Installing Ubuntu on LG Gram 17 (2019)

Setup instructions to facilitate installation of Ubuntu on LG Gram 17.

Performed with Ubuntu Budgie 19.10 on a LG 17Z990-R.AAS7U1 installed on a SATA SSD.

1. At boot, spam F2 to enter BIOS

2. Find security settings in the BIOS under the Security tab and click on Secure Boot Configuration

3. Disable secure boot

4. Modify boot order to prioritize USB drive. This step assumes you've made a bootable USB drive with an Ubuntu distribution. If you haven't made a bootable USB drive from an ISO, try Rufus.

5. Save and exit the BIOS, upon reboot spam e, and make sure to add pci=nommconf before quiet nosplash

6. At this point, you should be in the normal Ubuntu installation sequence. Install Ubuntu.

7. Upon reboot after initial Ubuntu installation, to get back into the OS you will likely need pci=nommconf by spamming e

8. Finally once logged into Ubuntu, modify the boot permanently with your editor (vim, nano, etc)

vim /etc/default/grub

GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="pci=nommconf quiet splash"
GRUB_CMDLINE_LINUX=""

After adding pci=nommconf before quiet splash then save changes and afterwards run

sudo update-grub

At this point, you should be good to go and never have to bother with the pci=nommconf setting again.
