| **Note:** I recently got two new screens for my main display which lead to a new GPU as well, since my old nvidias didn't support the screens resolution. newer graphics cards often come with more than two outputs like my GeForce 750 with 2 DVI, 1 HDMI and 1 VGA port. I now connected the two main displays to the two DVI ports, and the old 19" display i still use as a status screen ot the VGA port. since i had some difficutlties in getting the 2-seat setup to work again on a single card i realized it is actually much simpler to just configure the card to run with two x-displays, one featuring the two main screens and the second display runs on the 19" status monitor. upon startup i start firefox with its own profile on the second display and it opens in full screen mode and shows my status display. it all looks like before, it is just a lot simpler to set up. and i must admit, i think this setup could also be possible with two separate cards installed, so you might want to try that first before following my steps below. | **Note:** If you are looking for a simple way to have an extra screen on your linux machine showing a status monitor and you don't mind the status screen to go blank when you log out or lock your workstation, skip to the end of this article and read about the new simple solution i have. If you want your status display to be shown even if you're not logged in, then the following might be the solution for you. |

| to start firefox on the second display i simply run: | |
| DISPLAY=:0.1 firefox -P Statusdisplay | |

| what's cool thoug about the 2 seat solution described below is, that you can regulate the settings (like screen saver, stand by etc.) completely autonomous for the status monitor and it even show sthe status screen when the main screen is locked.. so this might still be a better solution for some situtations.. for example when the satus display is seen by more than just the user of the main screens. | |

| i am not sure if anybody else wants to use a setup like this, but here is how i did it anyway: i used 2 24" screens, 1 old 14" screen, two nvidia graphics cards (with two ports each) and one keyboard and mouse attached to one pc. the pc is running xubuntu 12.04 64bit with the latest nvidia driver package available for xubuntu. | i am not sure if anybody else wants to use a setup like this, but here is how i did it anyway: i used 2 24" screens, 1 old 14" screen, two nvidia graphics cards (with two ports each) and one keyboard and mouse attached to one pc. the pc is running xubuntu 12.04 64bit with the latest nvidia driver package available for xubuntu. |
