I noticed this too. Sometimes I'm capable to work for hours and then some app windows turn to gray color (as working) and if I minimize that window than the system freeze.
In fact, if some music is playing, it's keeping playing! But this issue shows up even without music, video or any kind of multimedia task running and no keyboard shortcut works. I'm disabling compiz and testing again. -- jaunty freezes suddenly https://bugs.launchpad.net/bugs/347848 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
