[Documentation] Mention `prime-run`; raw variables are unwieldly #243

Open MilesBHuff opened 3 years ago

MilesBHuff commented 3 years ago

Request to mention the existence of prime-run, which is a script that comes with nvidia-prime.

Currently, the documentation says this:

Vulkan applications must be launched with __NV_PRIME_RENDER_OFFLOAD=1 to render on the dGPU. GLX applications must be launched with __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia to render on the dGPU.

While true, this is highly unwieldly for commandline users. Adding the following line to the above would help usability significantly:

The prime-run script included with nvidia-prime sets these variables for you; meaning you can simply run prime-run $APP to start an application with the dGPU.

Issue implemented in PR #244.

system76-power conflicts with nvidia-prime, so it can't be installed. That package cannot be recommended.

I would rather just state that a script can be used to set these variables for convenience.

Interesting. On Arch/Manjaro, there is no such conflict, so I actually have prime-run available. Maybe the AUR package needs to be updated to indicate that nvidia-prime and system76-power should not be co-installed?

Here's an idea: what if system76-power bundled prime-run?

@MilesBHuff The prime-run command in Arch is just those commands in a script. See the following: https://github.com/archlinux/svntogit-packages/blob/packages/nvidia-prime/trunk/prime-run from https://archlinux.org/packages/extra/any/nvidia-prime/. I think talking about the AUR is kind of unrelated to Pop!_OS as well.

Right -- I was under the impression that that's what prime-run was everywhere. If it isn't, then maybe System76 could provide its own wrapper script with those variables. It's certainly handy to have!

Fwiu, System76 actually maintains its own PKGBUILDs for the AUR; so while it's not related to Pop!_OS, it is related to system76-power.

We do not maintain anything related to Arch. Packages on AUR are not maintained by us, and we do not provide the PKGBUILD for them.

Thanks for clarifying! I must have misread somewhere. I remember being surprised at the time, since I'd figured you'd only be supporting Pop!_OS.
