Public bug reported:

I have a Toshiba Universal dock (Dynadock using USB3) with keyboard,
mouse, ethernet and display attached.

When I use a USB OTG cable with the Nexus 7, the keyboard, mouse and
ethernet work perfectly but the screen does not.

Would dearly love to get the tablet working when docked so I can
potentially carry only one device.

I have also tested with Raring on my laptop (the machine that I am submitting 
this bug with) and get the same outcome.
So I guess that means it's a kernel issue rather than Nexus 7 specific?
