[Bug 353397] Re: When watching video, any window over video causes corrupt display and logout

[christobzr]

I have just tried twice to get a backtrace, but I have run into perhaps
another issue.

First attempt, I logged into X with a failsafe terminal session. I
issued "xterm &" to get a new terminal. Then "metacity & ; firefox &" to
get the backtrace instructions on screen. "pgrep Xorg ; sudo gdb
/usr/bin/Xorg 2>&1 | tee gdb-Xorg.txt" then in gdb "attach <num>". At
this point the screen froze, I could not change virtual terminal, I
could toggle numlock, but that was all. I hit the power button and
waited for the machine to power down.

Second attempt, I worked from one Virtual Terminal, had lynx in another
VT, ran gpm to copy paste the commands. I opened an X session with
failsafe terminal, and in my first VT issued "pgrep Xorg ; sudo gdb
/usr/bin/Xorg 2>&1 | tee gdb-Xorg.txt" then in gdb "attach <num>", this
time this command generated output, I then issued "cont" ant pressed
ctrl+alt+F7, but the screen went black, I could then not change VT, not
even turn numlock on or off. I hit power switch and waited for machine
to turn off.

I'm going to have another attempt now.
