Hey

Hardware:
HP Pavilion a6412.sc
Intel Pentium Dual Core 1.8
Gráfic Card: Asus EAX 550HM512
Grafic processor: ATI Radeon X550
Mail Monitor: DVI 22 " flat
Second Monitor: VGA 19" (the big ones, crt I belive)
Software: Ubuntu 8.04

My problem is that I want to have different picture in my two screens. I have the ATI driver installed and working, I have grafics asceleration. I´ve tried to extend the desktop (BigDesktop option in Catalyst) but din´t work.I only get Cloned images. I have extended desktop only in login screen, then goes back to cloned. I am trying to configure DualHead but doesn´t go either. this is what I did:

sudo aticonfig --initial=dual-head --screen-layout=above

Then I get this:

Found fglrx primary device section
Found fglrx secondary device section
screen layout section corrupted.

I really apreciate any help or information that will help me to set two different Images in my monitors.

Here I paste my Xorg

new to this but have been playing aroudn with dual heads

i think you might be confusing methods...

the problem maybe that u have enabled bigdesktop before running:


sudo aticonfig --initial=dual-head --screen-layout=above

without bigdesktop enabled will create two desktops that u cannot drag and drop application between with there own seperate toolbars

my xorg with out bigdesktop enabled looked like



Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "aticonfig-Screen[0]" 0 0
Screen "aticonfig-Screen[1]" RightOf "aticonfig-Screen[0]"
EndSection

Section "Files"
EndSection

Section "Module"
EndSection

Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "gb"
EndSection

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
EndSection
Section "Monitor"
Identifier "aticonfig-Monitor[0]"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection

Section "Monitor"
Identifier "aticonfig-Monitor[1]"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection

Section "Device"
Identifier "aticonfig-Device[0]"
Driver "fglrx"
BusID "PCI:5:0:0"
EndSection

Section "Device"
Identifier "aticonfig-Device[1]"
Driver "fglrx"
BusID "PCI:5:0:0"
Screen 1
EndSection

Section "Screen"
Identifier "aticonfig-Screen[0]"
Device "aticonfig-Device[0]"
Monitor "aticonfig-Monitor[0]"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection

Section "Screen"
Identifier "aticonfig-Screen[1]"
Device "aticonfig-Device[1]"
Monitor "aticonfig-Monitor[1]"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection



but i assume the two seperate desktops is not wat u want if u wanted to use bigdesktop try ziox guid:

note
The use of sudo aticonfig --initial=dual-head --screen-layout=above would set u up nicely for use of Xienrama method by simply adding to the top of ur xorg.conf:



Section "ServerFlags"
Option "Xinerama" "ON"
EndSection


all dual head methods are in another ziox post here:

hope this answered your question (sorry if it didn't)

Hi
First, Thanks for replying.
What I really need is to have two differents pictures in each monitor. It really doesn´t matter if I cannot drag applications between monitors, as long as the picture is different and of course, I have access to both desktops/monitors whenever I want.

I´ve tried configuring the second device manualy on the Xorg, but failed...

How did you made it??

Thanks

you could try creating a clean xorg file


sudo dpkg-reconfgiure xserver-xorg

there is some options to run through note this will reset input devices as well.

then run:


sudo aticonfig --initial=dual-head --screen-layout=above

note - might have to:
i think when i did it there was an issue that there was no driver option so i added

Driver ""
in the device section in my xorg.conf using

gksudo gedit /etc/X11/xorg.conf

then re run aticonfig line

hope this helps
