The driver is swapping out and being reinsertered. Depending on your card and monitor, you may just need to unplug and replug your monitor to force it to switch/set mode.
If it's killing your desktop session as well, that sounds like something you have installed is problematic as this shouldn't happen.
If you can still ping and ssh into the machine, it's still fine and doing what it should, but some other combination of things are causing your display to not come back online.
I think that's a good idea. I can't believe I didn't try unplugging the monitor.
I don't know what I would have that could cause it. I just have an out of the box Pop OS install with steam and some other regular apps. All I do on this computer is browse the web and play games for the most part.
Switch to a different tty, and see what the journal says
I had the same issue on popos Cosmic alpha and I couldn't login to the desktop, kept getting error messages since it probably didnt finish upgrading before I powered down manually, so I had to hit
Ctrl + Alt + F2
Logged with usename and password into terminal
Some terminal commands that fixed it for me (not necessarily in this order)
sudo dpgk --configure -a
sudo apt update
sudo apt full-upgrade
sudo apt autoremove
sudo apt autoclean
I'm running Cosmic and have been having issues with updates through popshop. Running updates manually through terminal has been more reliable, otherwise i gotta run sudo apt full-upgrade every now and then to fix whatever broke with popshop upgrades.
Good luck.
That doesn't happen on my machine, so I can't exactly test it and report back, but
Can you try updating in a tty? If the desktop crashes, tty sessions should be unaffected. Maybe it's just a bad version or something and it'll get resolved once the updates are properly installed.
Well it's happened multiple times now. I think it went wrong once and I did have to update within a TTY session to fix it.
Maybe I should just do that by default. Still, it feels like I shouldn't have to?
I have nothing productive to add, but I will say the same thing happens on my Windows 11 laptop from my work. And updates are forced by the management protocols, so every couple weeks I lose my screen until I restart. Classic Nvidia.
Do it over tmux. When the screen goes out switch tty, and load up the tmux session to see if it is finished.
Or is it dead even from that?
Not sure what tmux is. I tried to open the terminal using the function commands but I was having a hard time remembering which one. I tried several keys and none of them were working.
Next time it has another update I'll try to be more prepared
tmux is a terminal multiplexer. Basically if you made the session in tmux, the terminal would still be an active session and you could pull it from another tty.
Or you could do it over ssh.
