KDE desktop won't load in X window

[manza7]

Hi

 

I have been struggling with this problem for a while, hope some of you out

there can help, basically, I would like to access a linux file server using

VNC client and run KDE desktop, currently, I can connect if I use GNOME

desktop, if I use KDE, it just give me a blank screen.

 

The following is my network configuration:

 

Server: Compaq AP550 (as Linux file Server in a network closet, no keyboard,

no mouse attached)

OS on server : Mandrake 9.1

XFree86 : 4.3.0

Network : 100M Ethernet

Clients : W2K connect to Compaq AP550 linux server using VNC client (GNOME

desktop runs fine)

 

Problem : If I attach a mouse and keyboard to the linux server, select KDE as

desktop and login, KDE runs perfectly, however, when I try accessing the

server using VNC client, GNOME desktop runs but KDE desktop will not come

up, it gives me a blank screen but logs the following in .xsession-errors:

I read many articles concerning issues with NVIDIA graphics card so I

included part of XF86Config-4 files for your review, I even recently tried commenting out the LOAD "GLX" line but the problem persists.

If I VNC to the server using GNOME desktop, open a terminal window andtype

"startkde", I get pretty well the same error messages.

 

Questions:

 

. How do I fix that? I would like to use KDE since I prefer it better than

GNOME

. Which file is being used XF86Config or XF86Config-4, do I need both?

. If I make changes to XF86Config or XF86Config-4, do I have to reboot for

it to take effect?

 

This really puzzled me, any help is appreciated.

 

Thanks
