Description Stefan Becker 2016-11-05 18:57:56 UTC
Description of problem:

On my system with xorg-x11-drv-nvidia (rpmfusion) GLX stopped working after the latest updates which introduce a dependency on libglvnd (Fedora). The problem is that GL code loads /usr/lib64/libGL.so.1 (mesa) instead of /usr/lib64/libglvnd/libGL.so.1 (libglvnd).

Version-Release number of selected component (if applicable):
libglvnd-0.2.999-4.git295e5e5.fc24.i686
libglvnd-0.2.999-4.git295e5e5.fc24.x86_64
xorg-x11-drv-nvidia-libs-367.57-3.fc24.i686
xorg-x11-drv-nvidia-libs-367.57-3.fc24.x86_64

How reproducible:
always

Steps to Reproduce:
1. glxinfo (dumps error message about failing driver load of "swrast")
2. ldd $(which glxinfo)
3.

Actual results:
$ glxinfo
name of display: :0
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
X Error of failed request:  GLXBadContext
  Major opcode of failed request:  153 (GLX)
  Minor opcode of failed request:  6 (X_GLXIsDirect)
  Serial number of failed request:  48
  Current serial number in output stream:  47
$ ldd $(which glxinfo)
        linux-vdso.so.1 (....)
        libGL.so.1 => /usr/lib64/libGL.so.1 (....)
$ rpm -qf /usr/lib64/libGL.so.1
mesa-libGL-12.0.3-2.fc24.x86_64

Expected results:
$ glxinfo
name of display: :0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
....
$ ldd $(which glxinfo)
        linux-vdso.so.1 (....)
        libGL.so.1 => /usr/lib64/libglvnd/libGL.so.1 (....)
$ rpm -qf /usr/lib64/libglvnd/libGL.so.1
libglvnd-0.2.999-4.git295e5e5.fc24.x86_64

Additional info:
I fixed this by adding ld.conf.so.d files for libglvnd:

# ls -lht /etc/ld.so.conf.d/libglvnd-lib*
-rw-r--r--. 1 root root 20 Nov  5 20:28 /etc/ld.so.conf.d/libglvnd-lib64.conf
-rw-r--r--. 1 root root 18 Nov  5 20:28 /etc/ld.so.conf.d/libglvnd-lib.conf
# cat /etc/ld.so.conf.d/libglvnd-lib64.conf
/usr/lib64/libglvnd
# cat /etc/ld.so.conf.d/libglvnd-lib.conf
/usr/lib/libglvnd
# /sbin/ldconfig

After that GLX started to work and I got my X11 login screen back...

Comment 1 Stefan Becker 2016-11-05 21:31:06 UTC
https://bugzilla.rpmfusion.org/show_bug.cgi?id=4303#c35 seems to indicate that there should be a symlink /usr/lib64/nvidia/libGL.so.1 => ../libglvnd/libGL.so.1 instead. If that is the correct solution then the bug would be in xorg-x11-drv-nvidia-libs.

Hmmm....

# ls -lht /usr/lib64/nvidia/libGL.so.1
ls: cannot access '/usr/lib64/nvidia/libGL.so.1': No such file or directory
# rpm -ql xorg-x11-drv-nvidia-libs.x86_64 | fgrep libGL.so.1
/usr/lib64/nvidia/libGL.so.1

# ls -lht /usr/lib/nvidia/libGL.so.1
ls: cannot access '/usr/lib/nvidia/libGL.so.1': No such file or directory
# rpm -ql xorg-x11-drv-nvidia-libs.i686 | fgrep libGL.so.1
/usr/lib/nvidia/libGL.so.1

I wonder what went wrong during the package installation...

Comment 2 Stefan Becker 2016-11-05 21:35:58 UTC
Problem got fixed by "dnf reinstall xorg-x11-drv-nvidia-libs":

# ls -lht /usr/lib/nvidia/libGL.so.1
lrwxrwxrwx. 1 root root 22 Oct 25 17:18 /usr/lib/nvidia/libGL.so.1 -> ../libglvnd/libGL.so.1
# ls -lht /usr/lib64/nvidia/libGL.so.1
lrwxrwxrwx. 1 root root 22 Oct 25 17:18 /usr/lib64/nvidia/libGL.so.1 -> ../libglvnd/libGL.so.1


Can it be that the order of the package install libglvnd, then xorg-x11-
drv-nvidia-libs is important for symlinks from the later package to be installed correctly?

Closing as NOTABUG

Comment 3 Stefan Becker 2016-11-05 21:37:11 UTC
Forgot to add:

$ ldd $(which glxinfo)
        linux-vdso.so.1 (....)
        libGL.so.1 => /usr/lib64/nvidia/libGL.so.1 (...)
