after the default install you may find that your dual displays will not function properly, only one may be displaying while the other is showing garbage color or going into sleep mode.
Well that's no good, you have 2 (or more) monitors cause it's nice to have a lot more desktop space!!! Screw this, let's get these bad boy's workin'!
you may be saying to yourself 'Uhm, I'm not really that confident with editing configuration files'.
It's cool, neither am I. I did it the easy way... or I think it's the easy way, there could be a more efficient way to do it, but hey, this worked for me, so back off!
sorry, uhm, what was I talking about???
Yeah, making more then one monitor work thus making your computer that much more bad ass!
Ok, ready? you look that monitor straight in the face and you say
"Work! Noooo! Wooork!"
Yeah, to be honest with ya' I wasn't fully expecting it to do anything, but it was worth the shot, right?
Ok, seriously, here's what I did: download the drivers for your model nvidia card (or cards) and then download the nvidia settings program.
Install both and you'll probably have to reboot the computer.
Now, assuming both installed ok, you need to run the nvidia settings program as root.
Go to your K Menu -> PBI Programs -> nvidia -> nvidia settings: right click the settings program and select 'Put into Run Dialog'
At this point you should see a 'Run Dialog' box pop up with the path to the settings program. Go to the front of that line and then type in 'kdesu ' (please note the extra space).
kdesu (if you're not sure or don't know) is KDE's equivalent to, you guessed it, *nix's su command. su, by itself, gives you root privileges but in this case it's allowing the nvidia settings program to execute with root privileges. if you execute the settings tool with out root privi's it won't be able to overwrite the xconfig file.
from here, if you've ever used nvidia's settings tools on windows, it should be fairly simple.
I run 2 monitors side by side (as im sure alot of you do, but there are other configurations) so i did this:
xserver display configuration:selected to configure my second monitor to the right of screen 0, enabled xinerama, saved it to my x configuration file and quit.
restart the computer and you should be good to go.
if you where having the same problem i was, i hope this helped.
and if not, i hope you got a little bit of a chuckle out of it.
<- obviously, latest nvidia
^ maybe not so obviously, the configuration tool.
