Thread: 3 identical monitors, 2 video cards (onboard intel, external ati)

dear all,

after searching many hours hope find solution here.
use ubuntu 10.04 (64 bit) 2 video cards

code:

$ lspci | grep vga  00:02.0 vga compatible controller: intel corporation 82437fx (rev 09)  01:00.0 vga compatible controller: ati technologies inc rv516 [radeon x1300/x1550 series]

i have connected 3 monitors, samsung syncmaster 2443. have no xorg.conf , 2 monitors (attached on-board intel card) have same strange output while other remains black, also

code:

$ xrandr -q  xrandr: failed size of gamma output default  screen 0: minimum 640 x 480, current 1600 x 1200, maximum 1600 x 1200  default connected 1600x1200+0+0 0mm x 0mm     1600x1200       0.0*      1280x1024       0.0       1024x768        0.0       800x600         0.0       640x480         0.0

i have no clue how use 3 monitors 2 cards. using of cards when disabling other works smoothly. doing wrong? miss setting? need (manually) write xorg.conf? appreciated!

many in advance!

regards,
erik

ok, found 1 error, added ppa: xorg-edgers/ppa (and had added ppa:glasen/intel-driver well). removing first gave me 2 monitors worked again.

xrandr results in:

i have tried generating xorg.conf file switching console mode (ctrl-alt-f1) , typing

code:

sudo service gdm stop  sudo xorg -configure  sudo x -config ~/xorg.conf.custom

however, leaves me 3 blanks screens. shouldn't @ least give me 2 working monitors?

tried following xorg.conf without success:

code:
