I recently upgraded to Ubuntu 11.04, and have it set up with 4 workspaces. Most of the time I can switch between the workspaces without a problem using ctrl+alt+left/right/up/down, but at least once a day, I manage to hit some other combination that causes all of the windows to move to workspace 1 and resize all of the terminal windows. This is extremely frustrating because I have to stop what I was doing and move everything back where I had it and resize the windows again.

What combination of things is causing this to happen and how can I disable it?

Edit: I just had this happen after unlocking my screen as well, so it may not be directly related to switching my workspaces...

Edit (Jan 11, 2012): Updates are current as of earlier this week. .xsession-errors.old has a good amount of information in it, but I don't know what is significant and what is just noise, and it doesn't contain any timestamps, so I have no idea when what happened.

The last block of lines from .xsession-errors.old:

(indicator-multiload:1791): libappindicator-WARNING **: Unable to send signal for NewIcon: The connection is closed
g_dbus_connection_real_closed: Remote peer vanished with error: Underlying GIOStream returned 0 bytes on an async read (g-io-error-quark, 0). Exiting.
nm-applet: Fatal IO error 104 (Connection reset by peer) on X server :0.
unity-window-decorator: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0.

Graphics card is an ATI FirePro V3700 (FireGL)

Wow, yes, it's a crash of the "unity-window-decorator". The underlying X server may be the root cause for this. This shouldn't happen. This may be best treated as a bug report to Ubuntu, for this I suggest:

  • Edit /etc/default/apport and set enabled=1
  • Reboot
  • Log in and start doing stuff
  • When the crash happens, you'll get a prompt to file a bug, follow the instructions.
  • Afterwards, disable apport (enabled=0) as it consumes extra resources.

As a way to stop this from giving you trouble, I can suggest two things:

  1. Use the "classic" environment, which doesn't use Unity or stress the graphics hardware so much.
  2. Upgrade to Ubuntu 11.10, things may be more stable, and if you keep experiencing the same problem, you can switch to Unity 2d, which is much closer to the experience you're used to.
