So, I installed ccsm and ran it, hoping to use "vsync" to solve video tearing. I didn't make any changes though, but now when I try to start gnome shell or unity, I just get a completely blank desktop.
I did something similar with an older ubuntu version some time ago (hence the slow learner badge) and was able to fix it with "unity--reset", but now I'm in 12.10 and it is deprecated here.
What I've tried so far are:
Setting ccsm to defaults, and then uninstalling it.
"unity-reset" from ppa per this link: http://www.webupd8.org/2012/10/how-t...in-ubuntu.html
Also from the same link:
dconf reset -f /org/compiz/
But none of these have worked. I still can't get a unity or gnome-shell desktop. I can only use gnome-classic. My google searches aren't turning up much beyond what I've already tried.
