I guess RandR 1.2 would be the correct way of doing multi-head support these days. Support for it has been promised "in a future release" a year ago, but I'm not holding my breath.
If you need compositing, but must use xinerama, you can always use Xgl.

This isn't an option in Intrepid anymore .

Is there another way to go about this? I have a 37" HDTV and a 19" Dell widescreen, the Dell I would like to rotate 90 degrees to make it easier to read text files etc.

Thanks.

Hi there,

Still no news for this feature ? I just updated my kubuntu with nvidia 177 and had a kind of hope that it could help me but no ...

Regards,

I've got one screen rotated. This is my xorg.conf
Maybe it helps you.

Default Re: Rotation of only one screen (with TwinView)

Thanks, assem046

My /etc/x11/xorg.conf (generated by nvidia-settings) looks like

Code:
Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Iiyama PLE2403WS"
    HorizSync       30.0 - 83.0
    VertRefresh     56.0 - 76.0
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce 9800 GTX/9800 GTX+"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "1"
    Option         "metamodes" "DFP-0: nvidia-auto-select +0+0, DFP-1: nvidia-auto-select +1920+0"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection
I guess something should be changed in the "metamodes" option in ordre to rotate one monitor but don't know what... if exists.

Default Re: Rotation of only one screen (with TwinView)

@assem046, @phw: Do either of those configurations allow a single monitor to be rotated with acceleration on both screens?

The nvidia Linux driver notes say that with TwinView rotation can only be done across all screens. nVidia on OS X supports single-screen rotation with acceleration on all screens, this should be possible to support in Linux. Is this feature planned in a future release?

Default Re: Rotation of only one screen (with TwinView)

^ I'm curious as well. I just purchased a Dell monitor (now have two) that rotates (pivot) from landscape to portrait mode and I would like to know if he/she really has found a way using Twinview to get one of the two screens to rotate so it is in portrait mode. All the research I have done so far has pointed to "no" so far, but I'm optimistic that Linux users can still have this feature (at some point in the near future) without losing Compiz or switching to the XGL server.

Default Re: Rotation of only one screen (with TwinView)

Did you try these options from my xorg.conf, see below?

Section "ServerLayout"
Identifier "Layout[all]"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" RightOf "Screen0"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
Option "Clone" "off"
Option "Xinerama" "off"
EndSection

# Monitor you want to rotate
Section "Monitor"
# Add here your own values.

Option "RandRRotation" "True"
Option "Rotate" "Inverted"
# Valid values for rotation are "normal", "left", "right", and "inverted".
EndSection

#Look for both screen sections:
Section "Screen"
Option "TwinViewXineramaInfoOrder" "CRT-0"
Option "TwinView" "0"
Option "metamodes" "DFP: 1680x1050_60 +0+0"
EndSection

Let us know if it works for you.
Always check the logs for errors or warnings!

Default Re: Rotation of only one screen (with TwinView)

Thanks for posting your xorg file. I tried it out, and indeed I did get one screen rotated with 3d acceleration. Unfortunately though, it doesn't create a single workspace that allows me to drag windows between the screens. Seems like i'll never be able to get this set up... Nvidia really dropped the ball on this one. I hear ATI supports randr now. I guess my next graphics card will be from them.

Default Re: Rotation of only one screen (with TwinView)

(same as 09-06-07, 02:59 PM )

Up !!

Is there a way to allow this rotation of only one screen in twinview mode ?

I just check from time to time.. It s a pity to have such a nice graphic card and dual monitors and not be able to do this !

Thanks!

Nvidia: Are you listening to us at all? People have been asking for this for years now. You promised randr support three years ago and still no progress. It doesn't matter if it is through randr or not, but please do add the ability to rotate a screen in a dual screen setup. This is really frustrating for us.
