Quoting: natis1For starters, Gentoo includes git versions of all packages in its repos so no need to git clone, ./configure, make, make install anything manually. Arch does something similar with its aur.

More importantly though, when you build a package from source using a git repository as the source on Arch that package is tracked by your package manager and can be updated along with the rest of your system (pacaur -Syu --devel). As far as I know, Debian and variants lets you build a package from source, but doesn't automatically keep it up to date. If you install Mesa git but never update it it will quickly fall behind the fixed release version.

I see. But all those methods install Mesa as a replacement for stable one. That's not the goal for me in this case. I like to have experimental / master Mesa alongside stable one, and only use it on demand when needed. So in such case building it and placing it in custom location works best.

Here is an example how to do it: https://www.gamingonlinux.com/wiki/Building_Mesa_from_source

So are you just launching with an LD_PRELOAD? Or do you change the .desktop file? I was going to ask about steam command parameters, but I don't think you use it due to DRM, right?

Quoting: slaapliedjeWell, the open source driver went through many names / iterations. radeon, radeonhd, radeonsi, radv, etc. Nvidia has had nv, nouveau.

I think you are mixing up kernel driver (radeon / amdgpu), and API implementations (radeonsi/r600 for OpenGL, radv/amdvlk for Vulkan and etc.). Having different names is quite reasonable, if they have actually different code for different hardware, or simply different implementations.

Oh, actually I was thinking of xorg drivers. But yeah they split them up into multiple kernel modules/xorg drivers. Instead of just 'radeon'.

I'm using LD_LIBRARY_PATH and a bunch of variables needed for OpenGL and Vulkan custom locations. See in the linked wiki page. I'll update it soon and will also put my common scripts somewhere so you can see examples.

I.e. I made a script mesa_run.sh which launches its parameter with custom mesa, and I simply use that when I want to run something using that custom Mesa, rather default system one. You surely can use the same idea in desktop launchers and other scripts.

Example of how you can do it (assuming you put your mesa in /opt/mesa-${branch})

mesa_run.sh

#!/bin/bash

export mesa_dir=${mesa_dir:-"mesa-master"}

if [[ "$1" == "32" ]]; then
   arch_dir="x86"
   vk_arch="i686"
   shift
else
   arch_dir="x86_64"
   vk_arch="x86_64"
fi

mesa_env="LD_LIBRARY_PATH=/opt/${mesa_dir}/${arch_dir}:$LD_LIBRARY_PATH LIBGL_DRIVERS_PATH=/opt/${mesa_dir}/${arch_dir} EGL_DRIVERS_PATH=/opt/${mesa_dir}/${arch_dir} VK_ICD_FILENAMES=/opt/${mesa_dir}/${arch_dir}/radeon_icd.${vk_arch}.json"

echo "Mesa env:"
echo "${mesa_env}"
echo "==========================================="

export ${mesa_env}
$@

I updated the wiki, and put the build script here: https://gist.github.com/shmerl/f4e5f76871239158cf083e37c5da56f4

You need to add System 76's "Pop!_OS", and the NVIDIA GeForce 920MX; both are it is missing from the computer specifications.

Quoting: ShmerlWhat was the last AMD card you used? I was Nvidia user for a long time, but got fed up with poor integration and need to use the blob, so I switched to Polaris a while ago (RX 480). It's been a breeze since.

AMD RX 460 was the last card I used.

Quoting: SinaCutieAMD RX 460 was the last card I used.

That's strange, since Polaris is quite well supported. I didn't have any major issues with RX 480. What exactly was the problem with your card?

I still use 970 with nvidia binary driver. It works. I don't have tearing etc. To those saying about compiling from source, if we want an upturn in the amount of Linux users we need to make this unnecessary. Sure we can all do these tasks but many will balk at this task and go back to windows.

Compiling for new users is really annoying when for this users must be only download and install (ppa is acceptable)
