Problem with X.org server, NeoMagic driver and Citrix client

[Michael Marte <informarte@freenet.de>]

Hello *,

my employer runs a Citrix server for home workers. However, the Citrix 
server only offers connections with color depth 8 while my X server uses 
color depth 24 by default. Now, when the Citrix client opens a window, a 
gray rectangle is displayed the first third of which contains the window 
contents squashed into it. Interestinly, when I restart the X server 
using color depth 8, everything works fine - except the dithered icons  
and the odd colors everywhere. So the mapping from color depth 8 to 24 
does not work or does not even happen. It seems easy to blame the Citrix 
client for this, however a colleague of mine is using Linux as well and 
everything works fine for him. So the problem is probably caused by the 
X server itself or by the video-device driver (NeoMagic in my case). 
Does anybody know where the mapping is supposed to happen?
