Picture of the displays in question
I have a lenovo T430 (see attached dmesg, etc.) with 'optimus'.
I wish to attach two external monitors. Helpfully, these are wired to the
nvidia chip, and as such I am using intel-virtual-output to drive these
screens.
However, it appears there's something funny with the randr proxy. When I enable
one screen, everything works as expected. When I enable two screens, they are
tied together in strange ways:
1) Rotation of one virtual screen affects the other virtual screen
2) The virtual screens are always a 'clone', and when I would expect there to
be 'extended' desktop, the (same) view on both monitors pans to follow my
cursor.
Please see attachments.</pre>
