"videodrone"- type problems with 2.6.1

[shade266]

i am running a 2.6.1 kernel that i recently built. the install works wonderfully except when i log out and/or attempt to shut down. the problem being the screen having a variation of colorrs. also while logging out the last image that was being projected is mixed in with all the colors as well. the problem is quite difficult to explain more in detail but it is akin to a picture tube going bad on an old television. the monitor i have is only 5 months old and the problem is not w/ the monitor.
