Bugzilla – Bug 438208
GUI distorted/flickers switching runlevels and logging in to KDE
Last modified: 2008-10-23 13:35:49 UTC
See summary. It is hard to describe: The distortion interrupts the display of the GUI various times, but it always returns to normal. It is more or lessa cosmetic issue. I can upload a short video showing what happens (and showing me, damned glare screen), maybe that explains it. Video hardware: Model: "Intel Mobile GM965/GL960 Integrated Graphics Controller" Vendor: pci 0x8086 "Intel Corporation" Device: pci 0x2a03 "Mobile GM965/GL960 Integrated Graphics Controller" SubVendor: pci 0x144d "Samsung Electronics Co Ltd"
I bet, that's a duplicate. Try adding the line Option "AccelMethod" "XAA" to 'Section "Device"' of your /etc/X11/xorg.conf. *** This bug has been marked as a duplicate of bug 437739 ***
Partially helps. It removes the flickering before the KDM screen appears, but it still flickers twice while the splash screen is running.
