Title:
External monitor undetected over hdmi
Status in linux package in Ubuntu:
Expired
Bug description:
After the latest updates when I plug in an external monitor over HDMI
it doesn't pick it up. Unplugging and re-plugging the monitor seems to
connect but immediately drops into power-saving mode.
