DVI-I being read as DVI-D and i have no picture

[Lakner Máté]

Hi!

I'm using Radeon R9 380X graphics card with two monitors. Before installing the radeon drivers, each of the monitors work properly. But after this, the DVI-D output is being read as DVI-I, and monitor attached to this port says "No signal". It only has a d-sub VGA input. The other monitors works fine.

Here are the outputs of the xrandr command:

Before installing the drivers:
