First off, please excuse my bad english, i´m german.

I run Slackware 9.1 ( now updated to 'current' ) on my old IBM Thinkpad 600E.
When I first installed the system on the laptop ( i´m running Slack on two other machines too with no X-related problems... ), i had major problems getting X to work because I don´t know the right settings for the laptops display.
The biggest problem was the screen getting extremly dark everytime i switched to a shell (ctrl-alt-F2 of F3 or F4........ ) and then switched back to X ( ctrl-alt-F7 )


This is what I did to solve the problem ( after hours of 'try and error' ):
I knew I do not have the problem with Knoppix 3.4. I have tryed this before and I knew when i boot Knoppix, it will give me a 100% working XF86Config-4 file.
So I first installed Slackware ( 9.1 ) on the old Laptop as usual.
Then i booted the laptop with Knoppix 3.4 and switched over to a shell.
I copyed the working XF86Config-4 to some place on the hd.
After doing this, I left Knoppix and booted Slackware.
I renamed the original XF86Config ( /etc/X11/XF86Config ) to XF86Config.original
Then I copyed the Knoppix XF86Config-4 to /etc/X11 and renamed it to XF86Config ( as far as i know you do not need to rename it because X will lookup for XF86Config-4 anyway, but i did and it works fine )
That´s all. Start X and be happy....
( even the mousewheel is working fine )


Upgrading ?
Later then I updated to Slackware -current, what replaces Xfree86 with Xorg.
The configurationfile for xorg is xorg.conf ( also located in /etc/X11 )
I renamed xorg.conf to xorg.conf.original and then i renamed my XF86Config ( it´s still there after upgrading ) to xorg.conf
That´s it


Hope this can help a little bit.
Knoppix is always a good help when you are looking for the right settings in your configfiles

Good way to get it working. Why do all the work if knoppix can do it?

And your english isn't bad at all, it is easier to understand than some of my american friends
