Problems with multihead
Hi everyone
I got problems with my mutlihead setup. I'm currently using Xorg + i3.
The point is: My "right" screen is working properly. On the left screen, i got extremly low FPS (around 10, I'd guess). Furthermore the left screen is flickering massivly.
I got a special hardware connection to the monitors. I hope this "graphic" is comprehensible:
MAINBOARD (DVI) ----- (HDMI) RIGHT MONITOR
MAINBOARD (HDMI) ----- (HDMI) HDMI-SWITCH (HDMI) ------ (HDMI) LEFT MONITOR

|
DED GPU (NVIDIA) (HDMI) ----- |

EndSectionDo i need to right a custom configuration for the monitors? I tried one and put it in /etc/xorg.conf - but it didn't work. (Maybe i fucked up with the syntax tho).
I'd be glad if anyone give me a hint on whats going wrong.
Thanks in advance and have a nice day
