I have the same problem, x-session-manager around 75% and gdm around 25% CPU usage. As an effect, clicked links anywhere outside the browser doesn't open a new tab in firefox. Unlike Yann I still can open new programs.
The problem mostly occurs over night after having my pc on less than 2 days. Till last week I needn't restart my pc (or X) for weeks. I couldn't find anything of interest in the logfiles. -- x-session manager eats 100% CPU, nautilus won't start, applications won't start https://bugs.launchpad.net/bugs/107950 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
