Bit of an odd one - resume from suspend = black screen

But if I issue a swaymsg reload it works, but kills firefox (not a problem).

I use a keybind to run swaymsg reload it works. Baffled.

Running on the AMD iGPU not the nVidia dGPU.

Are you using an external monitor?

In case you do then I can confirm that I have the same issue. For me it is a random monitor, i.e. sometimes the external monitor, sometimes the laptop screen. It does not occur very often and I so far wasn’t able to replicate this bug on purpose.

For some time I thought that it was only occurring when the laptop wasn’t connected to a charger, but I occasionally had this happening while charging…

No, just the laptop screen and reproducible 100% of the time. Have seen multiple reports on Reddit. Tried to run a systemd service on resume, but can’t get it to work.

Unless I gave it a proper “man look” :smiley:

Hi TheRaOct,
I am facing the same problem! If the external monitor is connected, the display is blank on resume from suspend, but without external monitor it works fine. I’m on Arch Linux (Ryzen 5700U, amdgpu graphics) on Sway+Wayland. The problem does not arise on Plasma+XOrg.
Did you find a solution to the problem?

I just reload the config and it “fixes it” (mod+shift+c).

Reloading sway sometimes messes up my running browser sessions, so Id’ like to avoid that. I can get the screens back after pressing Ctrl-Alt+F1/F2 etc., but I want to avoid that inconvenience.

Yes, it kills Firefox, but mine is set to restore tabs, so it becomes a minor inconvenience. Interesting though, will try the swapping tty trick next to see if it works for me.

I found that if I use wdisplay it shows the black monitors as disabled. Setting them to enabled activates them, but for some reason it will in most cases only allow the low resolutions. But it is usually enough to save my work and just restart :smiley:
Other than that I usually just execute kanshi (which I use to automatically apply my monitor layout anyway; so in the end it might not be a sway problem in my case but rather a kanshi problem) again and it will just reset my monitor layout. But this also doesn’t seem to work 100% of the time, so I can’t give you a solution that will work all the time :frowning:
