I have now done some tests with 2.6.33 kernel with different boot parameters (always in comparison with kernel 2.6.32). I have always used the official kernel of the sidux project, no self compiled kernel. The latest BIOS is installed on my PC. Here's an overview: Kernel version: 2.6.33-0.slh.5-sidux-amd64 Kernel command line: root=/dev/mapper/sysvg-LVroot ro quiet Xorg: In Xorg.0.log no errors starting with "(EE) intel" Effects when launched X: short-term dropouts (black screen) and visual disturbances Kernel version: 2.6.33-0.slh.5-sidux-amd64 Kernel command line: root=/dev/mapper/sysvg-LVroot ro quiet video=1280x1024 i915.modeset=0 Xorg: no short-term dropouts (black screen) and no visual disturbances, but errors in the Xorg.0.log (EE) open /dev/fb0: No such file or directory (EE) intel(0): [drm] Failed to open DRM device for : No such file or directory (EE) intel(0): Failed to become DRM master. (EE) intel(0): Failed to initialize kernel memory manager Effects when launched X: Very sluggish and slow KDE Kernel version: 2.6.33-0.slh.10-sidux-amd64 Kernel command line: root=/dev/mapper/sysvg-LVroot ro quiet video=1280x1024 Xorg: In Xorg.0.log no errors starting with "(EE) intel" Effects when launched X: short-term dropouts (black screen) and visual disturbances Kernel version: 2.6.33-0.slh.10-sidux-amd64 Kernel command line: root=/dev/mapper/sysvg-LVroot ro quiet video=1280x1024 i915.modeset=0 Xorg: no short-term dropouts (black screen) and no visual disturbances, but errors in the Xorg.0.log (EE) open /dev/fb0: No such file or directory (EE) intel(0): [drm] Failed to open DRM device for : No such file or directory (EE) intel(0): Failed to become DRM master. (EE) intel(0): Failed to initialize kernel memory manager Effects when launched X: Very sluggish and slow KDE So whenever I fall on the boot parameter "i915.modeset = 0" set the short glitches and visual disturbances are gone, but the performance in X is then very bad. However, I Put the boot parameter "i915.modeset = 0" are not, the performance in the X good. But short glitches and visual disturbances are present. I've attached the logs of X (Xorg.0.log), the output of dmesg (dmesg.txt) and lsmod (lsmod.txt) for both variants in the mail. Perhaps they see a possible solution to my problems.
