[Nouveau] Second Monitor left of internal monitor turns internal monitor black

Thu Apr 24 11:55:44 PDT 2014

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:

nicolas at tp-w530:~$ xrandr --listproviders
Providers: number : 3
Provider 0: id: 0x6f cap: 0x9, Source Output, Sink Offload crtcs: 4 outputs: 3
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.

Regards,
Nicolas
