Laptops - MSI GE62 6QC

Weird problems with keyboard. Also touchpad is not working.

List IM modules:

env | grep -i -e im -e lang

result

LANG=en_GB.UTF-8
LANGUAGE=en_GB:en
LC_TIME=en_GB.UTF-8
HISTTIMEFORMAT=%Y-%m-%d %H:%M:%S

Set all ibus to xim. For example:

export GTK_IM_MODULE=xim

Steps

disable FastBoot (both in UEFI and Windows 10), SecureBoot and SpeedStep (the latter two shouldn't matter but it won't hurt to disable them anyway)
install with nomodeset boot option
reboot and got an instant hangup
reboot again with nomodeset
update everything to get the latest stable kernel (by now 4.2.19, stock 4.2.12 works as well)
install latest Intel graphics stack (https://01.org/linuxgraphics/downloads)
install NVidia properietary driver. Beware - after this nomodeset may not work again so be prepared for a clean install if something goes wrong.

reboot. It will either hang up instantly or it will boot normally. It hung up in my case.

The thing now is to get it to boot once so the drivers can be configured by X server

-do NOT add i915.preliminary_hw_support as it's not needed anymore

-from now on delete quiet and splash from boot options every time you add something there to see what errors you get.

-firstly try

intel_idle.max_cstate=1

as a boot option

-if that hangs up try

acpi=noirq or acpi=hd or acpi=off

The last one gave me a first proper boot. After a restart it didn't boot again giving bumblebee errors.

this time boot with

intel_idle.max_cstate=1

If it works add this line to grub permanently. This way you will get a stable system using i915. For now I didn't try to force it to use nvidia.

Try to boot with only

intel_idle.max_cstateate=1

Do not disable ACPI anymore. Also try to re-enable SpeedStep in UEFI.
