Hi,<BR>
<BR>
Sorry if I make you confused.<BR>
I got a graphic chip which support standard VGA registers. Debian can use it normally. I mean Xorg server. <BR>
<BR>
Now I want to compile a new Xorg server ( I didn't make any changes to the source code), but I just found that it failed.<BR>
Souce code is from Debian website. So I think that I just need ./configure && make and it should be almost same as the default one which can work with my graphic chip.<BR>
<BR>
