Public bug reported:

Hi all,
i have a lenovo w520 with 14.04 but i'm unable to use dual monitor extended desktop, either with internal+external either ext vga + ext hdmi (all 3 screen are full hd 1920x1080)

When i open ubuntu display, select to not mirror, the screen change to a
distorted image, something like a big one screen fullhd very large, in
the same time some component like the right vertical toolbar seem ok;
also there is no sync between mouse arrow and real position, need to use
key to restore.

i attach a image, seem really normal but if see in the address bar you
can see is strechtced, the real state is worse, unusable.

i'm also unable to use 2 external monitor vga+hdmi (when windows can).

How i can resolve this?

thanks
