Haven’t used Linux in a long time (since 2008) I have forgotten a lot of stuff and so many thing have changed I feel a bit lost. I’m trying to set up my nvidia 550ti with the binary nvidia driver and my intergrated intel graphics on my i5 2500k to work nicely together. The only thing I need is all three monitors going, one desktop, three monitors.
When I first installed ubuntu it appeared to have worked with the built in open source drivers but I was getting weird lock ups and graphical glitches. Reading up on the newest nvidia driver (319.32) it now supports RandR 1.4, XRandR, better UEFI support, and new GPU support. Since I’m runing a UEFI system, and I plan on getting a 760 soon, I figured install the driver and see if that fixes anything. Well it worked perfectly, the system is stable and all of my glitches are gone, but the third display pluged into my motherboard still doesnt seem to work. Whats weird is that the display is not on standby, the power led is on and it seems to be receiving a signal.
Heres what I’ve tried so far
Changing the primary graphics in my bios to integrated (that shut off my first two displays all together)
Setting the primary graphics to Auto (that changed nothing)
I know that to use three displays off of a Fermi card I need two identical cards in SLI, thats why I’m trying to use my 550ti and the built in intel graphics
Here is the current output for
sudo lspci | grep VGA

Here is the output for
sudo lshw -C video

So it seems to me that my Intel graphics are detected, for some reason I can’t see the third display in System Settings> Displays
I will upload my current Xorg config and hope that someone can help me set up all three displays with xinerama or some alternative
Here is the Xorg config the NVIDIA settings tool gave me (I have yet to replace the modified one with my original, I don’t want to break anything)
