[SOLVED] Ubuntu 20 with Intel Graphics 620 OpenGL not installed

rmfrank · 05-12-2022, 07:04 AM

Hi everybody,

I have an rather old PC (fan-less - thus very interesting) onto which I need to install the OpenGL software in order to run several programs.
However, no matter what I've tried (c.f. below), inxi -G always shows 'OpenGL: renderer: N/A v: N/A'.
I've
- updated to the latest 20.04LTS release
- tried installing the OpenGL tools (which should load OpenGL)
- adding specific repsoitories (intel graphics for mesa and kisak-mesa)

I've found several hints and have tried most of them, but I simply can't get any OpenGL to load. Others seem to be able to do so - so what am I missing?

Thanks in advance
Robert

Mesa?

If you mean that's what's missing: I have installed several mesa versions, none changed anything.

Mesa provides the /usr/lib(64)/libGL* libraries. Use the latest distro version.

Also, if you've had a proprietary video driver there, they may well have replaced the symlinks to the Mesa libraries with symlinks pointing at their own versions. Here's what a pure Mesa version looks like:

Code:

-rwxr-xr-x 1 root root 703K May  1  2021 /usr/lib64/libGLdispatch.so.0.0.0*

Andthere should be none of these modules blacklisted.

I installed all latest packages of the Ubuntu20.04LTS. And, as mentioned, tried several other mesa repositories too.
I have nothing in /usr/lib64 and no libGL* in /usr/lib - is your listing for Ubuntu20.04LTS?

dpkg -l | grep mesa shows:

no mesa module is blacklisted, but also not loaded - however, that's the same for other similarly set up machines.

business_kid · 05-13-2022, 01:12 PM

My listing was from Slackware. That supplies full packages, each with includes all libs, docs, and whatever's in /usr/share. Ubuntu has each package like Mesa split up into an unknown number of packages.

So I know where I stand. You don't. Try

Code:
```
dpkg -l |grep libGL
```
??
Or run updatedb and go looking for libGL with locate.
have a look at /etc/ld.so.conf, which should list directories with system libraries, and check in each of those
Otherwise google the problem.

Lots of different Intel GPU models provide UHD Graphics 620. Which is yours? It might matter. inxi -Ga would indicate.

Getting OpenGL to work in Focal with Intel graphics should be automatic. Except for pci=noaer in Grub's linu lines, I didn't do anything special:

Do you not have

rmfrank · 05-16-2022, 02:08 AM

OK, guys this is a pebkac ! I was connecting to the machine via SSH from my working place using -Y. This obviously doesn't do what I expected. When using the inxi command in a terminal after logging in with the GUI, the OpenGL driver is correctly shown.
