Help: radeon X300 dual-head configuration

[Guest cvguy]

Hi.

 

I am trying to configure Radeon X300 to use dual-head mode. I have two identical Dell 2001fp monitors with DVI inputs. My Radeon X300 came with two DVI outputs, so I connected each of them to the two 2001fp. I use Xorg 6.8.2 and 2.6.8.1-12mdk kernel. Following is my xorg.conf file

 

==============================================================================

Section "Files"

# Multiple FontPath entries are allowed (they are concatenated together)

# By default, Mandrake 6.0 and later now use a font server independent of

# the X server to render fonts.

FontPath "unix/:-1"

#FontPath "/usr/lib/X11/fonts/misc/" # for hangul fonts

EndSection

 

Section "ServerFlags"

#DontZap # disable <Crtl><Alt><BS> (server abort)

AllowMouseOpenFail # allows the server to start up even if the mouse doesn't work

#DontZoom # disable <Crtl><Alt><KP_+>/<KP_-> (resolution switching)

I tried this configuration but the dual head does not work. It only shows one screen and the other one is blank. If I enable Xinerama option, then it shows exact replica of one screen to the other, but I cannot use the two screen independently.

 

Can anyone help please?

 

Thank you.

Im bringing this to the top because I have the exact same problem, with the exact same card, only difference is I'm using different monitors from the op.

Have a look at this link: https://lg3d-core.dev.java.net/etc/XF86Config-4.talin-single

 

it lists a config. The lines I think you'll be interested in are:

 

Option "DesktopSetup" "0x00000000" # Single -or- Dual Head

 

then check the ServerLayout section at the bottom, to choose one of the Dual Head modes.

 

I've not got this card, so can't check and test to see if it works or not, but hope it helps!!
