[Bug 1403228] [NEW] unable to connect external monitor

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

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), and reading there it seems its a problem with something not
supporting lower than average external monitor resolutions. My main
screen is 1366x768.
