Steam wont launch

Steam hangs upon attempt to launch, excerpt from logs:

assert_20250712193606_7.dmp[7711]: Finished uploading minidump (out-of-process): success = yes

Attempted fix via installing lib32-libnm and downgrading lib32-glibc as mentioned by 2023 posts to no avail

/that/ it wrote that dump is gonna be less important than /what/ it wrote there (or frankly the stdout)

Also please use [code][/code] tags, not "quote" tags. Edit your post in this regard.

Fixed the code format, sorry about that. As for log files I found that two assert.dmp files are made every crash in /tmp/dumps/ and will attach what I assume is most relevant plus the gdb output I got from following the archwiki.

assert_20250713070828_4.dmp

assert_20250713070828_7.dmp

Is this some wayland session?
Does it work on X11/openbox?
Does your wayland compositor (which) have xwayland enabled?

big · 2025-07-13 15:22:48

Wayland with SwayFX, havent tried X11 or openbox, and I am unsure of how to check for xwayland
Line 3 of ~/.config/sway/config this, if that has any use

exec dbus-update-activation-environment WAYLAND_DISPLAY XDG_CURRENT_DESKTOP=sway DISPLAY

seth · 2025-07-13 15:26:17

https://wiki.archlinux.org/title/Sway#Xwayland but idk about swayfx, can you start https://archlinux.org/packages/extra/x86_64/xterm/ ?

big · 2025-07-13 15:33:41

Appears DISPLAY doesnt work, despite calling DISPLAY as a variable in my sway config. I take it I have something more to set in systemd?

xterm: Xt error: Can't open display: 
xterm: DISPLAY is not set

seth · 2025-07-13 15:36:37

despite calling DISPLAY as a variable in my sway config

What exactly have you configured there?
the wayland compositor is supposed to start an xwayland session and set the proper DISPLAY variable, you don't have to configure anything (except for xwayland support on/off)

But at least we know why steam doesn't work.
You can probably run it on some X11 session and possibly a non-broken/misconfigured wayland compositor as well.

This bit from earlier is what I thought would set DISPLAY variable, among others

Yeah… that's pretty much nonsense and will do absolutely nothing. ChatGPT advise?
https://wiki.archlinux.org/title/Sway#Starting

https://aur.archlinux.org/cgit/aur.git/ … D?h=swayfx has xorg-xwayland as optional dependency, do you have the package?

big · 2025-07-13 16:00:25

Ah I'm an idiot, I didnt have polkit installed to allow Sway to access systemd-logind variable info. Installed and rebooted, all good now. Thankyou for the support!

Ah I'm an idiot

No, you got it running.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
