Public bug reported:

Binary package hint: xorg

Previous bug report: https://bugs.launchpad.net/ubuntu/+bug/644650

Okay, this is the second time I'm submitting this bug report (the first
one is linked above). This time I actually managed to do a proper report
with apport-bug, having used another tty (i.e. ctrl+alt+f6) that did not
have the screen corruption. The previous report was submitted manually
because I was unable to access a working terminal at the time of
corruption. In my earlier report I managed to solve the problem, but
apparently it was only for a single session. I left my PC on for a while
and after a recent reboot things are back to the way they were.

So... I am getting this strange screen corruption each time I boot
Maverick. It happens in normal as well as recovery mode. At first I can
see proper kernel boot log (I disabled the splash screen), but just
before the gnome is supposed to show up I get these white vertical lines
displayed instead (http://yfrog.com/n5stripessj). It appears that these
lines are covering up a command prompt underneath. I can login by
blindly typing in my username and password, but I cannot efficiently use
a console that does not display anything useful.

Apparently there is something wrong with the nvidia display driver
because the xorg logs report that the module fails to load for some
reason. I'm using a fully updated Ubuntu Maverick here. Applying the fix
I described in my prev. report does not work any more. I even tried
removing and reenabling the nvidia driver in "Additional Drivers"
window. Recovery mode is bugged as well, but I can boot into Gnome with
safe graphics by tapping the down arrow three times in the hidden
recovery menu and hitting enter.

Suggestions?


Additionally I'd like to voice my complaint against the use of HTTP
referers on this website (launchpad.net), as this is the second time I
had to rewrite the whole bug report, having lost the first one in a
denial as a result of my browser blocking the HTTP referers due to
security reasons.
