I am new to this forum. i have had my rounds getting linux installed on a WD mypasswort ultra 1 TB external HDD. I finally have it successfully, well for the most part, running on via legacy boot onto an acer chromebook c720. my problem now is that i cannot get the touchpad mouse to work. i really am not trying to mess anything up now that i have this working. any more info you need let me know but if anyone could help me get this working it would be much appreciated.
