This wiki contains in code wrong path:
https://wiki.manjaro.org/index.php?title=Make_GRUB_menu_%26_boot-up/down_fonts_bigger
wrong /usr/share/fonts/TTF/dejavu/DejaVuSansMono.ttf
correct /usr/share/fonts/TTF/DejaVuSansMono.ttf
Plus i get errors that are just an Information??
grub-mkfont --output=/boot/grub/fonts/DejaVuSansMono18.pf2 \ --size=18 /usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf
–size=18 kann nicht geöffnet werden, Index 0: Fehler 1: cannot open resource
/usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf kann nicht geöffnet werden, Index 0: Fehler 1: cannot open resource
p.s.
The better way seems to be adjust grub resolution by
edit /etc/default/grub
The resolution used on graphical terminal
note that you can use only modes which your graphic card supports via VBE
you can see them in real GRUB with the command `vbeinfo’
GRUB_GFXMODE=1280x1024
