Public bug reported:
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:
