I have an ATI RAdeon 9600 graphics card, with dual heads.

Both of my screens are clones, and I am trying to get an "extended desktop"

I tried making changes to the Xfree86 config file (at the instruction of a "how to" tutorial), but I noticed no change - the displays are still cloned.

here is my configuration file :



# XFree86 4 configuration created by pyxf86config

Section "ServerLayout"
Identifier "dual layout"
Screen "Screen0"
Screen "Screen1" rightof "screen0"
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"
# RgbPath is the location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.

# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

RgbPath "/usr/X11R6/lib/X11/rgb"
FontPath "unix/:7100"

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"

# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"

any sugguestions?

Thanks,

hello
did you ever manage to get this problem sorted?
as it is the exact problem i was having for the past year or so....and could never sort it.
I managed to get dual display...but it was like a wierd clone/dual setup...each screen would show the same thing however you could mouse between the screens

So i gave up and went back to winblows

Kane

No, I never solved it. I had the same thing going, where there were two screens, and I could move the mouse from one to the other, but both had a "start menu" and windows couldn't move from one to the other....

I went back to Windoze, and now I am running 4 monitors.

its a shame really...it was the only thing stopping me from moving permanently to linux

Kane

i know that after you have the latest ATi drivers installed, it'll add an ATi configuration program. I have SuSe 9.1, and it added it under the System menu, I believe. There's a tab to assist in setting up dual monitors... I hope this helps!
