Ubuntu 16.04
ASUS
K501UX-WH74
Everything is working 100% fine for me, after doing the following fixes. Alternatively, once installed, use the this script: https://github.com/W-Floyd/ASUS_K501...stem-Config.sh
Edit: It occurs to me that I have not documented any boot issues other than removing the splash option. I had changed BIOS settings beforehand, so I cannot say what issues you may encounter otherwise. YMMV.
Live boot issues
Hold escape while booting to choose boot source (as usual)
Choose your media, then press 'e' upon entering the grub selection screen.
Remove the ‘splash' option, then press F10 to boot.
Tested on Linux Mint 17.3 Xfce, elementary OS Freya and Ubuntu 16.04
Instability (Random hangs)
I expect you should update the kernel. Skylake support maybe?
Experienced on elementary OS Freya, not tested a new kernel on that OS. Ubuntu 16.04, with a much newer kernel, is perfectly fine
Scaling (4K support)
Ubuntu 16.04 - System Settings -> Displays -> Scale for menus and title bars - Adjust to taste (2-2.5 seems good – I use 2.12 or 2.0)
In my experience, Unity does the absolute best job of scaling for 4k. Next would be Cinnamon, or KDE.
Wireless network card not working
To fix this (at least partially), do the following:
Code:
echo "options asus_nb_wmi wapf=4" | sudo tee /etc/modprobe.d/asus_nb_wmi.conf
And restart.
Wifi should now work.
But the Fn+F2 toggle will still not change anything yet.
Try the following to fix that.
Edit /etc/default/grub
Code:
sudo nano /etc/default/grub
Change
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="
Save and exit, then run
and reboot.
Your Airplane Mode key should now function correctly.
Wired connection also works after this
Brightness keys not working
If you have already fixed the network card issue, the screen brightness button should now respond (though maybe not function yet).
If you have not already done the network fix, do it now:
Edit /etc/default/grub
Code:
sudo nano /etc/default/grub
Change
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="
Run
and reboot.
At least in my case(Ubuntu 16.04), the brightness popup would now appear, but with no change in brightness. To fix this, do the following:
Edit the grub config file:
Code:
sudo nano /etc/default/grub
Add another boot option. So
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="
will now be
Code:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi= acpi_backlight=native"
Save, exit, and update grub
Restart computer.
Viola! You may now change your brightness as expected!
