有人能告诉我如何让Xvfb处理32位色彩吗？例如，Vnc4server工作正常，但不符合我的目的。
> /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 - 它有效，而且：
> /etc/X11# Xvfb :1 -screen 0 1600x1200x32
Fatal server error:
Couldn't add screen 0
