libGL error: failed to load drivers iris and swrast in Ubuntu 20.04

I have a few problems (refer to messages below) with launching third party scientific softwares (e.g. coot, pymol or chimera).

I use the coot binary (0.9.5). Chimera is 1.14 build 42018. Ubuntu 20.04.2 LTS Gnome. I use the pymol-open-source from Github

Graphic card: VGA compatible controller: Intel Corporation UHD Graphics 620 (Whiskey Lake)
Model: Intel(R) Core(TM) i7-8565U CPU @ 1.80GHz

It seems that there are some problems with iris and swrast (please refer the message below).

I always get this message for chimera:

I got this message for pymol:

Thanks for the help.

I just had same issue with Kiwix on Linux Mint and found your question. I was able to solve my issue reading: https://github.com/kiwix/kiwix-desktop/issues/393. The issue I understood is that iris driver is configured on Ubuntu to be used by default on laptops whereas in my case on my old laptop graphic card supports older driver. So the solution/workaround is to set environmental variable before running the app in command prompt, like this:

MESA_LOADER_DRIVER_OVERRIDE=i965 ./kiwix-deskop

Hope that helps you too.

P.S. in case you want to try to set this variable permanently and nothing else breaks, see: How to permanently set an environment variable

I ran into a similar problem when trying to run a python app in a virtual environment (anaconda3). It turned out that the library libstdc++.so used by the virtual env was different from the one used by the OS.

I needed first to find out the full paths to libraries involved:

DISPLAY=:0 LIBGL_DEBUG=verbose python test.py

This gave me a hint that the libstdc++.so.6 used here might be different from the one used by OS:

libGL: MESA-LOADER: failed to open /usr/lib/x86_64-linux-gnu/dri/i965_dri.so: /home/fairfax/anaconda3/envs/py3/bin/../lib/libstdc++.so.6
: version `CXXABI_1.3.8' not found (required by /usr/lib/x86_64-linux-gnu/dri/i965_dri.so)

Then I checked out the library used by the virtual env:

strings /home/fairfax/anaconda3/envs/py3/bin/../lib/libstdc++.so.6 | grep CXXABI

To find out that the flag CXXABI_1.3.8 was indeed missing. I was able to fix this by overwriting the virtual env version with the system version of libstdc++.so.6 and redirecting all symbolic links to the new version:

$~/anaconda3/envs/py3/lib$ ls -al | grep libstdc++     
 lrwxrwxrwx  1 fairfax fairfax       19 lis  1 08:55 libstdc++.so -> libstdc++.so.6.0.25                                                
lrwxrwxrwx  1 fairfax fairfax       19 lis  1 08:55 libstdc++.so.6 -> libstdc++.so.6.0.25                                              
-rw-r--r--  1 fairfax fairfax  1594864 říj 29 16:27 libstdc++.so.6.0.25

On the package level this maybe fixed by installing single package:

sudo apt-get install libgl1-mesa-dri

Then about the packages:

• Pymol is packaged in Ubuntu with version 2.3.0, so it is installable by

  sudo add-apt-repository universe
  sudo apt-get install pymol
  

After many searches, I found a stack overflow post with more helpful answers for me at https://stackoverflow.com/questions/48453497/anaconda-libstdc-so-6-version-glibcxx-3-4-20-not-found

[Edit: OK, I solved my problem with the below steps, but now sometimes (not always!) when I run my python programs in this environment it gives the message free(): invalid pointer when my python program terminates, which is scary and undesirable. Though, it's a shorter error message so I'm keeping it for now :P]

Here's how I solved my problem:

1. I installed the latest version of gcc

conda install libgcc

After I tested it, it still didn't work for me, but maybe it will work for you.

2. I checked to see what kinds of linker files I had.

sudo find / -wholename "*conda*/**/libstdc++.so*"

Among other output files were the files (this environment is called moon)

/home/alex/miniconda3/envs/moon/x86_64-conda_cos6-linux-gnu/sysroot/lib/libstdc++.so.6
/home/alex/miniconda3/envs/moon/x86_64-conda_cos6-linux-gnu/sysroot/lib/libstdc++.so.6.0.26
/home/alex/miniconda3/envs/moon/x86_64-conda_cos6-linux-gnu/sysroot/lib/libstdc++.so
/home/alex/miniconda3/envs/moon/lib/libstdc++.so.6
/home/alex/miniconda3/envs/moon/lib/libstdc++.so.6.0.26
/home/alex/miniconda3/envs/moon/lib/libstdc++.so
/home/alex/miniconda3/envs/moon/lib/libstdc++.so.6.0.21

Before installing libgcc with conda, I only had the files

/home/alex/miniconda3/envs/moon/lib/libstdc++.so.6
/home/alex/miniconda3/envs/moon/lib/libstdc++.so.6.0.28
/home/alex/miniconda3/envs/moon/lib/libstdc++.so

You are supposed to have exactly 3 files that look something like this in your directory - there was a duplicate created for some reason.

I decided to try getting rid of all of the files that were similar to the old ones with

rm /home/alex/miniconda3/envs/moon/lib/libstdc++*

And after this, my error message disappeared.
