Hi! Why do you like to use X11-v3 whith xlib6-v4? I wouln´t do that! Are you shure you like to use X11-v4? Now it is a part of the unstable Woody. If you like a stable Debian, use potato! To create the XF86Config file you can install the package xviewdetect and run the command: anXious And why you can´t use XF86Setup? I mean this simple tool shoud work with X11-v4 too. Cu, Timo
