I have got 2 monitors, and everything worked fine with Lubuntu where i had 4.4.0-31 low latency as kernel, just installed ubuntu 19 with its new 5.0.0-generic kernel and now the second monitor gets recognized but doesnt receive signal.
When i had 4.4.0 as kernel the second monitor got recognized as a DVI-I-1 and everything worked fine. I don't know why, but now xrandr says it comes from DVI-D instead of DVI-I (it's actually coming out from DVI-I through an adapter)
Is there any method to change the display output on xrandr in a forced way? Even if im not sure that would solve the problem.
