Public bug reported:
Regularly the screen displays corruptions that change depending on disk
i/o, keyboard/mouse and other system activity. The screen corruptions do
not appear on each session and can be removed by selecting an
alternative resolution and then changing back (or reverting without

Removing the nomodeset kernel parameter makes GDM snappier, but it then
hangs on login (relevant portion of syslog attached).

I am trying to use the nouveau drivers on a recent (today) install of

OK, `gdb64 /usr/lib/xorg/Xorg 2>&1 | tee gdb-Xorg.txt' works. The

some love.
With all the complaints from gdb out of the way it seems that the issue
shows up as the corrupted shared library list
I have sorted out the syscall-template.S issue by getting the libc6
source.
I have found places saying that the cause of gdb not liking the binary
is because of arch incompatibility (32 v 64). I tried this with no
change.

does LTS actually mean. Without a launcher, what is the point of unity?

This or a similar bug is still sporadically affecting me. As for Hamil,
no obvious cause, no recent upgrade. The only path to fix is to reatart
