Describe the bug

I just installed a dedicated GPU for my Debian install into my server and tried to use the GPU inside the Ubuntu Focal workspace.
Everything seems to work, as example both nvidia-smi and glxheads show and use NVidia as the GPU, but things like Brave or OBS aren't able to detect it for some reason.

Running the following commands produces the following errors:
Brave: Doesn't start, only shows below error message. Without vglrun it starts, but of course without any acceleration, this aquarium test also doesn't work and shows "No WebGL support". /opt/VirtualGL/bin/vglrun -d "${KASM_EGL_CARD}" /opt/brave.com/brave/brave "\$@"

OBS: Starts and seems to detect the NVidia card just fine, adding a Browser source to this aquarium test works too and displays the fish, however going to "Output" only shows Software rendering as an option, not the NVidia card. /opt/VirtualGL/bin/vglrun -d "${KASM_EGL_CARD}" obs

Later down the line it shows this for ffmpeg:

error: os_dlopen(libnvidia-encode.so.1->libnvidia-encode.so.1): libnvidia-encode.so.1: cannot open shared object file: No such file or directory
info: FFmpeg VAAPI H264 encoding not supported
info: FFmpeg VAAPI HEVC encoding not supported

Not sure what I'm doing wrong, everything seems to semi-work fine but with a few hiccups :)

To Reproduce

Steps to reproduce the behavior:

Install GPU into Server + all drivers + NVidia Docker component
Enable GPU in Workspace
Run the above mentioned commands

Expected behavior Brave should start, OBS should find the GPU as an encoder
