From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Black screen on wake from suspend on game mode (lemmy.world)

Hi all, I have tried everything, and now I am coming here for help. Hopefully someone can tell me what's happening here. So, I have this older pc that I have converted into a steam console, first with Bazzite and now with Chimera OS. Both work very nicely, but the one issue that persisted on both distros is that when I put the pc to sleep from game mode (press xbox button>power>sleep) then wake it up, the screen is not receiving a signal, it not even a black screen, just no signal. I would have to force reboot it to be able to get in. Nothing works. I can't even get into a tty screen or do anything. It is connected to a samsung tv 65mu8000 via HDMI cable. I have UHD color input enabled for that input, just to give more details.

I have tried disabling the wake up animation like some folks suggested and that didn't do anything. I have tried disabling the display core like some other searches suggested by putting amdgpu.dc=0 in modprob.d in its own file. I have tried blocking the intel iGPU, even though this CPU doesn't have one. Nothing works. It has an intel core i7 5930k and an AMD RX 6600. I would appreciate any help or suggestions Thank you

Nothing shows on the screen. I can't even get into tty through Ctrl+alt+Fx at all

That sucks. I get no monitor signal but tty snaps it on. Can you ssh in? It would help you diagnose what is failing

I haven't tried SSH. I'll need to set it up on Bazzite first and then try it. Would it even allow SSH if it's hanging on a lock screen somewhere?

It would allow SSH if the desktop is locked, they're separate. If you can get in via SSH then you can poke around logs like dmesg and see what's up. There will probably be some messages to give you something more specific to search with.

I'll mess with that actually. There is a mobile app for ssh that I have, so might as well
