I know this question has been asked already, but nothing I found on the internet solved my problem.
I have 2 monitors connected to a docking station. I have an integrated Intel Graphic Card
Monitor 1: VGA
Monitor 2: Display Port (DP)
On windows the monitor is working fine. If I start my Ubuntu session with the DP monitor branched I get the error: The system is running in low-graphics mode
I tried to follow the solution to this question but it didn't work: How to fix "The system is running in low-graphics mode" error?
The one over display port is not detected, even if when I branch/debranch the cable the monitor wakes up but then it says NO SIGNAL and it goes to sleep.
This is the output of my xrandr

What can I do?
