Same issue on Ubuntu 12.04 Beta 2 with disper 0.3.0-1 and a GeForce 320M on a MacBook Pro.
I'm using autorandr/autodisper to control disper. The first switch worked fine, after that the problem occured. ** Also affects: disper (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/908856 Title: Error: Unpack requires a string argument of length 4 To manage notifications about this bug go to: https://bugs.launchpad.net/disper/+bug/908856/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
