Description Oren Held 2009-05-01 18:57:26 UTC

Version:            (using KDE 4.2.2)
OS:                Linux
Installed from:    Debian testing/unstable Packages

After wakeup from sleep mode, the unlock screen shows up.
Its background is not solid black as I'd expect, but is quite random: sometimes it shows corrupt stuff, sometimes it shows parts of the display I had before the computer was changed to sleep mode.

I'm using Xorg server v1.6.1, "intel" driver.

Sounds like a driver issue. 

In fact, a known issue and mentioned all over kubuntu's stuff:
http://www.kubuntu.org/news/9.04-release
Which has some workarounds for X. 
And probably means that the bug has been reported to Intel.
