I managed to solve X server issue:

sudo apt-get update
sudo apt-get -y install build-essential
sudo apt-get install xvfb
sudo apt-get install xfs xfonts-scalable xfonts-100dpi

and then I run ebook-convert like this:

xvfb-run --server-args="-screen 0, 1024x768x24" ebook-convert myfile.pdf .mobi

But I still receives the same error.
Can somebody explain me what to do with it?

Regards,
Alex
