Yes, you generate a new library by that. That library is pre-loaded to
your application and a) presents a newer OpenGL version to the
application and b) translates the OpenGL calls to X-Calls.

So yes to have to compile, but no to the first question on uninstalling?

Looks promising!

Yes I am prompted by Fedora to run this when I ran the meson command. But I'm still not following. I see here https://docs.mesa3d.org/gallium/drivers/llvmpipe.html

scons: *** No SConstruct file found.
File "/usr/lib/python3.8/site-packages/SCons/Script/Main.py", line 940, in _main

 Then:
Alternatively, you can build it with meson with:
mkdir build
cd build
meson -D glx=gallium-xlib -D gallium-drivers=swrast
ninja


So is this the meson command that I should replace with:
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

I still get ERROR: Must specify at least one directory name.
