Comment 3 for bug 122652

Miguel, a picture certainly wouldn't hurt. Might be useful if we take this bug upstream.

Richard and Miguel, can you please attach your /etc/X11/xorg.conf and /var/log/Xorg.0.log files, and the output from lspci -vv?

Regarding the resolution mis-detection, that is likely to be an unrelated issue. I've had the same problem, and it's very thoroughly reported elsewhere, so for this bug report let's focus on the main issue of the horizontal lines. I've found the tool 'displayconfig-gtk' to be good at getting things configured correctly, although the tool itself has some crash bugs in it. You can also hand-edit your xorg.conf, but hopefully we can get away from doing that so much with Gutsy.
