Do you have a Bliuetooth adapter installed? I see nothing in your terminal results that shows that one is installed

Actually you can add acpi=off alongside "quiet splash" in /etc/default/grub

Code: Select all

xed admin:///etc/default/grub

Make changes, save file

Code: Select all

sudo update-grub
