Public bug reported: When sddm is currently active (no users logged in on the desktop) and a monitor is disconnected, the screen of the remaining monitors suddenly go blank and the display manager is unusable until it is restarted.
The only way to rectify this issue is to switch to a text console and manually restart the service through systemctl. Note that this appears to only affect sddm when it is started via systemd. When sddm is executed manually as root (via the command 'sudo sddm'), this issue cannot be repeated. Attached is the sddm logs. ** Affects: sddm (Ubuntu) Importance: Undecided Status: New ** Attachment added: "sddm log of when the issue occurs" https://bugs.launchpad.net/bugs/1632940/+attachment/4760140/+files/sddm.log ** Description changed: When sddm is currently active (no users logged in on the desktop) and a monitor is disconnected, the screen of the remaining monitors suddenly go blank and the display manager is unusable until it is restarted.
