How to enable gpu sandbox with nvidia driver ?

[userrand]

Additional feature, program, sandbox permission, etc

Is it possible to add an option to enable the gpu sandbox even if one has an nvidia driver ? I am not sure why it is disabled but I would like to enable it to see if obsidian still works well with it enabled.

@userrand Disabling the GPU sandbox is common among Electron applications running on Wayland with Nvidia GPUs:

That being said, it might no longer be necessary to have an Nvidia-specific code path with newer driver versions and newer Electron versions:

If you have time, please test Obsidian launcher arguments to see how well Obsidian behaves, like so:

$ flatpak run --nosocket=x11 --socket=wayland --command=zypak-wrapper md.obsidian.Obsidian /app/obsidian --ozone-platform-hint=auto --enable-features=WaylandWindowDecorations --enable-wayland-ime

@joshua-stone the computer I tested that on has both an amd and a nvidia gpu.

I tested :

• scrolling through a file with vim ( the scrolling was done with a community theme enabled if that is useful)
• opening a file with the quick switcher
• looking at nodes in graph view with a trackpad
• looking at the result of a dataview query

I did not see any rendering or slowing down issues but maybe that is because it is using the amd gpu rather than the nvidia gpu (which maybe ideally one would add an exception for computers that have both if the computer uses mainly the amd gpu)

@userrand Can you test this build?

$ flatpak install --user https://dl.flathub.org/build-repo/116527/md.obsidian.Obsidian.flatpakref
$ flatpak run --user --nosocket=x11 --socket=wayland md.obsidian.Obsidian//test

@joshua-stone I have not tested the build but I am not sure if my experience would be representative of most nvidia users as I would expect that the nvidia driver on the computer only gets used for intense gpu calculations like gaming, 3d modeling or neural network related computations. As such, changing the code based on my experience might lead a lot of people with nvidia gpus to have issues with the obsidian flatpak.

@userrand I've merged the changes to the script Nvidia has significantly improved Wayland support and Discord doesn't appear to have experienced major regressions since dropping Nvidia-specific arguments.

If anyone reports regressions, then I'll revert these changes.
