We just upgraded Connect from v1.6.10-3 to v22.214.171.124-7 and I'm seeing the following warning in the logs.
"In grDevices::png(f) : unable to open connection to X11 display ''
This issue seems to be the same thing that was reported here for shiny server:
I also saw this old post that makes me wonder if we need pango? https://support.rstudio.com/hc/en-us/community/posts/200642948-RStudio-Server-unable-to-open-connection-to-X11-display
With this upgrade we explicitly installed both R 3.4.4 and 3.5.1 built from source using https://cran.r-project.org/src/base/R-3/R-3.4.4.tar.gz and https://cran.r-project.org/src/base/R-3/R-3.5.1.tar.gz whereas previously only R 3.4.4 was installed via install r-base in the setup.
I looked through the documentations and didn't seem to find anything related to this error or pango but maybe I missed something in the documentation. Thoughts appreciated, thanks!
