How should I configure kernel and/or Xserver ?

Tnx in advice.

eeeh the question is quite confuse there. Unless you are refering to something else, Xserver == Xorg (Xfree in old time) is intended to provide graphical user interface... why would you need to configure something about your chipset?

Are you asking how to configure X for your video card??

The thing is that this chipset has a build in video card - Intel Graphics Media Accelerator 950 and I want use it.

Additional info about chipset

herm no, it doesn't work like this. Chipset doesn't provide video, his use is to transfert data on the bus. Look at this diagram from the site you gave us : http://www.intel.com/products/i/chip...5g_diagram.gif

As you see on the left, video card is a different entity, that does use the chipset.
Anyways... use the command "lspci" to find out what chipset your video card has.
As example, on my system :
This tell me I have an nvidia chipset. You probably have an intel 950 onboard card.
You might want to try to configure your x with the command XF86config ( or xorgconfig, I don't know if Debian switched to Xorg yet).

The Intel 945G Express Chipset delivers outstanding system performance through high-bandwidth interfaces such as dual-channel DDR2 memory, 1066/800 MHz system bus, PCI Express* x16 graphics port and PCI Express x1 I/O ports, Serial ATA 3.0 Gbps and Hi-Speed USB 2.0 connectivity.

This chipset includes the Intel® GMA 950 graphics core which provides responsive graphics performance and stunning video playback.

In addition, the Intel 945G Express Chipset includes support for Intel® Active Management Technology, the next generation of remote client network management.

................................................

The new Intel® GMA 950 graphics core is an intelligent and responsive graphics engine built into the chipset that is on the motherboard. This integration provides incredible visual quality, faster graphics performance and flexible display options without the need for a separate graphics card.

So I can't understand why You still trying to tell me that there is no video card built into chipset, It seems to me that You yourself do not understand how does these things work. However my question was abot setting up xfree86 or xorg, so if You know how to help me plz write on topic.

I'm trying to install linux on a dell dimension 5100 with intel 945G chipset.

I think my kernel do not support 945G since lspci tells me that my devices are unknown. My kernel is 2.6.11-5.

Do you know wether or not kernel 2.6.12 answers that problem? I've seen some lines about it in the 2.6.12 release note.

Yes mostly new kernel helps, at list X11 starts with vesa driver and UDMA forks with intel chipset support built in. but to be honest I must say that I'm not a guru in this things.
