Apparently this is still happening to many people (including myself) and I'm getting pings and emails about the work-around that I've discovered. This is the script that I use. Don't trust me... research this yourself.
1) I login at lightdm and verify that launching anything from Unity causes a hang/crash/freeze. 2) I control-alt 1 to a console terminal and login 3) I run this script (replace "<me>" with your login name. I've called it "fixcompiz.sh" #!/bin/sh sudo service lightdm stop rm -rf /home/me/.compiz* rm -rf /home/me/.cache/.compiz* sudo service lightdm start 4) when lightdm starts it forces me over to console 7 where I can just login and continue on my happy way with a working system. I have to perform the above 4 steps on my two nvidia machines on every boot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/750386 Title: compiz crashed with SIGABRT in raise() from abort() from __libc_message() from malloc_printerr() from _int_free() To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/750386/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
