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.

    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

      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.
