I have Acer Extensa 5630Z with Intel integrated graphics chipset. I am getting the same problem as described in the first post.
Bear in mind I didn't have time to check the replies yet, so I will get back to you when I try solutions posted there. The porlbem is that compiz hangs randomly, sometimes after I go to another workspace with Desktop Wall enabled, sometimes with invoking Expo plugin's view of all workspaces, etc. There is no specific trigger for the hang. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/740126 Title: Something blocks compiz randomly several times per day -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
