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:
