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. 753538 1 zahl 2009-05-07 13:57:19 +0000 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.
