[Original Report] Recently updated to a KMS kernel & X driver in Karmic on my Thinkpad W500 with Intel graphics. Three bugs appeared: 1. After DPMS activates (e.g. xset s activate), I often (but not always) cannot get the screen to re-display anything, e.g. by typing on the keyboard or moving the mouse. The screen stays blank even though everything appears to be working fine otherwise. 2. After resume from suspend, the machine often (but again, not always) brings up the pre-suspend screen image, and hangs, not responding to any input (mouse or keyboard), and seemingly not even running applications that I would expect to update the display on their own (e.g. the clock is stuck). 3. When viewing images (e.g. in firefox or in Gnome's eog viewer), stray individual red, green, and blue pixels appear throughout the image. What's more exciting is that these stray pixels "jump around" a little bit when you drag the X window containing the image, although they seem to stay in the same general vicinity, creating a "sparkling" effect. I've noticed that the third issue (spurious red, green, and blue pixels showing up in images) only appears after a successful suspend-resume cycle. I have upgraded to kernel 2.6.31-1.14, which still has issues #2 and #3. I don't know whether screen blanking is still an issue, because I've disabled it for now. After upgrading to kernel 2.6.31-2.17 and xorg-video-intel 2:2.7.99.901+git20090702.74227141-0ubuntu1, I no longer have the suspend/resume problem, but spurious pixels persist.

After upgrading to Ubuntu kernel 2.6.31-3.19 (based on 2.6.31-rc3) I no longer have the color flickering problem, so something seems to have fixed it.
Ok, I'll mark fixed then. Thanks for the update.
