I;m trying to run untitests for my PyQt5 application on Jenkins.

I've setup job and configure Xvfb with option +extension RANDR

Here is output of starting Xvfb:

Xvfb starting$ Xvfb -displayfd 2 -screen 0 1280x1024x24 -fbdir /var/lib/jenkins/2014-08-27_00-24-501722001619127938033xvfb +extension RANDR

But my gui tests fail with Xlib: extension "RANDR" missing on display ":1".

How can I fix this? Is there any other way to run PyQt5 GUI unittest?

I've looked at this question, but it didn't help

I'm using ubuntu 14.04.1 x86_64; python3.4

  • error if for display `:1` and your shell command is for `fd 2` and `screen 0`, is there perhaps a mismatch here? – Dima Tisnek Aug 27 '14 at 14:40
  • No, I've tried to start test with manual start Xvfb with default parameters plus RANDR exception and get the same error on display :99 – Nikolai Golub Aug 27 '14 at 19:21
  • What is value of `DISPLAY` when you run the unit tests? Does the order of parameters to `Xvfb` matter? That `SocketCreateListener() failed` error, perhaps there's another X server running already or something? – hyde Aug 27 '14 at 21:01
