Black screen on reboot under Proxmox/qemu

Hi, I’m using the bazzite-deck-gnome F39 image, trying to get a VM set up in my Proxmox host to stream Steam games using Steam Remote. I’ve tried Bazzite a couple times, but after stepping through the install and booting up successfully the first time, subsequent reboots show Plymouth for a second, then drop me on a black screen with a blinking cursor at the top-left corner. I tried disabling the “quiet” kernel flag, that didn’t turn up any helpful indicators of what’s wrong. I’m not sure what the machine is doing, the qemu-guest service seems to be running, according to Proxmox, so it’s some level of running, but I can’t interact with the VM.

I just had the same problem but on real hardware. I read somewhere that F39 is old, this the one I had. I currently download the F40 kde image and shall check, shall tell here if ok.

just found another post : Black screen after login on Bazzite 40 + Wayland redux, check it
