You must have the ATI driver setup and working. To setup the ATI drivers on Kubuntu 7.04 Feisty read this .
After installing the proprietary ATI driver and your default monitor you can setup dual head, if your card supports it, with full 3-D. This is for the ATI Radeon X1300/X1550 Series, but you can try it with other multi-monitor cards supported by the proprietary ATI Linux driver. This should also work on laptops for the external display. You may also try setting it up in System Settings, but I haven't had luck with that.
First things first: BACK UP XORG.CONF!
open a terminal and type, which will place a copy of your xorg.conf in your home directory:
sudo cp /etc/X11/xorg.conf ~/
If thing hose, boot into safe mode in grub and at the command line type:
sudo cp /home/your_user_name/xorg.conf /etc/X11/xorg.conf
Then reboot.
Make sure your driver is working. open the terminal and type with 3-D and the ATI driver:
sudo kwrite /etc/X11/xorg.conf
(Gnome users use gedit instead of kwrite, or your favorite text
editor.)
Find Section "Device" and make sure driver is set to use
fglrx, i.e. driver "fglrx". If not change it.
Hit Ctrl+Alt+Backspace if you changed it otherwise continue.
Back in the terminal type:
fglrxinfo
You should see something similar to this:
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: Radeon X1300/X1550 Series
OpenGL version string: 2.0.6334 (8.34.8)
Next test 3-D, should run fast if everything is working, type:
fgl_glxgears
You should see something similar to this:
Using GLX_SGIX_pbuffer
3362 frames in 5.0 seconds = 672.400 FPS
3464 frames in 5.0 seconds = 692.800 FPS
3441 frames in 5.0 seconds = 688.200 FPS
Finally type this:
glxgears
If it runs fairly fast life is good.
Understanding the xorg.conf file and video.
If you do not have a Wacom tablet and remove all wacom references.
The example below is devoid of Wacom settings if you wish to use it as a
reference. Don't forget to remove it from "ServerLayout" section, should be
three lines;
InputDevice "Stylus" "SendCoreEvents"
InputDevice "Eraser" "SendCoreEvents"
InputDevice "Cursor" "SendCoreEvents"
NOTE: At anytime you can use the example xorg.conf at the bottom of the article for reference. It is a working
xorg.conf with my specific monitor removed. Be careful if you copy and paste this file!
Some editors hide charactors from webpages that will cause x to crash when it reads this
file. If you want to copy and paste use kwrite, kedit, Gedit, or even better, Vim -
stay away from kate.
IMPORTANT:
If you copy and paste my xorg.conf add your monitor and screen SETTINGS from your
xorg.conf and point to the identifiers for each, you can leave my identifiers in
place and remove those created in your xorg to make life easier, but you want your
screen size, refresh rates, and other specifics in place - the settings in the example
will crash X!
Basically setup your default monitor and copy SCREEN and MONITOR
from your xorg.conf. Save them...
Copy everything in your properly setup xorg.conf between Section "screen" and
EndSection and paste to my xorg.conf in your screen sections and do the
same for the monitor section. Leave my identifer intact and remove the one
create in your xorg.
OR
Copy your Screen, Monitor, and Device sections from your properly setup xorg.conf.
Paste them to your xorg, leaving the originals inplace and add a 2 to each sections
identifier, i.e. Identifier "my_whatever2". You now have two of each:
my_whatever
my_whatever2
Then add the second screen to Serverlayout:
screen "my_whatever" 0 0
screen "my_whatever2" RightOf "my_whatever"
Use my xorg as a reference as to what needs to be added.
I will go through this so you understand this a bit better:
MODULE section:
This is where modules get loaded, for this tutorial you should see:
Load "dri" # Maybe missing, add it.
Load "glx"
Load "GLcore"
SERVERLAYOUT section:
This is what calls all our linked sections.
screen "Default Screen" 0 0 will call "Default Screen",
which in turn loads the ati "device" section
and your monitor "monitor" section.
Think of it as a chain reaction, if I name my screen "larry"
I would call screen "larry" 0 0 in the server section.
It will go to larry in Section "Screen". In section screen if
I called my device section "moe" and my monitor "curly" larry
will execute moe and curly.
screen "Secondary Screen" RightOf "Default Screen" is simply a
repeat of your default chain reaction with different names so that
the two screens, monitors, and drivers do not clash.
What we end up with is this without all the other stuff
to cloud the view:
Section "Screen"
Identifier "larry"
Device "moe"
Monitor "curly"
Your screen settings
EndSection
Section "Device"
Identifier "moe"
Your video card/driver settings
EndSection
Section "Monitor"
Identifier "curly"
Your monitor settings
EndSection
# This is the second display.
Section "Screen"
Identifier "larry1"
Device "moe1"
Monitor "curly1"
Your screen settings
EndSection
Section "Device"
Identifier "moe1"
Your video card/driver settings
EndSection
Section "Monitor"
Identifier "curly1"
Your monitor settings
EndSection
# Execute our layout.
Section "ServerLayout"
Identifier "Default Layout"
screen "larry" 0 0
screen "larry1" RightOf "larry"
EndSection
The only other thing you need to be aware of with the ATI
driver is that "Composite" should be disabled in the Extensions
section as it is not supported.
If you are curious about the DRI it just sets permissions for any
user to access DRI. Finally Option "AIGLX" "off" The proprietary Ati driver does not
support AIGLX, which is enabled by default on (K)Ubuntu. You must
use XGL for Beryl and Compiz. You can omit this safely in most cases.
One setup you can go into System Settings under the KDE start menu and view or setup screens. Here is my xorg.conf: # /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# 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
