For anyone toying around with proprietary Nvida on Trixie Stable
I'm here to save you some time, wish I found this forum thread earlier

>The driver doesn’t replace the X server’s libglx.so anymore, so that module should come from your distribution’s Xorg packages. libglxserver_nvidia.so is a separate file.
Fix for me was
sudo ln -s \/usr/lib/xorg/modules/extensions/libglxserver_nvidia.so.595.71.05 \/usr/lib/xorg/modules/extensions/libglxserver_nvidia.so
I otherwise have a very plain, very boring Trixie Stable setup with no backports/etc. only thing not from the stable repo is Nvidia 595 and it's pretty good here on KDE Plasma / X11 so far across Unity, UE4, and UE5 titles.
