If this is too off topic (since it's more to do with Ubuntu than XBMC), then please delete this thread, otherwise I would highly appreciated some help.

Here's my situation:

I have a machine with a Radeon 9600 video card (with HDMI) setup to be a HTPC with XBMC outputting to a TV and/or a Projector. I have connected things directly, via a HDMI switcher, and via my AV receiver and in each case the outcome is the same. If I switch the input selection on one of the devices to display another input, when I switch back to HDMI it tells me there's no signal. If I don't switch the input selection the signal stays on the TV or Projector indefinitely, so it's not that the signal actually cuts out. It seems that it just doesn't reestablish a link from the computer to the display devices. Based on my testing I know for sure it's the computer. The only way so far that I've been able to restore the connection is to hit CTRL+ATL+Backspace to restart the Windows X, which also reinitialized the display, etc. However, I'm wondering if there might be a command that I can run from the command prompt that would do the same things and restore the connection. That way I would create a keyboard or remote shortcut for this command and can restore things without having to restart Windows X.

Btw, I'm running Ubuntu 8.04.

Thanks,
Harry

You could try switching to the console with Ctrl-Alt-F1 (and then back to X with Ctrl-Alt-F7)
