There are a couple of strange issue with Ubuntu MATE’s GRUB menu. The first one, which I asked about here, has to do with accessing the menu. When I hit shift
immediately after the startup screen, GRUB loading
(or something like that) briefly appears, then I get a blank screen, and then the normal boot process re-commences and I find myself with the normal LUKS password prompt (I’m using full-disk encryption). One (not entirely satisfactory) way to handle that is to “force” the GRUB menu to appear by commenting out the line GRUB_HIDDEN_TIMEOUT=0
in /etc/default/grub
.
Second issue: I have my system set to boot in non-graphical mode, so I wanted also to set GRUB to non-graphical mode as well by uncommenting the line GRUB_TERMINAL=console
. However, when I do that I get an error message: error: no video mode activated
. Is there something with the MATE version of GRUB that only allows for a graphical GRUB menu?
