Just discovered on my dual boot Manjaro stable system-- 5.9 kernel, 5.20 desktop, bare metal… that on bootup --ctrl+alt+f2 no longer works. Hmmm. In looking at /etc/default/grub, line 18- “Uncomment to use basic console” is GRUB_TERMINAL_INPUT=console. Line 21, “Uncomment to disable graphic terminal” is # GRUB_TERMINAL_OUTPUT=console. Either of these cause the problem or could it be somewhere else. From the logon screen there is no more ctrl+alt+f2 to get to a CLI log on and I consider this dangerous…
Second question- Where does one uncomment in Grub to disable system startup from looking for a hibernation device that is no longer there. One of the installations on this dektop sits and looks for the UUID of a hard drive that doesnt exist any longer.
/etc/fstab does part of it. Delete the disk entry by UUID in fstab. Cant find the place in Systemd to change where it totally disappears.
Masked the unit(swap) in sysctl…solved.
And another question-- when the machine is started, grub allows one to make a selection of which OS to start, yes? So I select one from the list and press the enter key. I am assuming Grub’s job is done as it looks at the hard drive or partition that the selected operating system resides on. At that point to what controls booting? I am assuming that Grub is out of the picture and various files and subroutines on the booted operating system take control to boot, yes¿?
Edit… Looking at the Arch Wiki–it looks like Grub hands things off to systemd to start the os…Didnt do my research on this part my apologies.
