This is a lengthy question, but I award only a small amount of points for I think that the answer is (or must be) quite easy. If not, I'll raise the amount.
On my second HD, I installed the Slackware Linux distribution (Linux 2.0.0 or so) and then tried to launch XWindows.
I ran xf86config and after answering all questions correctly, tried startx.
However, I got the following error (the XF86Config file is in /home/Chris, where Chris is my login name):
No config file found!
Note, the X server no longer looks for XF86Config in $HOME.
Any ideas here how to permanently make this disappear? I am an absolute beginner at Linux, so please be patient! :-)
