Seeing the same problem in Ubuntu 14.04.1 LTS. Interestingly, the problem doesn't appear if I start gnome-do under strace:
strace -f gnome-do Attaching strace to an already-hung gnome-do session doesn't fix it. Running gnome-do under strace, then killing strace leaves the gnome-do session running fine: strace -D -f gnome-do sleep 10 killall strace Perhaps there is a race somewhere in gnome-do's startup? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1388734 Title: Xorg freezes after starting gnome-do Status in xorg package in Ubuntu: Confirmed Bug description: Happens every time I start gnome-do. gnome-do window will alocate some screen space but not show and only mirror some parts of the background. Mouse can be moved, even some mouse-over events work. But clicking and typing is not registered (not even ctrl-alt-f1). Only way to fix the problem is to ssh in from outside and kill gnome-do. Then everything works fine again.
