I have installed Ubuntu 16.04 in Legacy Mode on a MSI PE60 6QE (Nvidia GTX960M, I7 Skylake). However, it is not working well. Secure boot and Fast boot are not enabled.
I have tried all these steps with the "Prime select intel", nvidia drivers 361 and 364 options; and also trying with the 4.4-021 and the recent 4.6 kernels.
I can make it work with "ACPI=off", not with "ACPI=ht". It works well, but it is not a secure mode, I think, as I have to use a lot of CPU power. Funny thing, the touchpad is not detected with this option, and the same happens with the Fn+Key combinations. External mouse is detected and works well.
I can make it work with the "nomodeset idle=nomwait" option. It enters however in the login screen loop. With this option enabled, the touchpad is detected. If I use the nvidia driver 364, the refresh of the screen is very low, it "blinks" a lot. I also get the "wifi: unsupported splx structure" error at the beginning of the loading screen and continuous "pcieport... : receiver error". does not help, also.
If I use the "nomodeset idle=nomwait ACPI=off" I can go to the desktop menu... although it does not load, I just can see some icons while they blink among different positions in the screen.
Please, im desperate. What can I do? Can someone help me? I am really in a hurry! 15.10 does not work, either! Should I try with 14.04? I need to run some scripts asap :/
Thank you all.
