When I resume from a suspend, Ubuntu 12.04 will come back ok for about 10 seconds, and then the screen blanks out. After about another second or so, it returns to the login screen for Unity 2d. It normally runs Unity 3d. How can I fix this? I've lost a lot of work from this problem.
I sometimes get a error report window asking me to report a Compiz crash after rebooting. I think it may be Compiz or the Xorg server causing the problem. I'm not really sure.
Thanks if you can provide help.
