X31 Dual Head (Gnome, Ubuntu 7.10)

I've seen a few xorg.conf files online and I've tried some (and tinkered my own) and I can't get anything to work. If you've got working dualhead with your X31, please let me see your xorg.conf. The closest I've come to is clone view where my external monitor is running it's native res- but showing the gnome menu bars in 1024x768...it's just screwy.

I'm able at linux-- I'm not a guru by any means but...well, my "Access IBM" button is conveniently bound to start the terminal :)

Can you paste the output of xrandr -q
And which drivers are you using? radeon or fglrx?

root@bim:~# xrandr -q
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1280 x 1024
VGA-0 disconnected (normal left inverted right)
LVDS connected 1024x768+0+0 (normal left inverted right) 0mm x 0mm
1024x768 60.0*+ 60.0
800x600 60.3 59.9
640x480 59.9 59.4

(Currently not at home with other my monitor-- I'm guessing that changes entirely when I hook it up).

I'm actually using the ati driver. I've got an xorg.conf setup to use radeon driver (fglrx doesn't play nice at all with the X31). The radeon driver it bogs the whole system down. Stuff like Beryl works nice but the responsiveness of the system goes way down hill.

Alright, we'll try some xrandr fu when you hook up the 2nd monitor.

Hey I just got it.... somewhat working!!!!

It turns out having "Xinerama" in your xorg.conf causes the ATI driver to completely disable the dualhead option for X.

I took out my Xinerama line, then the AMD Catalyst Control Center works perfectly, and I can adjust my displays on the fly!

Now I just need to figure out how to get compiz to put another two gnome panels on the second monitor, and I'm set :D :D :D
