How to troubleshoot gnome3 failures?

After running Gnome3 without any problems for the last 2 months or so, I installed compiz the other night, which appears to have corrupted my installation.

I’ve now uninstalled compiz, and tried gnome-shell --replace, but this appears to fail, and instead drops me back into the old gnome style (fallback?).

Any ideas how I can troubleshoot what’s going on?

can anyone help me out?

Check down in ~/.config/compiz and remove the file called
enable-compiz, the touch the disable file, eg;

rm ~/.config/compiz/enable-compiz
touch ~/.config/compiz/disable-compiz

There was probably no need to remove, just disable…

^ this, combined with resetting my x11 config back to install version

rm /etc/X11/xorg.conf

…has resolved the problem.

Many thanks!
