Public bug reported:

Binary package hint: xserver-xorg-video-nouveau

This report was posted first at ubuntuforums, but to no avail. Please
see http://ubuntuforums.org/showthread.php?t=1480590 for the same text
:-)

I have made no progress so far.


Important to note, that there is no TV-out on this laptop.
 
 After a clean install of Kubuntu 10.04 / Lucid Lynx, KDE exits intermittently to the login screen; sometimes after 15 minutes, sometimes after a longer time.
 
 A workaround seemed installing LXDE and using that instead, but the problem arises there as well, but not as often (every few hours).
 
 Other symptoms:
 TV-out is detected and activated at 1024x768
 Laptop LCD (1200x800) is degraded to run at 1024x768
 
 I have no xorg.conf or other X configuration.
 
 There is no external monitor connected.
 
 I found some people on other distro's with the problem, but no solution yet. I hoped it would be solved after an apt-upgrade; has anyone here the problem or a solution?
 
 This thread runs till a month back, with no result:
 http://www.mail-archive.com/nouveau@.../msg05364.html
 
 Here the problem is solved by installing a 6.30 kernel:
 http://bbs.archlinux.org/viewtopic.php?pid=567438
 
 Here's fix for a similar, but in my understanding inversed, situation, close to a year ago:

I expected to have one video connector active ("internal" LCD), at the
right resolution (1280x800)

Instead, I got two active connectors, one of which does not exist (TV)
and the other in compatibility resolution (1024x768)
