Fix #16 works fine so far here (2.6.38-8-generic, X220, i7-2620M Sandybridge). Thanks!
However, I'm additionally affected by #22 (4): I cannot dock/undock the X220 with the Lenovo Minidock Plus where I have 2 screens attached via display port. With a fresh boot there are initially some issues with the desktop background, which vanish after starting an app in full screen mode. However, switching between the display setups (undocked = notebook display, docked = 2 externals) is not possible without reboot). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/761065 Title: [Sandybridge] Spurious "*ERROR* Hangcheck timer elapsed... blt ring idle" messages in dmesg when using compiz To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/761065/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
