Thread: Second monitor help

i installed lubuntu on dell dimension 8300, have 2 dell lcd monitors, booted livecd , both monitors worked after installation onle 1 of them works. if go nvidia x server settings shows 1 monitor, i've had ubuntu before dual screen setup (extended desktop). appreciated.

hi,

have same problem computer. have not been able solve it. have post more information community including /etc/x11/xorg.conf

in case /etc/x11/xorg.conf seems have been replaced following rather simple one:

section "screen"
identifier "default screen"
option "addargbglxvisuals" "true"
endsection

section "device"
identifier "default device"
option "nologo" "true"
endsection


don't know how revise this. have done third party driver download thing , nvivia x server settings program not seem know how reconfigure xorg.conf file. , not know how or how manually. have tried , made mess , ended reinstalling ubuntu.

strange thing system recognizes the 2 monitors when start , shut down.

suggest posting results of lspci command. mine gives following results.
