Title:
Displays not properly recognized after upgrading kernel to
4.10.0-37-generic
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have a multi-monitor setup and after upgrading kernel to
4.10.0-37-generic, the displays weren't properly recognized. Only 1
monitor appears on display config and it's limited to 1024x768
resolution. Reverting kernel to 4.10.0-35-generic solves the problem.
