Second Monitor left of internal monitor turns internal monitor black

Second Monitor left of internal monitor turns internal monitor black

Hi there,

a few days ago I installed Ubuntu Gnome 14.04 on my Thinkpad W530. It has the
following specifications:

Intel Core i7-3820QM
Intel HD 4000 and nVidia Quadro K2000M
15,6" FHD RGB 1920x1080

I selected "Optimus" in the BIOS settings to activate both graphic cards. After
installing the nouveau driver on Ubuntu via 'apt-get install
xserver-xorg-video-nouveau' I was able to use my external monitor.

But! My external monitor stands physically left of my laptop, so I also set it
to the left in the settings in Ubuntu. After clicking "OK" my internal screen
turns black and the external monitor shows the correct image. But I couldn't
move the mouse to the internal screen. It persists on the external one. Without
seeing what I do I was able to open the settings window on the external screen
again to activate cloning of the screens. This works without a problem. And I
also have no problems if I set the external screen virtually to the right of the
internal one.

My version of xserver-xorg-video-nouveau is 1:1.0.10-1ubuntu2. If you need some
more information let me know.

Best Regards,
Nicolas

What happens if you just use xrandr instead of the ubuntu tool? From
your description, it sounds like it just turns off the internal
monitor instead of setting the external one to be left of it.

Hi Ilia,

with 'xrandr --output LVDS1 --auto --output VGA-1-2 --auto --left-of LVDS1' it
seems to work properly. Thank you. Do you know about a tool which integrates
well in Ubuntu? Maybe a GUI for xrandr? The other option would be to use some
bash script, which also is okay for me.

Just for your information the outputs of 'xrandr -q' and 'xrandr --listproviders':

and:

associated providers: 2 name:Intel
Provider 1: id: 0x48 cap: 0x6, Sink Output, Source Offload crtcs: 4 outputs: 5
associated providers: 2 name:nouveau
Provider 2: id: 0x48 cap: 0x6, Sink Output, Source Offload crtcs: 4 outputs: 5
associated providers: 2 name:nouveau

It looks not normal that I have three providers listed here and two of them are
exactly the same.

Sorry, I always just use xrandr directly, that way I don't have to
deal with GUI bugs and limitations. Much easier that way for me, but
do whatever works for you though.

AFAIK that's a minor bug and semi-expected. It may be fixed already in
latest versions of things. I believe it's harmless.
