Re: Local Multi-User X (?) problems

Yihaaaa! It works! disabling DRI and using the -prefbusid option did the 
trick! Thanks a lot!

But then, since there are a few issues it would be good to understand, 
let's take it anyway...:

Nope!

Yes. 8 times... :-)

Hereby attached!

Yes. I think I once read that if you build a kernel for a specific 
system, and there is something you use all the time, compile it into 
the kernel, if you use it just occasionally, compile it as a module.

OK...

Yup:
 kjetil@owl:/dev/input> ls
event0  event1  event2  event3  mice  mouse0  mouse1

Dunno.

Yup... 

BTW, here's one point you might want to add something like this in a 
Troubleshooting section of your HOWTO:

Q: e2fsck complains I have a bad superblock after I enabled devfs. In 
fact, it appears all the superblocks are bad, and I'm scared. What do I 
do?

A: Make sure devfsd is running.

:-) This put me off for several days...

I have automatic mounting enabled in the kernel.

Yup, as I said, it works! :-)

Yup. Since it works now, I'll stick to kdm.

I see!

OK.

I guess I might as well ask right now: I was thinking about buying a 
gadget where I can get two PS/2 ports from a USB-port, like this:
http://www.clasohlson.no/images/products/N/hi/A/324024_Xw4.jpg
I have no further specs on it, but do you guys think it would "work"? 
The idea is to use one of those for the second keyboard and mouse.

Best,
