Public bug reported: I've got this problem using lubuntu with three monitor.
I have a laptop with intel video card and set the monitors using arandr. After that: pcmanfm --desktop --profile lubuntu goes 100% cpu and can't open a new file manager window. killing the process makes it respawn and goes 100% cpu again. Only way to fix is to: killall pcmanfm && pcmanfm this usually interrupts the respawning and let you execute single file manager instances normally the version is: PCManFM 1.2.0 ** Affects: pcmanfm (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1360108 Title: pcmanfm goes 100% cpu on multi monitor desktop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcmanfm/+bug/1360108/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
