Hi,
Occasionally my Fedora workstation fails to resume (or wake?) from sleep after an idle period. I’m looking for help debugging this so I can either fix it myself or report it in a helpful way to the appropriate bug system.
When I’m not using the computer, the screen goes blank after a period of inactivity. (I’m unsure if this is the screensaver going blank or if the machine is actually going to sleep. Since it’s desktop hardware always plugged in to AC, I’ve never cared which is actually happening). Sometimes when I try to resume work, the screen comes back on and I’m presented with the Gnome unlock screen, but the screen is completely frozen. I can’t enter in my password or use the mouse at all. I haven’t figured out if the machine itself is hung or if it’s just not responding to keyboard/mouse input but this feels like a low-level hardware or kernel issue because it’s so unresponsive. Interestingly, I don’t seem to be able to send ANY keyboard commands to switch terminals or manually exit the session. It may be that I’m sending the wrong keys but things like CTRL-ALT-DEL, CTRL-ALT-F#, etc. seem to have no effect.
To date my only recourse has been to physically power cycle the device. Painful.
I’m running Fedora Workstation 43. This problem has been occuring at least since 42, maybe earlier. I’m not using any proprietary hardware drivers from NVIDIA. This system is built around an AMD Ryzen 5 5600G with integrated Radeon Graphics.
Now for my questions, mostly to help debugging the next time I encounter this
- Are there different keyboard sequences I should be using to either quite the Gnome session and force a new login or to switch terminals to see what’s going on in the machine?
- Is there anything useful I can pull from journalctl from the last reboot cycle to collect more details?
- Anything else I can do to help diagnose the root cause?
Thanks in advance!
