Hey guys!

As finals come to a close i thought i'd attempt to make my triple monitor set up work with compositing again.

I have 3 monitors, the left 2 are driven by my nvidia gtx 570 and the rightmost one is driven by my intel sandy bridge i5.

I feel like I'm getting close to making it work but I just need some advice on what to try next

Here is my xorg.conf

Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" LeftOf "Screen0" Screen 2 "Screen2" RightOf "Screen0" Option "Xinerama" "1" EndSection Section "Monitor" Identifier "DFP-0" EndSection Section "Monitor" Identifier "DFP-2" EndSection Section "Monitor" Identifier "HDMI1" Option "Rotate" "Left" EndSection Section "Device" Identifier "Device0" Driver "nvidia" BusID "PCI:1:0:0" #Option "MetaModes" "DFP-0: nvidia-auto-select +1024+0, DFP-2: nvidia-auto-select { Rotation=left }" Screen 0 EndSection Section "Device" Identifier "Device1" Driver "nvidia" BusID "PCI:1:0:0" Option "MetaModes" "DFP-2: nvidia-auto-select { Rotation=left }" Screen 1 EndSection Section "Device" Identifier "Device2" Driver "intel" BusID "PCI:0:2:0" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "DFP-0" EndSection Section "Screen" Identifier "Screen1" Device "Device1" Monitor "DFP-2" EndSection Section "Screen" Identifier "Screen2" Device "Device2" Monitor "HDMI1" EndSection Section "Extensions" Option "Composite" "disable" EndSection

When I enable compositing, All three monitors are still displaying things, but all three monitors start from the left side of the 3 displays

Here is an image of what's happening

Any suggestions on how to improve this would appreciated

Thanks!

*Edit*

Forgot to mention that this is what happens if I merge the two left monitors into one nvidia device

*Edit 2*

Also forgot to mention that the same thing happens when I'm using the nouveau driver.

*Edit 3*

After fiddling with it some more it became apparent that all 3 screens are being composited, When I set the intel display as the left most monitor it was being composited ok but the other two screens were showing duplicates of the intel screen. It seems that the compositor is taking in all 3 screens at once and then displaying them back starting from the top left on each monitor (does this make sense). So what it seems needs to happen is that I need to shift what is being displayed on each monitor, however the input is already correct (if I click on the left side of the second screen it will show a click on the right half kinda thing). Does anyone have any ideas?
