 +If you want you can copy the libgl-xlib directory to some location of your likes and write a small wrapper "x2goglx" for starting GLX applications:
 +<code>
 +#!/bin/sh
 +LD_LIBRARY_PATH=<your directory>/libgl-xlib exec "$@"
 +</code>
 +
 +<code>
 +$ chmod u+rx x2goglx
 +$ x2goglx glxinfo

 +===== Matlab 2019b =====
 +
 +Compile like this:
 +<code>
 +meson -D glx=gallium-xlib -D gallium-drivers=swrast -D platforms=x11 -D dri3=false -D dri-drivers="" -D vulkan-drivers="" -D buildtype=release -D optimization=3 -Dprefix=/usr/local/mesa-20.1.0/
 +</code>
 +
 +To make Matlab load the new driver modify Matlab's lib search path:
 +cp $MATLAB_DIRECTORY/bin/.matlab7rc.sh ~
 +
 +Edit the file ~/.matlab7rc.sh, find the glnxa* section and add ''/usr/local/mesa-20.1.0/lib/x86_64-linux-gnu'' to LDPATH_PREFIX
 +
 +Add to your .profile: export MESA_GL_VERSION_OVERRIDE=3.0
