I updated my TW system to the G05 series from the nvidia repository.
After that, SDDM wouldn't start anymore, leaving me only with a black screen
and mouse cursor.  The logfiles revealed the greeter couldn't create an OpenGL
context.
So I activated autologin for sddm, so I could work, and next noticed that I
cannot use accelerated glx stuff.  

After a *lot* of hunting around and comparing with the old, still working
snapshot, I realized that the update had removed the file
/usr/lib/tmpfiles.d/nvidia-logind-acl-trick.conf that created neccessary links
in the uaccess part of the /run filesystem, so that systemd-logind would allow
access to the /dev/nvidia* files.

I noticed the file is still mentioned in the postuninstall scripts section of
nvidia-gfxG05-kmp-default:
lux:~% rpm -q --scripts nvidia-gfxG05-kmp-default | grep -B 1 acl-trick
    # cleanup of bnc# 1000625
    rm -f /usr/lib/tmpfiles.d/nvidia-logind-acl-trick.conf

But nothing seemed to have created it when installing the package :(

The BNC thread is quite old - is this still the official method to get access
to the device files, or did I miss some change?
