Run RStudio server as non-root

RStudio IDE
,
#1

Since the new Electron rendering gives graphics glitches on my system, I'm trying RStudio server.

I installed rstudio-server-bin from AUR, and start the server with rstudio-server start.

It calls polkit to seemingly get root access.

In fact when I try rstudio-server status, it gives the following error:

[ABRIDGED] [118397]: WARNING Server user ' root' does not exist, running as root instead (not recommended); LOGGED FROM: virtual rstudio::core::ProgramStatus rstudio::server::Options::read(int, char* const*, std::ostream&) src/cpp/server/ServerOptions.cpp:282

How can I run the server as a regular user?

Just a thought before I turn in. Create an rstudio user, su and start & ?

RStudio Server is designed for multiple users -- it needs root access so it can process each users' login and load their data.

However with a little coaxing you can get it to run in single user mode. Here are the instructions from the admin guide -- though the guide is for Workbench, they'll work with the open source version too:

I think it already created a rstudio user for me, but it still shows this error in the logs of the service.

Thanks, but that doesn't work.

It doesn't start the server anymore.

Here are the logs:

I have commented out server-project-sharing=0 in /etc/rstudio/rserver.conf.

Then it complained about auth-pam-sessions-enabled=0 and I commented that as well.

Now it gives this error:

I'm also lost about those changes. Posit Workbench is the new name for RStudio?

@jonathan is there a solution?
