How to get Xvfb to work on 32 bit color

Question

Can anybody tell me how to get Xvfb to work on 32bit color? Vnc4server works fine for example, but didn't fit my purpose.

> /etc/X11# Xvfb :1 -screen 0 1600x1200x24
error opening security policy file /etc/X11/xserver/SecurityPolicy
(EE) XKB: Couldn't open rules file /usr/share/X11/xkb/rules/base
Could not init font path element /usr/share/fonts/X11/cyrillic, removing from list!
[config/hal] couldn't initialise context: (null) ((null))
FreeFontPath: FPE "/usr/share/fonts/X11/misc" refcount is 2, should be 1; fixing.

Aka - it works, while:

> /etc/X11# Xvfb :1 -screen 0 1600x1200x32
Fatal server error:
Couldn't add screen 0

Answer 1

32 is no valid depth, see this bug report

Try this instead: Xvfb :1 -screen 0 1600x1200x24+32
