Using PyQt4.QtWebKit on a Debian server

Question

I'm having a problem using PyQT4 on a Debian server. My script works fine on an Ubuntu Desktop machine, and I now want to deploy it on a server.

Knowing it needed an X server, I launched one doing

vncserver --display 800x600 :4242

I then exported the display :

export DISPLAY=:4242

But my program keeps returning the error

cannot connect to X server :4242

Any idea ?

Answer 1

It's not --display, it's -geometry.

I would guess you don't have the rights to connect to the vncserver. It was already running, wasn't it ? Try running another instance.

Answer 2

Instead of using vncserver, you could use (at least on Debian) xvfb - Virtual Framebuffer 'fake' X server.

After installing this package simply run:

$ xvfb-run python your_script.py
