Title:
GUI failure when reinserting HDMI cable with Intel driver
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hello,
Removing the HDMI cable on my ASUS UN42 results in EDID failure which
might be only cosmetic, however inserting the cable again causes the
crash of the whole GUI segfaulting several KDE daemons.
Manually restarting SDDM restores the GUI.
