[AUCTeX] Problem with Auctex Preview on Fedora

[Christophe FARGES]

Hello,

I'm using Auctex for quite a long time now on my personal laptop 
(cygwin+xemacs+auctex) and I especially like the preview option. At my 
office, we have received new computers (PC on linux fedora). I asked the 
team that manages the computers to install the latest version of auctex 
for Xemacs. It seems to be installed fine as when I open a TEX document, 
I have the LaTeX and Preview menus, etc... But when I try to preview the 
document, I get the following error:
" Display geometry unavailable: Symbol's function definition is void: 
display-pixel-width"
or:
"Symbol's function definition is void: previous-single-char-property-change"
The same document opens fine on my laptop.

My computer knowledge is quite low, but if you can give me some 
explanations on how to make it work, that would be fine...

Thanks a lot,
Christophe
