When I ssh -X into my Ubuntu 18.04 desktop from my Mac OSX computer, I am able to get in. However, when I try to run firefox or rstudio, I get

libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

followed by

I know that there are issues with XQuartz in Mac (I am on Catalina), but are these issues on my Ubuntu Desktop or from Mac? I have the Nvidia 430 driver, I installed them again but the above error keeps appearing. Any help is appreciated. Thanks!

  • I get the error message in your first box when starting paraview plus omitted specifics. I have not found a fix for my case to offer, but I would suggest to take a look at this other answer https://askubuntu.com/a/566522/446253 for clues – XavierStuvw Nov 12 '19 at 14:03

    I have the opposite problem: the error pops up on my local computer, while the paraview program starts in full glory when I log in via ssh -YC .... So this appears to depend on local configurations, not on the program itself. Added to offer another clue. – XavierStuvw Nov 12 '19 at 14:10

    I figured it out, it was because XQuartz doesnt have support for the nvidia driver. When you tunnel in, it will show that the default set of drivers is actually not my nvidia driver – user321627 Nov 12 '19 at 17:42
  • What do you mean by "tunnel in"? How did you solved the issue? – KcFnMi Feb 20 '20 at 04:38

I got same error when using gnuplot. The reset of environment variable works for me:

$ export LIBGL_ALWAYS_INDIRECT=1

The solution comes from: https://psycomp.utsc.utoronto.ca/support/index.php/2021/10/14/libgl-error-when-using-ssh-x-forwarding-with-macos/
