Finally got my wife away from Windows and on Fedora 40 (Gnome 46).
Now, when her PC goes to suspend and when she wakes it up, one of her 2 monitors doesn’t wake up.
Both are connected to HDMI ports (no dedicated video card, just the integrated card in her Ryzen 9).
Any ideas on what could be happening? I wouldn’t want her to go back to Winblows over something so insignificant, but she would.
This happens to me consistently on Linux Mint. My secondary monitor which is an HDMI TV resumes fine and takes over as primary. The primary screen on a Display Port over USB fails to wake up.
I’m using the edge kernel line, version 6.5. I’ll try to downgrade to 5.15 to check if this is a kernel regression.
I’m running an AMD system with embedded graphics from Minisforum, btw. What are you running and which kernel?
i got pop (fresher kernel?) and xorg but same issue you described. i keep unplugged unless i am using it but also since it will limit main monitor fps.
I have tried disconnecting and then connecting the display to see if it will wake up, but it doesn’t work. Sometimes shutting down the display and turning it on again work.
Same. Minisforum mini PC HX90 on Ryzen integrated graphics. She’s on Kernel 6.8.7-300
I managed to get it on kernel 5.15 and replicate the issue. I had to find its USB-C charger to keep it on while I power down my monitor otherwise it would hard shutdown it. So, connecting the monitor back, the weirdest thing just happened. The display rearranged, but didn’t use the new monitor. Instead, the lock screen got resized and I could see my session behind it without logging in (!).
I’ve got this on dmesg:
[119330.829398] amdgpu 0000:63:00.0: [drm] *ERROR* no VCPI for [MST PORT:00000000e7b3da3d] found in mst state 000000005563f49a
journalctl gives more details:
I got it to switch monitors using Cinammon’s Display app, but it will not take two displays at the same time.
I would totally try a kernel update, even if it meant uxing zen kernel. Older kernels is one of the reasons why I stay away from Mint and Zorin.
Weirdest thing is I could swear it didn’t use to happen on Mint 21 until I both upgraded to 21.2 and switched to the edge low latency kernel. It doesn’t bother me much, and everything else just works, plus I’m addicted to
aptitude
so I need a Debian based distro.Aptitude is the one thing Debian based distros have that beat the rest.
