Linux Dual Monitor under Ubuntu Dapper (Ati)

relix · 17 Mar 2006

So I finally got to install the frglx drivers for my Ati card. Now I want to use my two monitors for "Big Desktop" (1 desktop spanned over two monitors), but I just can't get it to work right. Either it just clones, or it starts up two differint X servers for each screen.

Anyone know how to do it? Also, I've heard a great many saying "run fglxconfig for complicated setups", but somehow that didn't get on my system. It's just a "command not found".

Here's my xorg.conf (I've tried many things and made many changes already, but this is the current one)

Code:

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

I have no idea how to do this, but if you find out, please post here, I've got an ATI based PC with 2 19" flat panels at work, and I'm hoping to switch to Ubuntu when dapper gets released.

(I'll poke around the net and see if I can find something and post it here too)

[Jonny] · 7 Apr 2006

Perhaps the ubuntu forums would be a better place for this?

glaeken · 7 Apr 2006

Seconded, the Ubuntu forums are filled with very knowledgable people. Whish I could help, but I've never had to deal with an ATI dual monitor setup, only nvidia and it was pretty simple.

relix · 7 Apr 2006

Yeah, the ubuntu forums didn't help. But looks like I found the problem, it's Dapper. Somehow, now that I've switched to Breezy, and just used the aticonfig --dtop=horizontal option, it works flawlessy. Just like Windows with Ultramon.

Pygo · 5 May 2006

Think I have any luck with doing that on slackware (I'll try ubuntu someday) using two nVidia cards and three monitors?

EDIT - sorry to dig up an old thread.

Its easy with nVidia's

it work with ATI too (i use dri but it should work with fxgl too)
you need to start x with dual layout

Code:

startx -- -layout Dual

and in my xorg.conf it is like that:

i had few problem on my laptop with that (only one screen was loading) but it worked after few try

punterfpc · 8 Jun 2006

I have dual monitors up and running in DAPPER DRAKE... I have a Radeon 9600XT AIW.

The easiest way to get this to work is to install Easy Ubuntu and all the goodies it comes with (including the ATI flgrx drivers and aticonfig...). If you already have the drivers and need aticonfig, you can get it using Synaptic.

In the terminal do the following (as mentioned above...):

aticonfig --initial=dual-head --screen-layout=right
aticonfig --dtop=horizontal --overlay-on=1

Now, restart the computer (yes, you actually have to RESTART the whole computer not just X). When you log back into gnome, change your resolution to the same height but twice the width by going to

System > Preferences > Screen Resolution

So, for instance, since I am using two 17" CRTs both at 1280x1024, you would make the resolution 2560x1024. That's all there is to it. In terms of 3D acceleration, it beats me... I guess you can't have the best of both worlds yet... or maybe you can, we'll see if anyone has any ideas. In the meantime, I hope my post helped someone out.

tronica · 10 Jun 2006

first make sure you have the ati driver installed and setup correctly. Making sure you change the driver part in the xorg.conf to fglrx. Then run this:

aticonfig --initial=dual-head
Click to expand...

then edit your xorg.conf and add this to your serverlayout section:

Option "Xinerama" "on"
Option "Clone" "off"

and that should get you going. At least thats how i did it and had no probs.
