My external monitor stopped working after unplugging it. I can see the login prompt to start a session, but once I log in the KDE logo appears for a second and then it’s gone and the monitor won’t display anything. It has worked normally until now, and I’m not sure what causes the flaw. I didn’t update anything before or after this happened and the system is up-to-date. I tried both HDMI and USB-C (to HDMI dongle).
I found a post (“Monitor Stopped Working Suddenly – Displays at login, not after” – I don’t seem to be allowed to post the link) and changing users works, but I’d like to stay with the actual user if possible.
Any ideas on what may have caused the issue and how to fix it?
