Bazzite

+1 for a weird bazzite issue.

Im sorry I havent got advice - just a similar problem. If my TV is turned off for a period of time, when I turn it on bazzite no longer outputs anything. I have to sleep cycle the PC for it to work again

I have turned off all power management stuff related to the display (no dimming, sleep etc) and it still just dies eventually.

I changed my power switch to be sleep on press. Cycle that after the display is on, works after.

Might be a Wayland issue, according to this bug report.

Do you have a second monitor you can use, or maybe a way to remote in? I'm wondering if the television is detected at all. If so, what resolution is it set at when it is working and when it is not? What refresh rate?

Can you rule out hardware as the cause? Try booting from a live image. You can make a Ventoy flash drive and place several different live images in there. Try booting from Debian and Manjaro. See if you can reproduce with Mint 21.

If it all seems consistent, especially with that older Mint distro, then I would consider this a hardware issue. I'm that case, is your TV expecting HDMI 2.1? Can you try a different cable?

I had the same on my KVM with Bazzite. No other distro I’ve had does this too.

I need to first switch the KVM over to Bazzite PC and then the monitor will pick up video. Otherwise I have to restart for it to appear.

Super annoying but I’ve conditioned myself to switch over before powering on now.

I'm having a similar issue with my XR glasses. I have to plug them in while it's booting before the log in screen or else they wont work. They work just fine on other distros. I'm considering hoping but I really like bazzite. I'm using the KDE version.

I have a similar issue mirroring my desktop to my tv via HDMI cable; it sees the tv but doesn't let me mirror to it or arrange the displays. Its distro independent, so definitely something with Wayland or plasma. I eventually gave up and booted over to windows.
