I have the same problem, mplayer streaming stagevu or movie player while running, trying the option fullscreen, the desktop blacksout and system has to be shutdown, restrated.
Have swithed of the visual effect to none, lets me find how my system behaves. It seems to be ok for now -- machine freezes requiring reboot on fullscreen https://bugs.launchpad.net/bugs/360568 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
