Grub a ostatnia sesja

[infomaniak]

Witam
Pytanie dla wszystkich geeków, nerdów i innych zapaleńców z forum i nie tylko. Jako że właśnie niedawno U13.04 straciło wsparcie a do LTS'a jeszcze ponad miesiąc zainstalowałem ostatnio z ciekawości Manjaro (Arch) bo ostatnio coraz więcej i częściej o nim słychać i zauważyłem bardzo ciekawe zachowanie menu gruba na starcie systemu. Otórz grub "pamięta" ostatnią sesję i domyślnie podstawia właśnie ostatnio startowany system. Nie bardzo wiem co w konfiguracji gruba odpowiada za taki właśnie zachowanie się gruba a wolałbym móc zastosować to ze zrozumieniem. Z góry dzięki za pomoc... gotów jestem nawet wysłać browca

Poniżej konfiguracja gruba wygenerowana przez Manjaro:

Zgodnie z tym, co siedzi w sznurku podanym przez marcina, za zapamiętanie sesji odpowiadają dwie poniższe linie, które są aktywowane w twoim pliku konfiguracyjnym GRUB-a:

Kod: Zaznacz cały

[maras@asus Pulpit]$ cat /etc/default/grub
GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true 

Jakbyś kiedyś chciał zastosować to w Ubuntu, to musisz edytować plik konfiguracyjny GRUB-a:

Kod: Zaznacz cały

sudo gedit /etc/default/grub

wprowadzić zmiany i po zapisaniu zmian, zaktualizować GRUB-a:

Kod: Zaznacz cały

sudo update-grub
