debian+phosh running on PinePhone

[a-wai]

The default scale can be set in '/usr/share/phosh/rootston.ini' in the '[outputSI-1]' section.

Actually, you should create/edit '/etc/phosh/rootston.ini' if you want your config to persist across updates.

I think I've seen the same problem with s2idle, which is used by default, if the suspend lasts more than 3 minutes. 
The systemd-watchdog is killing the user session because it thinks it has not responded for more than 3min.

Hope this helps! Also, I have not seen this happening with deep sleep.

Thanks for the feedback, that should really help indeed!

Any low hanging fruits a noob with too much time on their hands might be able to tackle?

@devrtz might be, it depends on your skills and/or things you wish to learn (Debian packaging, Rust programming, C/GTK tinkering...)
Feel free to send me a PM to discuss this
