How to get 'X Screen 1' up
I installed Fedora 27 on a desktop with 4 monitors and 2 NVIDIA cards:
# lspci | grep -E "VGA|3D"
01:00.0 VGA compatible controller: NVIDIA Corporation GP107 [GeForce GTX 1050 Ti] (rev a1)
02:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1)
After the install, all 4 screens were working properly. The whole UI was flickering a lot so I decided to look into the vendor's drivers. Following the steps from this tutorial I installed the NVIDIA driver and dropped the nouveau version.
NVIDIA-Linux-x86_64-387.34.run
I confirmed this driver supports both cards in this PC.
The whole installation was OK and now I have nvidia-settings app. Now the issue: The main video card which has 3 screens work fine. The forth screen, connected to the second card (GT 610) although detected by the NVIDIA X Server Settings, doesn't show up.
The NVIDIA X Server Settings (nvidia-settings) view, the working screen hooked to the first card:
And the faulty one:
Any idea how can I get the forth monitor working?
