After some uptime (upwards of an hour so far), I get different kinds of display corruption on a laptop with a Radeon x1400.
Currently, I'm looking at a somewhat grainy picture which looks like a badly dithered low-colour version of the screen content. There are noticeable vertical stripes, and the whole image is shimmering. The system is working fine otherwise.
In an earlier instance, I had a pulsating green gradient covering the bottom of the screen. In addition, screen response was slow, like the proper content was only updating evers second or so.
The effect does not show in screenshots.
This is on a Debian-built 2.6.34 686 kernel, running X.org 1.7.7 and the "radeon" driver 6.13.0, libdrm2 2.4.21 from Debian packages.
I'm attaching lspci output for the card, as well as dmesg and the Xorg.log from the currently "broken" running system.
