Error on launch: GLib-GObject-CRITICAL on Archlinux

Installation & Configuration Linux
#1

I was using ardour just fine and in the meantime i upgraded my system with pacman. I noticed that ardour crashed and i quickly tried to run it back.
In the console now this is printed:

This might cause Ardour to run out of memory before your system runs
out of memory. You can view the memory limit with 'ulimit -l', and it
is normally controlled by /etc/security/limits.conf

I checked the packages that were affected on /var/log/pacman.log but they shouldn’t be of impact. I have another archlinux computer with the same version of the packages and ardour works there, so it might be a matter of configuration.

Im running gnome on xorg, but on this computer, ardour doesn’t start even on wayland. Does somebody have an idea on how to tackle this problem?

#2

Did you rebuild after updates ? Or is this an official nighlty version download ?

#3

I installed first the ardour package in the Archlinux official repositories, then i rebuilt with the ardour8-git aur package: none of the two worked.
The investigation followed and i tried to log into another session: Hyprland (a compositor for wayland) and it worked fine there, no errors.
Then i created another user to see if there was some system wide configuration error with gnome, but with this other user “alias” ardour works, in gnome wayland and xorg.
Now im trying to figure out what is the problem in my gnome instance with my user:

  • moved the old .config/ardour8 directory
  • purged .cache/ardour8
  • cleared .config/dconf/user
  • diffed the enviroment variables between a working instance and the problematic gnome instance
    At this point i dont really know how to move forward :confused:
