Hey,

I am having multiple problems with my p52 after following Sakaki's EFI Install Guide.
I have Windows for my work related tasks on NVMe drive, and Gentoo on the SSD.


  • CPU throttling
  • No sound card, just dummy interface
  • Power settings in GNOME do not persist, after reboot they are set to default again (i.e. screen brightness)
  • Did not come to NVIDIA PRIME setup yet, but I am assuimg I will have problems
  • WiFI only works when compiled into kernel, but it should be vise versa
  • Whole experience on DE feels kinda "clunky", I've probably missed something during kernel build


I was trying to fix my sound issues by enabling all snd_intel_hda drivers as modules and also built in, but then I just cannot go past the plymouth screen. I am just assuming these issues are related to dual GPU setup, so should I start with the PRIME configuration frist?
CPU throttling can be solved by disabling turboboost, but this just seems like a workaround, not a solution. Is there any other way?
Have no idea why WiFi only works as built-in driver.

Code:
lspci -nnk

dmesg
.config
emerge --info

Keep in mind this is "work in progress" build, so kernel is far from optimal, but any advice would be highly appreciated, even if not related to my questions above.
