Asus K55n laptop Arch Linux problems and solutions.
Raw
Asus_k55n_linux_problems
On kernel 3.14.14
Date: 05/15/2014
** Basically my laptop only has the base arch packages + all gnome related stuff (And a few other misc, apps).
** It also has a bunch of problems right out of the box, so I'm documenting my found solutions to them here
** for my own future reference and hopefully someone elses benefit.
=============
= Solved
Problem: Sound starts muted.
Solution: Install Alsa-Utils and make sure to disable auto-mute.
Problem: Can't adjust backlight
Solution:
1) run "modprobe asus-nb-wmi"
2) add "acpi_osi=\"!Windows 2012\" video.use_native_backlight=1" kernel parameters.
Problem: Grub doesn't boot
Solution: install it into /boot not /boot/efi (assuming that's where you mounted your boot partition.
=============
= Un-Solved
Problem: When the laptop enters sleep mode and resumes, the screen stays black.
Details: The laptop is fully awake, as I can get into TTY2 and blindly login + reboot.
If plugged into a second monitor (my tv) the second monitor actualy turns on and is fully functional.
Problem: Gnome doesn't detect that the laptop is plugged in when the battery is full.

I have added an entry for ASUS K55N laptops to fix most issues along with your unsolved ones. Hopefully it will be patched upstream too. 😄
