[SOLVED] sddm rootless - how?

I've been running Arch with KDE Wayland for quite a while.

echo $XDG_SESSION_TYPE

wayland
env | grep -i wayland

DESKTOP_SESSION=plasmawayland
XDG_SESSION_TYPE=wayland
WAYLAND_DISPLAY=wayland-0
QT_WAYLAND_FORCE_DPI=96
MOZ_ENABLE_WAYLAND=1

I created /etc/sddm.conf.d/10-wayland.conf as suggested by the wiki:

[General]
DisplayServer=wayland
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell

[Wayland]
CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1

But sddm is still running as root:

ps aux | grep sddm

root       20610  0.0  0.1 153844 24580 ?        S<sl 17:47   0:00 /usr/bin/sddm
root       20687  0.0  0.1  77548 23156 ?        S<   17:47   0:00 /usr/lib/sddm/sddm-helper --socket /tmp/sddm-auth-c206e0a9-a6cb-4d50-91e1-2cc29d570670 --id 1 --start /usr/lib/plasma-dbus-run-session-if-needed /usr/bin/startplasma-wayland --user charly

What am I missing? Any suggestions?

Re: [SOLVED] sddm rootless - how?

Does sddm end up running
1. kwin_wayland
2. as root?

https://man.archlinux.org/man/sddm.conf … layServer= suggests it's gonna run "Wayland compositor as unprivileged user.", not the daemon itself?

Re: [SOLVED] sddm rootless - how?

kwin_wayland is running as user:

ps aux | grep kwin
charly         7338  0.0  0.1 162072 23996 ?        S<sl 11:20   0:00 /usr/bin/kwin_wayland_wrapper --xwayland

Re: [SOLVED] sddm rootless - how?

I'd expected sddm to run it as "sddm", not charly…

Re: [SOLVED] sddm rootless - how?

The man page describes DisplayServer option as "the display server to use for the greeter" – and the greeter (with its compositor) does indeed run as 'sddm' user:

sddm        4173  0.2  0.8 1608188 132836 tty1   S<l+ 11:24   0:00 /usr/bin/kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1
sddm        4528  0.2  0.8 2194464 134960 tty1   S<l+ 11:24   0:00 /usr/bin/sddm-greeter --socket /tmp/sddm--wCzKDb --theme /usr/share/sddm/themes/maldives

Also the account's description is "SDDM Greeter Account", further suggesting it's just for the greeter and not necessarily for the daemon:
https://github.com/sddm/sddm/blob/v0.20 … er.conf.in

I think all of what you're seeing is expected behavior.

Re: [SOLVED] sddm rootless - how?

Yikes - it seems that you are right! And the wiki is obviously incorrect or, at least, imprecise by not differentiating between sddm and sddm-greeter.

Thanks a lot!
