Debian 9: glxgears:i386 on 64 bit system.

Postby frank38 » 2017-10-30 12:17

Hi,
I'm trying to get glxgears @ 32 bit working on my 64 bit installation.
My graphic card is Nvidia, and I'm using the proprietary drivers.
I think I've installed all the 32 bit packages required by that program, but
glxgears do not work, I only get this message:
Error: couldn't find RGB GLX visual or fbconfig
The same error with glxinfo.
I don't know what's wrong.

Do amd64 glxgears and glxinfo work ?
Doesn't the proprietary driver require a specific version of mesa-utils ?

Both glxgears and glxinfo @ 64 bit work, games @ 64 bit too.

Please expand on the above.

What command are you using to launch the 32 bit version of glxgears on 64-bit?

You must first add the i386 architecture to the repos, update them, and then install the packages you need, as explained in the official Debian Wiki.

I was more hoping for a list of what i386 packages you added, the confirmation with "apt policy" that they are installed, and the command you are using to try and run the 32-bit version, since I already have a similar working setup and can also try it.

Why? Glxgears has been obsolete for years. It was replaced by glxinfo. Other than watch the pretty gears go around (which was mesmerizing I admit) glxgears was not very useful.

Edited to add: Benchmarking

I just added a much better benchmark, glmark2 2017.07 for Stretch in my multimedia OBS repo. It's in Ubuntu but not Debian, so I adapted the older Ubuntu /debian folder for the newer release on Debian by cutting out all the Mir crud. At least the rotating thingies and the jellyfish are nice-looking. I'll also add virtualgl, which provides the glxspheres benchmark.

It won't build on vanilla Jessie, but should if you upgrade to the newer Mesa in jessie-backports.

Glxgears is the most simple program to check the 3d funtionality on my machine. I'm not interested in any benchmark. At the moment I have no working 3D with program @ 32 bit.
Some help?

Since I've asked twice for some information and you've just responded with irrelevant asides about glxgears, no help.

Because you have an Nvidia GPU, you should install libgl1-glvnd-nvidia-glx and libglx0-glvnd-nvidia and all the dependencies, and also libglew needed by glxgears@32 bit.

How to add the i386 repos: https://wiki.debian.org/Multiarch/HOWTO

dpkg --add-architecture i386
apt-get update
apt-get install package:i386

When you install the nvidia proprietary drivers, it is asked at some time if you want the 32 bit version of the driver along with the 64 bits. You should say yes.
I don't know how it is for the ones provided by debian.

You see, when you refuse to answer simple diagnostic questions, very few volunteers here feel like helping you, buddy. It's odd how that works, innit?

Anyway, go here: https://sourceforge.net/projects/virtualgl/files/2.5.2/

install the i386 virtualgl deb package.

Run "glxspheres".

Done.
