Gnome startup). The console works fine, as does switching between X and consoles. The system runs stable. The mouse pointer is not affected by the distorsions. Without KMS but using the same setup otherwise (by setting i915.modeset=0) X works fine. In both cases I'm starting X directly into Gnome (using metacity, no fancy 3D stuff). After playing with the intel driver options, I found that disabling "Tiling" seems to fix the visual errors (although at a huge performance penalty). I've attached the X log & kern.log as well as my xorg.conf. If there is anything else I can provide, please let me know. cheers Dariush
