Fistly, there are slots only when tasks are running.
Secondly, stderrgfx.txt files are created when you launch graphics application.

I tried opening boinc and all of the stuff you said, but still the slots folder is empty. I really cannot understand what's going on: what am I missing?

In my case the folder "slots" is in my home directory. Maybe the folder is defined during installation. In my case Rosetta 4.15 works with graphics and so the file /slots/0/stderrgfx.txt is empty.

I had to install a few packages (also 32 bit packages although 64 bit OS) in order to get the graphics work, but forgot which packages. Maybe try packages that are recommended here (of course use maybe different package names on different linux distributions):

Do you have error messages in the cmd terminal when you click "show graphics"?

I have this problem too.

The slots/0:

slots/1,2,3 more or less similar

This thread is about problems when showing the graphic for a task. The error you show does not look like the program that is used to show the graphic. So I believe you are having some different issue. Please describe it further in a new thread. Do you have any work running now? How many of those 35 second waits do you have? Any recent changes to your BOINC version or system in general?

Blank graphics on linux...

Would you add the boinc group to your userid and try the graphics. You might have to log out as well.

The command should be something like sudo usermod -aG boinc

Hi guys, same issue here. Ubuntu 20.04 LTS. Graphics is totally blank with just the outlines. I have already added my user to the boinc group. Any help is appreciated
