multiple users using nwg-dock and switching between them

[moesgaard]

I have 3 users on my system and they are all setup with sway and nwg. If I login with user1 in sway and nwg and i get the nwg-Dock showing up, if I then logout. Then switch to user2 with sway and nwg, everything except nwg-dock is working.

if i try and manually run "nwg-dock -r" I get a info warning it is running but nothing happens.

Steps to reproduce the behavior: have multiple users use nwg-dock

I have the following autostart

exec rm /tmp/nwg-shell-check-update.lock
exec wlsunset -t 4500 -T 6500 -l 55.6761 -L 12.5657 -g 1.0
exec swaync -s /home/USERNAME/.config/swaync/preset-0.css
exec nm-applet --indicator
exec_always nwg-autotiling
exec_always nwg-drawer -r -c 6 -is 60 -fscol 2 -ovl -g WhiteSur-Dark -i Mkos-Big-Sur-Panel-white -s preset-0.css -term alacritty -ft
exec_always nwg-dock -r -p bottom -o DP-1 -l top -a center -i 48 -hd 10 -s preset-0.css
exec_always nwg-panel -c preset-0 -s preset-0.css
exec_always nwg-shell-check-updates
exec swayidle timeout 86400 nwg-lock timeout 86400 'swaymsg "output * dpms off"' resume 'swaymsg "output * dpms on"'
exec nwg-update-indicator

Expected behavior Dock turning up on screen

The funny thing is it is the first user that logs in that gets the dock ... so if i reboot and user e.g. User number 2, he gets it and the rest dont. even tried switching to KDE and back and same result ..

Must be some issue related to the /tmp/nwg-dock.lock file, but I can't imagine what's happening. Need to set up a multi-user machine and take a look.

[edit] Possibly just because the lock file belongs to another user. I'd need to add the user name to the file name.

One way or another, I need to recreate the issue on my side.

[moesgaard]

Yup can confirm if i log in and remove /tmp/nwg-dock.lock file and den do sway reloading it works :) could it be solved with nwg-dock-username.lock ?? or nwg-dock-sessionname.lock ??

[nwg-piotr]

I need an environment variable specific to the user. What do you mean by sessionname?

[nwg-piotr]

XDG_SESSION_ID value should be user-specific. Does it change for you when you log in as another user?

[moesgaard]

yes it changes, and i meant session ID

XDG_SESSION_CLASS=user XDG_SESSION_DESKTOP= ---> XDG_SESSION_ID=8 XDG_SESSION_PATH=/org/freedesktop/DisplayManager/Session5 XDG_SESSION_TYPE=wayland XDG_VTNR=1

[nwg-piotr]

Thanks. Let it be the session ID.

[nwg-piotr]

yes it changes

One more question: is it always the same for the same user? According to AI:

the XDG_SESSION_ID value is not always the same for the same user. It is specific to each user’s session and changes when a new session is created, such as when another user logs in.

[moesgaard]

no i changes for each login :) with +1

[nwg-piotr]

We will use md5-hashed user name.

[nwg-piotr]

Check if the 0.3.8 version behaves well for you, and let me know, please.

NOTE: I forgot to change the number in nwg-dock -v, so you'll still see '0.3.7' there.

[moesgaard]

can confirm it works like a charm.. switching between users is seemsless now :+1:

[nwg-piotr]

Thanks! I'll add the same function to nwg-dock-hyprland, if so.
