Rendering error

[flatmax]

Hi there,

I can't see alot of my included postscript images in LyX. A bounding box
appears, but no image.
I am running LyX version 1.0.4. On a Linux Debian system.

On the command line I get the following message :

Xlib: connection to ":0.0" refused by server
Xlib: XDM authorization key matches an existing client!
Error: Couldn't find per display information
GS [1642] error 256 E:1 1 S:0 0

Any help would be appreciated
Matt
