Dual Monitors on one Card (nvidia)
 

SuSE 8.2
2.4.20-64GB-SMP

I have a GeForce 4MX that has dual head output but XFREE86 and SaX2 won't let me use both of them. I used to run dual monitors with seperate cards a few years ago with no problems. I installed the latest nvidia driver from nvidia.com but still it says I don't have a dual head option. During bootup, borth monitors are active (mirror displays), so I know they work.



Any suggestions? This card has dual VGA outputs. THe monitors are HANSOL 920As. 19".

this is an issue lots of people have, first off I am an nvidia user and have been sence I started 5 years ago, I have run dual display across 1 card, and quad display across 3 cards. my first word of advice, ditch the suse utils, no util will be able to configure this for you. now go to www.nvidia.com and d-load the latest driver for linux, should be a .run file, after it is d-loaded enter root mode (su - then password) type chmod 770 (filename).run
now type ./(filename).run it should go through a few things, use defaults etc.
after that is done you will need to have an /etc/X11/XF86Config file that is configured properly, suse probably has a proprietary one, so I will paste one in here with general defaults and comments from me

I am having trouble pasting the file, will try again in new reply

Thanks for the tips. I used some portions of your file along with the one my system started with. After a bit of trial and error, everythign is looking good.

Thanks again.

I now know more about X.

glad I could help, i have built my x config file over 4 years, I gave you samples from it, the real thing was beyong the character count
