[Lucid] Xserver fallback to GDM: ddxSigGiveUp

[Sam_]

Binary package hint: xorg

Reference: Bug #459229

Issue occured out of a sudden while writing text in gedit and pressing enter key. (pity, some text wasn't saved, hence gone)
Screen goes black, few messages run through in milliseconds.
GDM displays, login ok.
Backtraces are in Xorg.1.log.old.
Thanks.

btw. when uploading bug report user gets info below the inbox how to report a bug (screenshot).
But according to CLI the -p option is deprecated.
$ ubuntu-bug -p xorg
Warning: The options -p/-P are deprecated, please do not use them. See /usr/bin/ubuntu-bug --help

X crash happened again.
While writing text in firefox and press enter key.
Fallback to tty and proceeding to GDM after few seconds.

[Sam_ (and-sam)]

Maybe also of interest.
Before a crash occurs, some windows which are open on different workspaces, e.g. gedit and firefox
the focused one and there only a part of the window gets some kind of overlay pattern (similar to matrix screenshot), so one can see only part of the window.
e.g. in gedit half of the window is overlayed by the pattern, firefox menu is overlayed, but webpage is visible. Sometimes the pattern is black-grey, sometimes black-green.

When moving to another workspace via ctrl+alt+arrow the pattern disappears.
When I try to make a screenshot of the overlayed window via alt+print the pattern disappears.

Stopped investigation. I'll get new hw incl. graphic card and reinstall from scratch.
