I use a dual monitor setup with a VGA-connected normal monitor and an old TV connected via an DisplayPort to VGA adapter on the PC.
The KDE lock screen works basically, but after a few minutes, it stops giving my monitors an signal. That wouldn't be a problem if a few minutes after that, my TV doesn't get any signal at all if I return to work.
My normal monitor keeps working normally. If I unplug the normal monitor, the TV starts getting a signal again, but replugging leaves the monitor not getting a signal. The only solution for me at the moment is to restart the whole system, but that's not a real solution either. I couldn't find a mentioning in this forum nor the wiki, so I'd be glad if someone here could help me to solve this issue.
