[Jaakan Shorter]

Public bug reported:

how to reproduce the issue

1. clean install of Ubuntu 23.10 on something like a Dell Optiplex 5050 + GTX 1650
2. make sure nvidia-driver-535(proprietary, tested) is installed and active
3. install Blender 4.1.1 from Snap
4. open Blender and go to the GPU settings, GPU should be listed 
5. update to current patch level IE update-manager ( reboot )
6. upgrade to 24.04 via update-manager -d ( reboot )
7. open Blender and go to the GPU settings, GPU should be missing

to fix

1. switch to nouveau ( reboot )
2. switch back to nvidia-driver-535(proprietary, tested) ( reboot )
3. open Blender and go to the GPU settings, GPU should be listed 


Dell Optiplex 5050 ( GF's daughter's computer, she uses for Blender 4.1.1 ) 
I7-7700
GTX 1650 + nvidia-driver-535(proprietary, tested)
was on Ubuntu 23.10

Did an update-manager -d to 24.04 and everything seemed to go smoothly.
I opened Blender 4.1.1 and it couldn't find the GPU. I had to switch to
nouveau, reboot, switch back to nvidia-driver-535(proprietary, tested),
and reboot and Blender 4.1.1 could find the GPU again.

I did the same on my computer

Custom PC
i5-12400F
Arc A750 + intel's Ubuntu Repo
was on Ubuntu 23.10 

Did an update-manager -d to 24.04 and everything seemed to go smoothly
too. I opened Blender 4.1.1 and it couldn't find the GPU. I tired older
versions no luck. reinstalled all the packages from intel no luck. this
might be partly an intel issue so I posted in their community too
