Hi Kristjan,
And thanks for the report.
Kristjan <[email protected]> (2025-12-28):
After a fresh Debian Testing installation (installer build 20250803+deb13u1)
with GNOME desktop (task-gnome-desktop), the created user was not added to
the 'render' group, although the group exists in the system.
What led up to the situation?
* Standard Debian Testing netinstall with GNOME desktop task selected
* User created during installation process
What was the outcome?
* User is member of: cdrom floppy audio dip video plugdev users netdev
scanner bluetooth lpadmin input
* The 'render' group exists (GID 992) but is completely empty
* Vulkan applications fail with errors like:
"Gdk-WARNING: Vulkan: Could not open device /dev/dri/renderD128:
Invalid argument (VK_ERROR_INCOMPATIBLE_DRIVER)"
This is quite weird as with a default installation (using systemd and
logind) a local user should have all the necessary rights and everything
should work out-of-the-box.
What outcome did you expect?
* Desktop users should be automatically added to the 'render' group during
installation, similar to how they are added to the 'video' group
* The 'render' group is required for GPU computing and Vulkan applications
to access /dev/dri/renderD* devices
[...]
Did you check that your user is properly opening a logind session (with
loginctl)?
Over the past few years, the trend has been to shrink the number of
groups set up via the installer, because other components can do that
automatically (and not just for the first user).
I'm cc-ing Laurent, who contributed such changes.
Yes I still think we have to many default groups already
