Bug#878968: libglvnd0-nvidia: undefined symbol: _glapi_tls_Current makes system unusable

[Hendrik Tews]

Package: libglvnd0-nvidia
Version: 375.82-5
Severity: critical

Dear Maintainer,

after updating some packages this morning, X11 did not come up
any more and the system was completely unusable. Apparently gdm
was restarting continuously, making it impossible to enter
anything in a terminal window. I needed to boot in recovery mode
to get access again.

The syslog contains

    /usr/lib/gdm3/gdm-x-session[2703]: (EE) Failed to load /usr/lib/xorg/modules/extensions/libglx.so: /usr/lib/x86_64-linux-gnu/libGL.so.1: undefined symbol: _glapi_tls_Current

and I get the same undefined symbol error when I try startx.

After installing libglvnd0 (and purging libglvnd0-nvidia)
everything is fine again. In contrast to what is reported in
https://lists.debian.org/debian-kde/2017/10/msg00028.html, the
problem appears again, when I reinstall libglvnd0-nvidia.

Bye,

Hendrik
