The isue is that the swrest cant be found although i have ensured that the library directory is specified in the ld conf. For some reason the linker still looks for swrast in usr/lib/dri although the file is in /usr/lib/x86_64-linux-gnu/.

The worst part is that i cant change the behaviour. Ive made sure that the directory of swrst is specified in the dynamic linker folder.

The problem orignates from error involving libGLU.so.1, while running a Python script that imports gmsh and dolfinx in a WSL Ubuntu environment. I solved initial problem by manual instalation of:

libglu1 \
libxcursor-dev \
libxft2 \
libxinerama1 \
libfltk1.3-dev \ 
libfreetype6-dev  \
libgl1-mesa-dev \
libocct-foundation-dev \
libocct-data-exchange-dev 

according to original post: https://fenicsproject.discourse.group/t/oserror-libglu-so-1/6021 although that error on its own is bizzare and should not have been a problem in the first place.
After resolving the libGLU.so.1 starting gmsh now results in the swrast error

@deadP1rx /usr/lib/x86_64-linux-gnu path is added automatically by the glibc package. Check /etc/ld.so.conf.d/x86_64-linux-gnu.conf for details. And glibc is part of your system installation. Unless you messed with your linker's search paths there's no need to add this directory manually. Try running glxinfo -B and see if the command works, to give you info about your dri setup. Also, run ldconfig -v /usr/bin/gmsh to see what's missing preventing your app to start.

On Ubuntu 22.04 with radeon driver gmsh-4.8.4 starts okay:

hey, thx for the answer.
The x86_64-linux-gnu.conf file contains

# Multiarch support
/usr/local/lib/x86_64-linux-gnu
/lib/x86_64-linux-gnu
/usr/lib/x86_64-linux-gnu

Ive created additional local file that specifies /usr/lib/x86_64-linux-gnu/dri but u r right that it might not be necessary, but I am quite desperate at the moment. I ve previously checked with ldconfig -p | grep swrast if the library appears in the cache but it returns nothing.

Basic GLX info looks fine, it specifies device, opengl version etc..

The gmsh works fine in the python environment. Apparently the problem is just with the GUI.

I tried also running pyvista for mesh visualisation with ipywidgets with trame but that explodes kernel every time i call the plot, func, even for simple examples. So i guess that the problem affects all graphics based processes (assuming that those errors are connected)

All that is quite unique behaviour, and i have not seen anything like that before
