Thread: Two nVidia cards won't work together...
my computer came geforce gt240, , i've been running 2 screens on (btw has vga , dvi ports i've been using, has hdmi port; can run third screen on that?), needed more room, bought geforce fx5200 (only had pci slots available) run third screen.
running 10.04, , if entered lspci see both cards, other though fx5200 didn't exist - wouldn't show in nvidia-settings.
after searching bit decided merge xorg.cong file each card 1 new xorg.conf. had install 9.10 this, if makes difference (because 10.04 refused start x when fx5200 inserted).
working single screen xorg.conf gt240, before fx5200 came along (10.04):
and xorg.conf generated "xorg -configure" , nvidia-settings when gt240 removed , fx5200 plugged in (9.10):code:section "monitor" identifier "monitor0" vendorname "unknown" modelname "acer p244w" horizsync 31.0 - 83.0 vertrefresh 56.0 - 76.0 option "dpms" # horizsync source: edid, vertrefresh source: edid endsection section "screen" identifier "screen0" device "device0" monitor "monitor0" option "twinview" "1" option "twinviewxineramainfoorder" "crt-1" option "metamodes" "crt: nvidia-auto-select +0+0, dfp: nvidia-auto-select +1920+0" option "sli" "auto" option "addargbglxvisuals" "true" defaultdepth 24 subsection "display" depth 24 endsubsection endsection section "module" load "glx" endsection section "inputdevice" identifier "mouse0" driver "mouse" option "protocol" "auto" option "device" "/dev/psaux" option "emulate3buttons" "no" option "zaxismapping" "4 5" endsection section "inputdevice" identifier "keyboard0" driver "kbd" # generated default endsection section "serverlayout" identifier "layout0" screen 0 "screen0" 0 0 inputdevice "keyboard0" "corekeyboard" inputdevice "mouse0" "corepointer" option "xinerama" "0" endsection section "device" identifier "device0" vendorname "nvidia corporation" boardname "geforce gt 240" driver "nvidia" option "nologo" "true" endsection
-- btw geforce 6150 integrated graphics gets disabled gt240 not fx5200. there no screen plugged it, despite says.

have got xorg.conf right?
problem drivers? hardware drivers seems have room single video driver?
recommends 173 fx5200, , 185 gt240, can choose 1 or other, , in xorg.conf both cards list driver "nvidia", i'm wondering if drivers these 2 cards incompatible, , need somehow install , use 2 separate drivers?
back in bizarro world here, 10.04 load x fx5200 - not sure did make happen.
anyway, 99.9% sure problem drivers, , need separate driver each card - if trying gt240 old ver. 173 driver, ubuntu explicitly says card won't work driver. , if have fx5200 working 173 driver , upgrade latest driver , restart ubuntu goes it's low-res mode (through gt240!).
i'm convinced (perhaps others reading knew) drivers incompatible, how go installing 2 different nvidia drivers alongside each other, , 2 cards use respective drivers?
marking solved, don't think it's accurate representation of problem anymore, more here: http://ubuntuforums.org/showthread.php?p=9817070
