Nvidia Dual Head / Dual monitor Fix
BugFix:
Dual-Head monitor problems:- seen in versions 7.04 (& beta) / 7.10
To fix this is much easier than it at first appears, first a warning!
Do not try to use the tool under "System | Administration | Screens & Graphics"
-------------------------------------------------------------------------------
When I tried this the system lost the previous {working} settings and
althought it attempted to boot nothing appeared on the screen, trying
CTRL+ALT+F2 did not bring up even a text mode login (i.e. no login) and
NO display(s) showing at all!
Instead use the following method which works perfectly...
Fix:
Once you have installed and downloaded ALL the latest updates for
version 7.10, and you have activated / installed the "Restricted mode Driver"
for "Nvidia", let the OS and computer finish fully updating. Once the drive
stops running and or the processes have finished. You must install the
'restricted' mode driver or this will not work.
Remember to wait until this has all happened, (use the System |
Administration | System monitor, will help, when your CPU[s] have
finished major work) then reboot when prompted.
Now after the reboot and the clean Login, wait three minutes
(use screensaver to time this) and then use the following (I will try to
replicate the prompts etc. that you will/may receive.
Go to "Applications | Accessories | Terminal"
You'll get a prompt like the following:
response [EMAIL PROTECTED]:~$ Now type after
the prompt
[EMAIL PROTECTED]:~$ sudo su [Enter] {Forces user
into super-user mode}
response [sudo] password for User: Enter your
password
response [EMAIL PROTECTED]:/home/User Now type the
following command
[EMAIL PROTECTED]:/home/User# nvidia-settings [Enter]
response
--------> A new window will appear with the Nvidia Corporation Logo in
it.
The nvidia 'control panel' will now appear and here you
can set your various settings for dual head support.
Here you can set things up, using the {I recommend
using Dual-Monitor support, which allows different stuff on each
monitor.}
Select the tag - "X Server Display Configuration"
If one of the settings you need to adjust is not listed try
switching into 'Advanced... ', if you don't understand this, stay in 'Normal...
'
If you want to play with the fun compiz fusion display tool
(makes Vista display stuff look like a school-kid <g>, see below) then remember
to also turn on the "Enable Xinerama" tick box.
When you've fully finished remember to click "Save to X
Configuration File" and "OK".
If you don't do this your new settings will NOT be written to the
"xconf.cfg" file. I advise you, unless you have many years experience
with Linux and UNIX, just don't try to directly edit this file as most
new users don't understand how much detail 'X' requires, stay with using
the Nvidia tool above.
"exit" {at the prompt - leaves sudo su mode} and "exit" the
terminal... ( - which clears and closes the terminal.) if things don't
clean up properly (happened to me once) then from the X desktop if you
can't "exit" kill {click [X]} the terminal window (which will close both
nvidia settings window and terminal.)
or when instructed by the Nvidia control panel, go to ---> Reboot.
-----
Thats it now all you have to do is ---> and reload your OS, and
login... Now just for fun a tip...
Go to "System | Administration | Synaptic Package Manager",
after logging back in, and once it finishes downloading the new
application lists, "Search" for 'compiz' and download the "Advanced
Desktop Effects Settings" tool, let it install {it should now be
installed near the top of your "System | Preferences " list,} have fun
playing with this.
You may have to re-adjust the frequency for some monitors to get
the best settings, after rebooting.
You shouldn't need another reboot, remember that the WRONG FREQUENCY
COULD DAMAGE YOUR HARDWARE! so be careful to have the manufacturers full
specifications for the monitor[s] you are using. Most monitors have the
manufacturers information about model number etc. On the rear on some
kind of label, if it is not stamped into the plastic moulding.
Whalla... All should now be O.K. Enjoy

N.B. A note to ATI users, you should most likely need to find out the
name of the programme that runs the settings for your setup. (Instead of
'nvidia-settings'.)
You may have to go to the ATI web site to find this information, but
it's probably something very similar.
