[Grub2] Modification grub.cfg

[reremi]

Bonjour, je voudrais changer le splash screen de ma arch pour faire un peu plus beau , je me lance donc dans l'installation et la config de plymouth, tout ce passe bien jusqu'au moment ou je dois modifier une valeur dans grub

The kernel command line
You now need to set quiet splash as you kernel command line parametres in your bootloader. The following is an example for Grub2 and /boot/grub/grub.cfg (the legacy Grub and Lilo follow the same pattern):
linux /boot/vmlinuz26 root=/dev/... ro quiet splash

Je chroot donc mon mint ( grub est installé dessus ) j'essaye de modifier a la main mon /boot/grub/grub.cfg en vain car a chaque

celui ci se génère a partir d'autre fichier, je n'arrive donc pas a modifier ce fichu grub.cfg

Tu as la solution doublement sous le nez : ton message et le wiki. https://wiki.archlinux.org/index.php/Pl ... mmand_line

le /etc/default/grub

C'est le /etc/default/grub qu'il te faut éditer, puis relancer grub-mkconfig.

Certe, mais comment modifier ce fichier?

Edit: Bon j'arrete avec plymouth parceque ça a foutu un de ces bordel, au boot plusieur erreurs, et la maintenant plus moyen d'ouvrir alsamixer

Certe, mais comment modifier ce fichier?

Wiki:

You may also edit the file /etc/default/grub and append your kernel options to the line GRUB_CMDLINE_LINUX_DEFAULT="". To re-generate grub.cfg run:

# grub-mkconfig -o /boot/grub/grub.cfg

Tu mets tes options de kernel dans GRUB_CMDLINE_LINUX_DEFAULT et tu refais grub-mkconfig... qu'est-ce-qui n'est pas clair ?

Cela ne s'appliquera pas qu'a mint?

Cela ne s'appliquera pas qu'a mint?

J'avais oublié cette partie...
Donc, c'est ton... /etc/grub.d/30_os-prober qu'il te faut modifier, là où tu as tes entrées pour Arch (il vient de la détection automatique celui-là, non ? ... alors j'ignore comment il se comporte si tu refais une détection derrière... ... désolé, j'utilise pas grub2... ou bien tu testes en rajoutant de nouvelles entrées dans (?) etc/grub.d/40_custom si le os_prober pose problème). Puis refaire le grub-mkconfig pour mettre ton grub.cfg à jour.

Oui ça a tout foutu en l'air
