I have Dell XPS 15 9560 hooked up with two external monitors through docking station (TB-16) and I am running Linux Mint 18 with 4.15 kernel.



I use the monitors and also the notebook screen. Everything runs smoothly until I try to set rotation on one of the monitors as I want to have it in portrait mode. When I try to set this through Display GUI settings, I get error Could not set configuration for crtc 64. I tried to set it up through xrandr and there I get error configure crtc 0 failed.



I know it is possible as I managed to get it work few times, but it was very random, after several hours of trying different combinations and so far I was not able to tell the common cause for this.



During debugging I tried to upgrade the Nvidia drivers which now shows in the "Driver manager", but I have feeling that I am still running Nouveau drivers even though in the manager there are active the Nvidia drivers. I think so because when run lsmod | grep nouveau I get results but not so for lsmod | grep nvidia.



Can it be because of not running on Nvidia drivers? Can there be any other cause for this? Please, help...
