Driver/Config issue or Hardware issue?
Before I go down the path of buying a new video card: I had recently installed Bazzite on a clean partition a few days ago having not touched Linux in a few years, and then not since the early 90s. While I ended up resorting to basic graphics mode, and then let it pick up drivers, that went well and I tested a couple games to suss out performance issues and resolve them.
Yesterday I turned on my machine to discover plasmashell had crashed and my secondary monitor (on an HDMI port with an active HDMI->DP adapter to a DP KVM) was known to the OS, but was nevertheless a black screen. Juggling connections I confirmed that Bazzite was able to render the second display (I selected different plain colors for the wallpaper to tell the difference), but only would output to the display on the straight DP connection. During juggling these connections I managed to repro the plasmashell crash.
This behavior remained even after re-installation on a clean partition (via the use all space option).
The graphics card is a GeForce 1660 Super, 1 HDMI + 1 DP outputs. heavy DP cables to a not-cheap KVM, DP to the monitors. No issues exist for the other computers in the other KVM channels, and this issue didn't occur under Win10, pre-Bazzite.
Based on that (the issue persisting), I'm suspecting either the adapter died overnight, or the graphics card is dying. But it could also be something with software updates that might have occured in the past 2-3 days. I've a new adapter arriving this afternoon, but I'm curious if anybody else has run into this?
