Comment # 17 on bug 1034343 from Andrei Dziahel

All right, I've played with the 381.89 installer a bit, namely with
./libglvnd_install_checker/check-libglvnd-install.sh and for me it fails on the
same stage as Michal. Before testing all that I've uninstalled nvidia driver,
reinstalled Mesa-related packages and libglvnd* packages

running sh -x check-libglvnd-install.sh revealed that it failed at
`check-entrypoint libGLdispatch.so libGL.so.1`. `ls -l /usr/lib64/libGL.s0*`
showed libGL.so is a symlink to libGL.so.1.0.0, but libGL.so.1 is a symlink to
libGL.s0.1.2.0. running `ln -sf libGL.so.1.0.0 libGL.so.1` apparently made
installer happy since the subj error gone away and the driver has been
installed without a hitch. Unfortunately it resulted in gdm being unable to use
GLX� and thus unable to start, and this is where I've became out of time and
and reinstalled the driver overwriting the libglvnd.

I have also noticed that `rpm -V libglvnd0` reports `....L..
/usr/lib64/libGL.so.1 ` out of the box (before messing with symlinks)  and I
have no idea why and whap proper value should be. 

Not sure that would, yet still hope that helps.
