Hi there. I have an I810 in a box here. The box itself is one of those
"bare-bones" type systems. The audio and video are on the MB. I'm
required to load the agpgart to use XFree86. I'm loading the standard
agpgart module (with i810 support) that comes with kernel 2.4.19.

I was the guy who asked the question Ian responded to. Since then I've
gone on somewhat of a X11 freak-out rampage, trying to do all kinds of
wild and crazy things with it.

Included in my adventures was trying to control my box at work on one vc
on my home box (with the i810), while using my standard kde3.1 desktop
on another vc. It works pretty well.

Here's how I've been doing it. It is not very efficient, but it
works. The home-to-work connection is very slow because it is over
ssh, so I use blackbox. I tried using kde on the remote, but it's like
quicksand:

On the home box, I am user 'btt', and log in on the console. I have
an .xinitrc which contains:

##
xterm
##

Once logged in, I type:
btt@home$ xinit &

That starts the x11 server on :0 with a plain old xterm. Now, in the
xterm:

btt@home$ startkde

And kde starts up normally. Everything is going great. So now I switch
back to vc1 (the one initially logged in on: ctl-alt-f1) and do
another xinit, but with a twist, to start it on a separate screen:

btt@home$ xinit -- :1 &

XFree86 takes over and up comes another plain-old xterm. in the xterm:

btt@home$ ssh -X -c blowfish -l btt work.box.org
Password:
btt@work$ blackbox

.blackbox loads... (the -X is important)

Once loaded, I can switch between kde3.1 on the 'local' machine and
blackbox on the 'remote' machine by ctrl-alt-f7 and ctrl-alt-f8.

That problem has never come up here. It may be related to something
else entirely.

Good Luck!
