“Mate” and Ub 19.04 are both installed on my desktop (dual-boot). I’d like to make some minor chgs so that Ub is the default instead of Mate. This could be a good learning exercise for a newbie to Ub. (1) Is it recommended to chg the GRUB file(s) using an editor ? (2) If so, what is SAFEST way ? Thanx.
