Comment 18 for bug 441873

same thing happens here, on a dell vostro a90 (which is a rebranded mini9, essentially).

running stock ubuntu 9.10, intel gma950 video card.

when connecting a vga external monitor and opening the display applet (enable the monitor), total system freeze.

if before enabling the monitor, i run "metacity --replace", then everything works just fine.

so it's definitely compiz-only problem.

if you need any more info, config files, lspci output, etc, i'd be willing to post whatever is required, just let me know what.

would be nice to get this fixed! :)
