We install RStudio for our users to run interactively on our HPC clusters, via remote sessions, either via X forwarding or remote desktop like FastX or TurboVNC. The hardware OpenGL mostly does not work in these situations, so, we want to make the desktop.renderingEngine=software a global option, that is, make it valid for all launches of RStudio regardless of what an user has in their ~/.config/RStudio/desktop.info. By experimentation I found that setting the RSTUDIO_CHROMIUM_ARGUMENTS="--disable-gpu" by itself does not fix the OpenGL launch problems.
Is there a global configuration file where we could put this setting? I have been searching around and can't find any information about that.
