Something very strange happened this morning which I’d like to get a better understanding of if possible. It occurred on my mother’s computer so what happened before I jumped in to investigate and fixed the problem is based on what she told me.
When she returned and moved the mouse, the screen wouldn’t come out of power saving. As I instructed her in case of any system freeze, she did a hard reset. But from this point on the screen would never turn back on even after a full restart: GRUB and the boot console would show up, but once the login screen was supposed to be displayed the monitor remained black. The screen didn’t go in power saving as if signal was lost, just printed the black color and nothing else. The machine wasn’t frozen either as I could toggle the NumLock keyboard LED and press the power button to shutdown gracefully.
I booted the Manjaro USB install drive and did a manjaro-chroot -a
into the system. I was ultimately able to get rid of the issue by uninstalling the amdgpu-experimental
package: I had that on because her graphics card is an old GCN 1.0 model, without it you only get the even more ancient radeon module instead of amdgpu. This indicates the issue would reside with its changes.
The weird thing though is that this worked fine for an year. No updates to anything like drivers or xorg or the kernel were preformed following this morning when it booted just fine: The OS doesn’t randomly modify its core display settings without either an update or a root command to do so, making it highly bizarre that permanent breakage persisting reboot would be introduced out of nowhere.
I’d like to understand what could have happened, since even on her machine I’d rather use amdgpu to have a proper driver so I’d like to put the experimental package back. All I have so far is the Xorg.0.log I extracted from the live session after the last failed boot… not seeing any errors explaining why X would crash before the login screen, I’m not that experienced so maybe I’m missing something.
