Title: unable to connect external monitor Status in xorg package in Ubuntu: Incomplete Bug description: When connecting a BenQ T905 through HDMI with a resolution of around 1280x1020, the mouse starts wobling back and forth 4-5 times a second. Checking the log, it seems like the system cant decide on a correct resolution and changing it back and forth between different resolutions 4-5 times a second. There exists similar bugs for Ubuntu 14.04 based distros (Linux Mint 17), https://bugs.launchpad.net/ubuntu/+bug/1332895 and reading there it seems its a problem with something not supporting lower than average external monitor resolutions. My main screen is 1366x768. And if you scroll to the bottom of XorgLog.txt, it's actually changing the refresh rate of the external monitor between 60 and 76 4-5 times a second.
