If we specify the full command everywhere then I think we have to include some section about merging them in case multiple things apply to a user. Tho I'm not sure if providing the full thing doesn't actually make it harder than providing a short guide on how to concatonate things with examples.

Also why are people too stupid to concatonate simple strings???

less things to to do for user - the better imo
alvr uses wide variety of users, from someone who has no idea what software is, to someone who writes code - and even they can be confused

giving them full guide how to concatenate multiple strings in specific way just because something has to be aligned like that is a way to make newbie user frustrated already

Sure, I just want to ensure that we don't cause more issues in case someone needs to apply more than one fix at a time. Because if you just tell them to "paste this" every time they'll either overwrite the other things or end up with multiple %command%s at once.

I'm pretty sure __VK_LAYER_NV_optimus=NVIDIA_only and VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json do the same thing in two different ways. I'd rather not have it twice if not actually necessary as it ends to rather long copy-pastes.

You could also extract the whole offload string into a separate variable if you're at it.

VK_ICD_FILENAMES would probably be the better way to fix this, only issue is when on some stupid distro that path doesn't match. And then we can just remove the vulkan layer. But we've already been emitting it like that and I've heard no real complaintd, so the path is probably fine.

Or rather a long while ago VK_DRIVER_FILES was introduced as a replacement for the icd env var, so we could also use that instead.

## Using ALVR with only integrated graphics

Beware that using **only** integrated graphics for running ALVR is highly inadvisable as in most cases it will lead to very poor performance (even on more powerful devices like Steam Deck, it's still very slow).
Don't expect things to work perfectly in this case too, as some older integrated graphics simply might not have the best vulkan support and might fail to work at all.

### SteamVR Dashboard not rendering in VR on Nvidia discrete GPU
If you encounter issues with the SteamVR dashboard not rendering in VR you may need to run the entire steam client itself via PRIME render offload. First close the steam client completey if you have it open already, you can do so by clicking the Steam dropdown in the top left and choosing exit. Then from a terminal run: `__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia steam-runtime`

## Wayland

When using old Gnome (< 47 version) under Wayland you might need to put `WAYLAND_DISPLAY='' %command%` into the SteamVR commandline options to force XWayland on SteamVR. This fixes issue with drm leasing not being available.
