Fortunately, all of the failing ACPI methods are optional, and there are
good chances that Linux / Ubuntu will work without them. There are three
types of devices *might* be affected according to the error messages:
1. USB (\_SB.PCI0.XHC.RHUB...)- but USB ports and devices should just-
work without BIOS code, which are usually for OEM customization.
2. Touchpad (\_SB.PCI0.I2Cx...) - error messages are reported for i2c-2
and i2c-3, but it is likely the touchpad is connected to i2c-1. Please
check whether you are experience problems with your touchpad.
3. Switchable graphics (\_SB.PCI0.PEG0...)- but error messages are
"AE_ALREADY_EXISTS". lspci also shows no discrete VGA present on this
system, and nothing to worry about.
