I had something similar a few months ago: https://lists.x2go.org/pipermail/x2go-user/2021-July/006579.html
Essentially, nvidia taking over libGL. I fixed it with (from the above post): Thanks Ulrich! > Yes indeed the system was using the libGL of nvidia. I did these steps to > recover the system: yum reinstall libglvnd* mesa* That fixes most of the symlinks of libGL in /usr/lib64 to again point to > the system's libGL. Except for this one: > # ll /usr/lib64/libGLX_indirect.so.0 > lrwxrwxrwx. 1 root root 26 Jul 1 16:03 /usr/lib64/libGLX_indirect.so.0 -> > libGLX_nvidia.so.470.42.01 So I did this: > # cd /usr/lib64 > # rm -f libGLX_indirect.so.0 > # ln -s libGLX_mesa.so.0.0.0 libGLX_indirect.so.0 > # ll /usr/lib64/libGLX_indirect.so.0 > lrwxrwxrwx. 1 root root 20 Jul 14 11:43 /usr/lib64/libGLX_indirect.so.0 -> > libGLX_mesa.so.0.0.0 Now glxinfo (and firefox) don't crash nxagent! > Not sure of the full implications of manually modifying that symlink.
