I just got a brand new laptop. And of course, as any good dev would do, I tried installing Ubuntu on it. I ran into a huge issue, where the firmware for the iwlwifi device/drivers. It kept failing post-boot with a UCODE=-110 or something like that. It took me three hours but I finally fixed it. It ended up having to do with iwconfig's power management. You can disable this by doing the following in a terminal.
- Boot into Ubuntu
- After login screen appears, press
Ctrl+Alt+F2. (You might need to hold down the function key as well, which would beCtrl+Alt+Fn+F2). - Once at the terminal screen, login with your username and password.
- Next, enter the following command:
sudo -i - This will prompt you to enter your password again, and by doing so you will be logged in as root.
- Now, enter
echo "options iwlwifi power_save=0" >> /etc/modprobe.d/iwlwifi.conf reboot- In the grub boot menu, select
Advanced Options - select
ubuntu-linux-5.0.28-generic
Additional Steps
There are a few additional things I did that I am uncertain as to whether or not they might have had an impact on my success.
- Edit grub and add
arm=offto GRUB_DEFAULT_COMMAND. - Boot into your ubuntu installation media, and open a terminal.
sudo apt updatesudo apt upgrade-dist
- Boot into the grub of the installation media, and type
con your keyboard- This will bring up a simple grub terminal
- enter
acpi=off
That's all I've got folks. I thought I'd write this down just incase anyone else ran into trouble just like me. Cheers!
