Unable to change resolution in grub

[tolgaerok]

ive added the following into grub as per your instructions but the resolution dosnt change to 1920 (Fedora 36 - grub 2.06??) but thankfully the theme does show. I have unicode.pf2 in the/boot/grub2/fonts

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="gfxterm"
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_GFXMODE="1920x1080x16"
GRUB_CMDLINE_LINUX="zswap.enabled=1 rhgb quiet mitigations=off rd.driver.blacklist=nouveau selinux=0"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG="true"
GRUB_THEME="/boot/grub2/themes/fedora/theme.txt"

Ran your recommended grub2 updater: sudo grub2-mkconfig -o /etc/grub2.cfg && sudo grub2-mkconfig -o /etc/grub2-efi.cfg && sudo grub2-mkconfig /etc/grub2-efi.cfg

Also ran: sudo sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Grub does not change to the desired resolution and is all big fonted?

Before we begin, follow these instructions to reinstall GRUB. The last command you ran has long been deprecated.

Maybe try commenting out the GFXmode line entirely? My config does not contain that line and auto-adjusts the resolution according to my monitor.

Reinstalling the grub as stated on the fedora website will other os be picked up I.e. windows

Solved: Resolution now sets to 1920x1080

Followed instructions as follows:

rm /boot/efi/EFI/fedora/grub.cfg
rm /boot/grub2/grub.cfg

sudo dnf reinstall shim-* grub2-efi-* grub2-common

Edited /etc/default/grub2 and added:

GRUB_DEFAULT="saved"
GRUB_DISABLE_SUBMENU="true"
GRUB_GFXMODE="1920x1080"

Edited /boot/grub2/grub.cfg and changed

if loadfont $font ; then
  set gfxmode=auto

to

if loadfont $font ; then
  set gfxmode=1920x1080
