Anyone running sway as wm?

As far as I know, sway is a wayland compositor, and every app in solus are compiled to use x11, that could explain why you have problems using it. maybe xwayland could help a bit? I don't have experience with wayland nor xwayland though.

right, you cannot use lightdm.
sddm works, or just disable the login manager and login from tty.
To disable e.g. lightdm:

sudo systemctl set-default multi-user.target
sudo systemctl disable lightdm
sudo systemctl enable getty@tty1
sudo systemctl disable getty@tty2

you can then login on tty and start sway from there: sway
you can also copy the following to your ~/.bash_profile to start sway automatically when logging in from tty1 (and to set some environment variables to make applications start in wayland mode:

# If running from tty1 start sway
if [ "$(tty)" = "/dev/tty1" ]; then
export QT_QPA_PLATFORM=wayland
export QT_WAYLAND_DISABLE_WINDOWDECORATION="1"
export MOZ_ENABLE_WAYLAND=1
exec sway
fi

note that, as stated by nolan , wayland isn't supported on solus. Wayland support for nautilus has just been dropped as far as i can tell. At least it doesn't start in wayland mode anymore for me.

to enable lightdm again:

sudo systemctl set-default graphical.target
sudo systemctl enable lightdm
sudo systemctl disable getty@tty1
sudo systemctl enable getty@tty2

but i think when a) not using a touchscreen and b) not using scaling, all the x only apps still work reasonably fine in xwayland and most of the time, you won't notice it.

ps: i used it on a surface

528491 sudo systemctl set-default multi-user.target

I use that line only, to run jwm on my Solus. I never touch the lightdm or the gettys.

elfprince good to know that only this line will do too, thanks!
