[Cin] Problem with X11-OpenGL

[Andrea paz]

I have tried to explore your suggestions, but I don't think I am able
to implement them.

GLVND:

glvnd is a vendor neutral libgl library that was made by nvidia so
that nvidia proprietary drivers can co-exist with mesa on the same
system. The use-case for this is usually desktops or laptops with an
intel iGPU and an nvidia dGPU. If you are running intel/amd or all
amd, you don’t need libglvnd.

Here is a patch to compile mesa-git without glvnd:
https://www.reddit.com/r/archlinux/comments/hwhouh/how_to_build_mesa_without_libglvnd/

Manually:

    PART 3: Compiling mesa-git without libglvnd

I have two of my own gitlab repositories that makes this easy to do.

First let’s clone them:


git clone http://gitlab.com/gloriouseggroll/mesa-git-noglvnd
git clone http://gitlab.com/gloriouseggroll/lib32-mesa-git-noglvnd

Now lets make both packages:


cd mesa-git-noglvnd
makepkg
cd ../lib32-mesa-git-noglvnd
makepkg

They need to be installed at the same time, which is why we compiled
them both first. Now lets move them to the same folder and install
them:


cp *.pkg.tar.xz ../mesa-git-noglvnd/
cd ../mesa-git-noglvnd
sudo pacman -U *.pkg.tar.xz

When you do this, it’s going to ask you to replace vulkan-radeon
and/or vulkan-intel packages, as well as remove libglvnd. This is
because mesa-git provides all of those when compiled from this
package, libglvnd being replaced with mesa’s libgl. If compiled from
the AUR, it replaces just the vulkan packages.


It says here that there might be problems by not installing glvnd and
so the best solution is to create a glvnd installation-fake:

I don't understand how to do all these things. Also, I used mesa-git
in the past but had so many problems that I didn't want to put it
back.


ZINK:

I tried this:
__GLX_VENDOR_LIBRARY_NAME=mesa MESA_LOADER_DRIVER_OVERRIDE=zink
GALLIUM_DRIVER=zink /home/paz/cinelerra5/cinelerra-5.1/bin/./cin

CinGG starts but with the following errors:

$ __GLX_VENDOR_LIBRARY_NAME=mesa MESA_LOADER_DRIVER_OVERRIDE=zink
GALLIUM_DRIVER=zink /home/paz/cinelerra5/cinelerra-5.1/bin/./cin

Instead starting without Zink's environment variables I get the only,
usual, error:

BC_DisplayInfo::gl_fb_config failed

In both cases X11-OpenGL does not work.

I couldn't find any other info on getting Zink to work.
