TwinView Kubuntu 10.4

rasperin · 06-27-10, 02:19 AM

So after an entire two days trying to get this to work on my laptop LCD it appears I cannot get this to run on both my laptop LCD and my External LCD (HDMI Connected)

Note, I can run one or the other but not both. I am trying to set this up on a Sony Vaio VPCF127FX, Kubuntu 10.4, Nvidia 330M, Drivers 195.36.24. Attached is my xorg document.

Code:

Please help

The ConnectedMonitor and CustomEDID options apply to an entire GPU, so specifying different values for the different screens on a single GPU can lead to unexpected and confusing results. To make sure things work the way you want, you should probably specify the same things for both screens:

Code:

Option    "ConnectedMonitor" "DFP-0, DFP-1"
Option    "CustomEDID" "DFP-0: /etc/X11/MS_0025.bin; DFP-1: DFP-1:/etc/X11/acer.bin"

Also, UseDisplayDevice "DFP" doesn't make a whole lot of sense when both of your connected displays are DFPs. You should specify either DFP-0 or DFP-1 (or just remove the UseDisplayDevice option entirely).

Oh and by the way, since the title of your post is "TwinView Kubuntu 10.4", I should point out that what you've configured is called "separate X screens", and is *not* TwinView. If you want TwinView, get rid of Screen1 and just set

Code:

Option    "TwinView"

on Screen0.

The thing is, for kubuntu to work on my laptop LCD, I had to define a custom EDID for that screen (a known bug with ubuntu and nvidia's 195 drivers I guess). I'm going to try the double custom EDID when I get home tonight.

I would also like to mention that nvidia-settings doesn't detect the external monitor UNLESS I disable the laptop LCD in the xorg.conf. Then it detects it as DFP-1.

I thought I'd mention that I love you! That worked, now any hints on how to get my alps touchpad working or EVGA's UV+ 19 external USB (Display Link) Display adapter to work?
