dual monitor support in Madriva 10.1

[kapleau 0]

i'm trying to get dual monitor support working in Mandriva 10.1 and having no luck. i have a dual head Matrox Millenium G550 AGP video card.

 

when i install the OS i get 3 choices: configure heads independantly, start with Xinerama extensions and configure only Matrox G550. if i choose either of the 1st 2 options the right monitor shows the right hand side of the screen (only the trash bin is visible on the desktop) but there is no output on the left monitor. if i choose the 3rd option i get video from both monitors but they are mirrored (i.e. - the full desktop on each monitor and any action you do on one desktop is mirrored on the other).

 

the same card worked fine under Mandrake 8.2 and i didn't have to configure anything.

 

the driver section for the video card in XF86Config looks like this:

 

Driver "mga"

Video ram 32768

Bus ID "PCI:1:0:0"

Options "DPMS"

 

i have read about setting up the XF86Config "Scrren 1" and "Screen 2" settings as well as the relationship between Screen 1 and Screen2 (i.e.-Scren 2 right of Screen 1) but i didn't find these sections in XF86Config.

 

Any help would be greatly appreciated. Thanks

hmmm let me think... I know I did this with an nvidia card - I had to add a twinview option...

 

Perhaps something like this - thanks to google.

 

Section "ServerFlags"

Option "Xinerama" "on"

EndSection

Section "Device"

Identifier "Matrox0"

Driver "mga"

BusID "PCI:1:0:0" #check this with lspci

Screen 0

EndSection

Section "Device"

Identifier "Matrox1"

Driver "mga"

BusID "PCI:1:0:0" #check this with lspci

Screen 1

EndSection
