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

$ export LIBGL_ALWAYS_INDIRECT=1
