Dear Maintainer,

I switched to SDDM rapidly when it became available.  All was OK.
Since a recent update (I suppose 0.11 -> 0.12), login is hardly
possible.

I have 2 screens:
 - A 1280px wide at left (VGA)
 - A 1920px wide at right (DVI)

When the 2 screens are connected:
 - the login form is centered on the right screen,
 - the right part of the right screen is black, and I can only
   see a part of the login form.  The non-black part of the
   display is ok.

It seems to me the non-black part could be 1920px wide...

Once logged in, display is OK on both screen.

Merci,
Benoit

I have a very similar setup and the same problem. Interestingly
enough, the problem goes away if I configure Monitor1 as
"RightOf" instead as "LeftOf". Then the sddm greeter is on the
primary screen, and the other one stays black.
