I have set this up and it appears to be working, except the images it produces are anything but nice.
Where am I going wrong? Is there something else I need to install? I am using Xvfb as you suggest in your FAQ
It seems that Xvfb is starting with 4 or 8 bit color depth.
Maybe you need to start Xvfb with an explicit color depth:
Xvfb :1 -screen 0 1600x1200x32&
Unfortunately Codefisher's image disappeared from the web, but I have the feeling I may just have the same issue here. Take a look at my wiki:
I tried the above mentioned solution, but it fails:
Xvfb :0 -screen 0 1600x1200x32
Fatal server error:
Couldn't add screen 0
Same goes for :1 or :2
Update: setting bits to 24 makes Xvfb start, but the colors and fonts are still suboptimal.
Xvfb :0 -screen 0 1600x1200x24
