Issue:

Computer behaves normally until I turn my TV off. The computer is hooked to an Audio/Video Receiver via HDMI. I use a Geforce 4070ti, RPM Fusion drivers following the wiki guide.

When I turn the TV off nothing happens for a few seconds until the receiver detects that the TV is off. Then I hear the KDE login/logout jingle repeatedly with their SFX overlapping/garbled. I hear this because I'm using Digital Optical output for audio from the PC, and the receiver is left on.

Next when I go to turn the TV back on, I get no signal, but the computer isn't crashed or anything, just no video signal.

• This is on a fresh install of Fedora 41 KDE Spin, fully updated.

• I've tried disabling sleep, disabling the lock screen, disabling screen dimming, blanking, all their timers, set power profile to performance. None of this made any difference.
