Dualhead on ATI Proprietary Drivers

[Bana]

I am trying to get ATI's proprietary drivers (3.12.0) working in a dual head configuration with my Radeon 9700 Pro. I am trying to use fglrxconfig to make the necessary XF86Config-4 file (ponted to by a soft link from xorg.conf).

The problem is: the secondary display shows only a garbled display as if it was cloning the primary display all except for the mouse (which properly scrolls over to that screen and moves around (the cursor itself is just a block)). Windows; however, cannot be moved to the second display. It is almost like it is out of scan range but I have tried switching the monitors (primary and secondary) and the problem is reversed, so I don't think it is the monitor refresh settings. I will attach my xorg.conf

BANA,

this part in particular:

Screen 0 "Screen0" RightOf "Screen1"
Screen 1 "Screen1" 0 0
InputDevice "Mouse0" "CorePointer"

Option "Xinerama" "on"

EndSection

imdeemvp: Unfortunately that config is for the normal config of a dual head (using non-proprietary drivers) I guess that is what I am going to try next though (I can always just stick in another xorg.conf whenever I need to use accelerated OGL I guess).

Using non-proprietary radeon driver I was able to get Dualhead working with this config: http://www.fedoraforum.org/forum/sho...94&postcount=4

Hey Bana,

I'm glad I was of some help. I'm in the same boat as you regarding the proprietary driver from ATI. I can't get dual head working using their driver either. I too had to resign myself to having 2 xorg.conf files. One for work that uses dual-head and the non-3D drivers (the config you saw) and another for "recreational" use that foregoes the second monitor but gives me 3D acceleration by using ATI's 'fglrx' driver.

I upgraded to 3.12, but I still have the same problem. I left feedback on ATI's Linux driver page but since the Linux drivers are low priority and our Mobility cards are not supported, I'm certainly not holding my breath...

hey guys will this work with a laptop as welll?............i know dumb question :o

[Bana]

imdeemvp: that is what olivierv has (he was referring to the Mobile chipset which is ATI's line of graphical chips).

olivierv: yes thank you for posting your config, I am glad but sad that we are both in the same predicament as it tells me that it is not me doing something wrong I can't wait for ATI to step up their linux drivers, until then I am leaning towards Nvidia towards my next purchase (those new Geforce 6800GTs look mighty fine )
