Same problem here. Using a fresh and updated Karmic install on an HP laptop with Mobile Intel GMA 4500MHD video card.
However, it doesn't happen always. In my last test, I had two terminals open and was able to switch. Then I opened Firefox, and couldn't switch anymore. When the problem does happen, nothing crashes. It's compiz that goes to 100% CPU and thus makes xorg completely unresponsive. But it's still possible to switch to a virtual console and kill compiz. Then I can go back to X and restart Compiz. Since there are no crashes, I don't have any apport output. -- [regression] Xorg/Compiz crashes when doing Alt+Tab in Karmic https://bugs.launchpad.net/bugs/420312 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
