I couldn't reproduce the problem with unity 3.8.10-0ubuntu2 but now I can with 3.8.12-0ubuntu1. When I enable my external display with the following commands, I see a number of artifacts, presumably from chromium , even though chromium is not in use:
xrandr --output DVI-0 --primary xrandr --output HDMI-0 --right-of DVI-0 --auto xrandr --output HDMI-0 --set underscan off If I drag a window to the external screen, the window is not visible and seems to be just a rectangle filled with artifacts. If I downgrade unity to the previous release everything is fine and I can use the external screen: sudo apt-get install unity=3.8.10-0ubuntu2 unity-common=3.8.10-0ubuntu2 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/753971 Title: Display garbled upon restoring original resolution or connecting external displays -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
