I have assigned a unique GRUB_BACKGROUND='someimage.png' and it works fine.
However, at times I need to troubleshoot issues during boot time. I need to be able to press a hotkey to see the actual boot loading text.
I have tried ESC, Right Ctrl-S and many other combinations but nothings working. I cannot locate the correct key combination to accomplish this.
What sayeth the group ?
Using Ubuntu (Xubuntu flavor) 18.04
