Summary0015996: Gnome session no longer works after updating mesa-libGL
DescriptionAfter updating our current CentOS server to the latest Centos 7.6 release GNOME3 sessions no longer work.
We use the mesa library for Gnome.
The mesa-libGL package was updated from version 17.2.3 to 18.2.5
Steps To ReproduceBefore update the mesa-libGL package contains
# rpm -ql mesa-libGL (version 17.2.3)

After updating to the latest version (18.0.5) it has changed to
# rpm -ql mesa-libGL

If I start the gnome-session-binary on the updated server I get
# /usr/libexec/gnome-session-binary
/usr/libexec/gnome-session-binary: symbol lookup error: /lib64/ undefined symbol: glXGetProcAddress

Something has definitively changed since as of mesa-libGL version 18. The has moved to the libglvnd-glx package but that does not contain the glXGetProcAddress function?
# rpm -qf /usr/lib64/
# nm -D /usr/lib64/ | grep glXGetProcAddress

while on a not updated server (versie 17.x of mesa-libGL)
# rpm -qf /usr/lib64/
# nm -D /usr/lib64/ | grep glXGetProcAddress
000000000001aea0 T glXGetProcAddress
000000000001aea0 T glXGetProcAddressARB

Apparently the function glXGetProcAddressmoved to /usr/lib64/ but the gnome-session-binary does not load it (see below)
# ldd /usr/libexec/gnome-session-binary | grep GL => /lib64/ (0x00007fd743fc3000) => /lib64/ (0x00007fd743731000) => /lib64/ (0x00007fd741eda000)
# rpm -ql libglvnd-glx
 # nm -D /usr/lib64/ | grep glXGetProcAddress
0000000000005d40 T glXGetProcAddress
0000000000006870 T glXGetProcAddressARB

I got it working by patching the gnome-session-binary but that's not ideal.

tar xvzf patchelf-0.9.tar.gz cd patchelf-0.9
src/patchelf --add-needed /usr/lib64/ /usr/libexec/gnome-session-binary
