John Baptist, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p xorg-server REPLACE-WITH-BUG-NUMBER

Thank you for your understanding.

Title:
  video players (totem, vlc) crash during video mode change when using
  Xv and compiz

Status in “xorg-server” package in Ubuntu:
  Incomplete

Bug description:
  If video is playing during a video mode change, the player application
  will crash, under certain conditions.

  To reproduce: Using Lucid, nvidia drivers 195, and compiz. Play any
  video in any video player, such as totem or compiz. While the video is
  playing, change video mode, either via gnome-display-properties, or
  xrandr (in some cases it may be necessary to change video mode twice).
  The video player will crash.

  What I expect to happen: The video player doesn't crash.

  Notes: This only happens if compiz is in use; the bug is not present
  with metacity. It only happens if Xv is used for video; if you turn
  off Xv via gstreamer-properties, totem will not crash during mode
  switch (although vlc still will; presumably, it ignores that
  particular setting). This didn't happen under Jaunty with a similar
  configuration, and so is a regression. So this looks like some ugly
  interaction between Xv, compiz, and nvidia.

  Additional note: The player will also crash if it is active during a
  suspend-to-RAM/resume operation, presumably because resume involves a
  video mode change. In that case, however, there is an additional
  problem, which is that after the resume (only if a video player was
  running at the time of suspend!), Xorg consumes huge amounts of RAM
  and CPU time, and system responsiveness is seriously degraded,
  requiring a complete system restart (restarting Xorg does not
  suffice). I don't know if this is a different symptom of the same bug
  or a separate bug.

  The error message produced by totem when it crashes is:

  The program 'totem' received an X Window System error.
  This probably reflects a bug in the program.
  The error was 'BadAlloc (insufficient resources for operation)'.
    (Details: serial 507 error_code 11 request_code 133 minor_code 19)
    (Note to programmers: normally, X errors are reported asynchronously;
     that is, you will receive the error a while after causing it.
     To debug your program, run it with the --sync command line
     option to change this behavior. You can then get a meaningful
     backtrace from your debugger if you break on the gdk_x_error() function.)

  I will be happy to provide more detailed information of any sort.
