Public bug reported: Description: Ubuntu 12.04 LTS Release: 12.04
xserver-xorg-video-intel: Installed: 2:2.17.0-1ubuntu4 compiz: Installed: 1:0.9.7.8-0ubuntu1.2 linux-image-generic: Installed: 3.2.0.27.29 OS Type: 64 bit Recently, external monitor output from my laptop has started being wavy and hard to see. Additionally the screen resolution on the laptop monitor does not seem to be correct (output does not fill entire screen). It is almost as if the resolution for the external monitor and the refresh rate for the internal LCD displays were being switched. This behaviour is definitely a regression from versions of Ubuntu prior to Precise, but may also be a recent regression on Precise itself (I am not sure when I last tried an external monitor). I also note that I randomly get "Ubuntu has encountered an error" messages that appear with or without an external monitor and occasionally Compiz dies, but I have no idea if these are connected to the problems I am having with the external monitor. This behaviour would seem similar to Bug #614238, but a fix has supposedly been released for that bug some time ago. ** Affects: linux (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/1033642 Title: external VGA projector output appears wavy on Dell e6220 with Intel Sandybridge Mobile driver (i915) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1033642/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
