I have an ATI Radeon X600 using the open source radeon driver. I updated from Feisty, but in the upgrade changed from Compiz-Fusion repositories to the official Ubuntu packages. I have experienced the freezes described above, especially when doing something window management related, like putting a window to back (with middle mouse button).
After I *switched off the animations plugin*, I haven't had any freezes. This is going on a couple of days now without any problems. (And I can really do without the animations plugin anyway...) Only switching focus animations off was not enough. ** Attachment added: "xorg.conf" http://launchpadlibrarian.net/10353957/xorg.conf -- X freezes when compiz is enabled on ATI cards https://bugs.launchpad.net/bugs/108527 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
