[SOLVED!] Finally!! 3 working monitors under Ubuntu - Mark - 13-11-2010

[SOLVED!] Finally!! 3 working monitors under Ubuntu

It's been a long ride, but finally i've got to the end. After messing with my previous 10.04 installation until it would no longer boot, then to installing 10.10 to find out that it wouldn't recognise multiple graphics cards. Attempting to re-install 10.04 was no walk in the park.. I burnt the disk, wouldn't boot, tried unetbooting, wouldn't boot, burnt 4 disks, wouldn't boot, (This is also after downloading different ISO files), new DVD drive. WALLAH! And here i am, in a clean install of Ubuntu 10.04, 32 bit, desktop edition.

And here's how i did it

Steps

1) System > Administration > Hardware Drivers
(NVIDIA accelerated graphics driver (version current) [Recommended] - Activate.

2) Reboot

3) On reboot, only my main monitor was active, so i enabled my second (on the same card) as another seperate x screen. Resolution keep on auto for all monitors.

4) Reboot - After i rebooted this time my second graphics card and third monitor wasn't even recognised never mind showing, but i went ahead and:

5) Enabled Xinerama

6) Reboot

7) Enabled my third monitor as a seperate x screen. (Now re-recognised with Xinerama enabled)

8) Reboot

9) Re-positioned the monitors in the configuration, dragged / moved to represent the actual positioning on my desk.

10) Reboot

11) :yay :yay

All of these steps were perfomed using the "NVIDIA X Server Settings" under System > Administration.

Configuration as it is now:

There you go Mark, I figured you would get it eventually. There is no better teacher than failure.

That's me. The thought of giving up never enters my mind. :ninja
