Change font grub on boot

Fedora Linux Configurazione
#1

Buongiorno a tutti, ho un Dell XPS-13-9370 che al boot ha una risoluzione di 3840x2160 quindi qualsiasi azione si vorrebbe intraprendere (es. selezionare un diverso kernel) è praticamente impossibile perchè i caratteri sono così piccoli che risultano illeggibili.
Qualcuno riesce a darmi un aiuto?

Prove effettuate:

$ uname -a
Linux xps-13-9370 5.6.8-200.fc31.x86_64 #1 SMP Wed Apr 29 19:10:01 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

Aggiunto al file /etc/default/grub

GRUB_GFXMODE=1024x768,auto
GRUB_GFXPAYLOAD=keep

ricreato grub:

$ grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

#2

Per la community ho trovato la soluzione dopo 1 anno e mezzo visto che il primo post lo avevo aperto nel dicembre 2018 ma nessuno era riuscito a darmi la soluzione.

Modificare file /etc/default/grub:

  • commentare: GRUB_TERMINAL_OUTPUT=“console”
  • inserire:
    GRUB_TERMINAL_OUTPUT=“gfxterm”
    GRUB_GFXMODE=1024x768,auto
    GRUB_GFXPAYLOAD=keep
$ vi /etc/default/grub

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
#GRUB_TERMINAL_OUTPUT="console"
GRUB_TERMINAL_OUTPUT="gfxterm"
GRUB_CMDLINE_LINUX="resume=/dev/mapper/fedora_localhost--live-swap rd.lvm.lv=fedora_localhost-live/root rd.lvm.lv=fedora_localhost-live/swap rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true
GRUB_GFXMODE=1024x768,auto
GRUB_GFXPAYLOAD=keep

Ricreare file grub

$ grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Potete chiudere il post come risolto, grazie

Buona giornata a tutti
