Cannot use terminal: no window contents

rstudio
#1

Terminal diagnostics gives my this (3 lines like this actually)

Handle: 'F06043A8' Caption: 'Terminal 1' Session Created: false

only the terminal tab is visible, but there is no content inside (no prompt, no way to type something)

Probably unrelated: When I start rstudio from the command line, I also get this error

rstudio
load glyph failed err=6 face=0xc21a40, glyph=2797
load glyph failed err=6 face=0xc21a40, glyph=2797

There is another post here, problem similar to mine (but my rstudio does not freeze).

I have the colorout package installed (useful when using R at the command line),
and my bash prompt is set by bash_it (an oh-my-zsh clone for bash) to

Sorry you are having trouble with the terminal. To try and figure out what's happening, can you try the following experiment:

In RStudio, close the Terminal tab (click the X on the tab itself).
Close RStudio and then restart it.
Tools -> Terminal -> New Terminal

Does that change anything? I suspect it won't but it's a good first thing to try. What does the Terminal Diagnostics show at this point?

I'll share some more things to try once we see what that does! Thanks for your patience and I hope we can get this figured out for you.

Thanks for trying to help me with this Starting-the-Terminal problem.

I work at two different PCs with nearly identical setup. Both rstudios had this problem, but only on one of them it goes away after a while. I don't know why, because I've observed this behaviour only twice, and realized it only much later after the error went away.

Maybe it has to do with doing a "Restart R Session" and repeatedly restarting an in- IDE webserver while working with the blogdown package. This package creates a preview of a blog post inside the RStudio IDE.

I didn't install blogdown on my work PC yet, where I wasn't able to get a terminal inside Rstudio.

Now here is the full output of Terminal Diagnostics when it's working properly:

Hi @GaryR

I experience a similar issue. The terminal panel is empty, no prompt appears.

I tried to close it, close RStudio, re-open it, close and restart individual terminals, to no avail.

Here is what the diagnostic shows:

Loaded TerminalSessions: 0

and my session_info():

Edit
Rstudio version is 1.1.383, I don't know why it shows up in @knb's session_info and not mine.

Try turning off all the following Terminal options, then opening a new terminal.

Local terminal echo
Connect with WebSockets
Save and restore environment variables

If that makes it work, then try to figure out which one(s) it was. The terminal is slower (typing lag) without websockets and local echo, so try turning them back on one at a time and opening a new terminal, etc.

#6

Thank you @GaryR !
That worked.
I turned back on "Save and restore varenvs" and "local terminal echo", so this works:

  • [x] Local terminal echo
  • [ ] Connect with WebSockets
  • [x] Save and restore environment variables

In case that matters, here is what Terminal diagnostic looks like now:
