Ubuntu 20.04 on ASUS TUF A15 (FA506IV)

ubuntu_on_asus_TUF_A15_FA506IV.MD

Installed using lived cd

Needed to add the nomodeset option to grub to correctly boot

After boot edit /etc/default/grub and add the nomodeset to the line with GRUB_CMDLINE_LINUX_DEFAULT.

Run this to make it persistent:

sudo update-grub2

The RTX 2060 was not detected by default even when installed the nvidia drivers.

Also thermal fans were working all the time.

After a little bit of reading i found no thermal support for the 5.4 kernel.

Updating the kernel to 5.9.10

First installed the Ubuntu Mainline Kernel Installer from here --> https://github.com/bkw777/mainline

Once installed run mainline-gtk and selected the 5.9.10

Hit install and wait for all the process to finish.

Now you need to reboot but fist you need to disable secure boot from the BIOS if not the boot wont work as linux kernel is not signed.

So wait for reboot and press F2 (keep it pressed until bios config start). Go to advanced and disable the secure boot, save and exit.

Now is going to boot, you then can check the version of ther kernel uname -a The fans are no longer spining all the time.

You can install now the nvidia drivers and it will work! (use the additional drivers from ubuntu)

AUDIO

I had problems with the many audio devices detected

So, first get a list of all of them from alsa

$ aplay -l

Output:

**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 9: HDMI 3 [HDMI 3]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: Generic_1 [HD-Audio Generic], device 0: ALC256 Analog [ALC256 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

Now select the card 2 to do that just create a file called /etc/asound.conf

and put this inside:

pcm.!default {
    type hw
    card 2
}

ctl.!default {
    type hw           
    card 2
}

HDMI external display support

Go to /etc/default/grub and replace the nomodeset for amdgpu.exp_hw_support=1

This will allow to use the AMD vide card, not the NVIDIA.

Follow this for full config with nvidia: https://askubuntu.com/questions/1244376/cant-get-internal-and-external-monitor-working-simultaneously-with-20-04-on-lap

Work with close lid

I love to work that way so:

go to /etc/systemd/logind.conf and add on [login] section this:

HandleLidSwitch=ignore

you are welcome.
