Chciałbym wiedzieć, jak utworzyć powitalny dla Ubuntu Maverick z komunikatami rozruchowymi wyświetlanymi podczas uruchamiania, a także pasek postępu i obracające się logo.
Lub, jeśli to możliwe, jak edytować panel powitalny, który ma już obracające się logo i pasek postępu, i dodawać do niego komunikaty rozruchowe.
To jest temat, który chciałbym edytować:
i chciałbym coś takiego:
lub to, co dokładnie chcę utworzyć:
udało mi się znaleźć tę stronę internetową, która zawiera wiele przydatnych informacji, ale mam trudności z jej zrozumieniem. nie robiłem wcześniej żadnego skryptu!
Utwórz własny ekran powitalny z przewijanymi komunikatami rozruchowymi
i to jest kolejna strona internetowa, która może pomóc w tworzeniu skryptów
to jest skrypt dla paska postępu w widoku powitalnym:
#----------------------------------------- Progress Bar --------------------------------

progress_box.sprite = Sprite(progress_box.image);
progress_box.x = Window.GetX() + Window.GetWidth() / 2 - progress_box.image.GetWidth() / 2;
progress_box.y = Window.GetY() + Window.GetHeight() * 0.65 - progress_box.image.GetHeight() / 2;

progress_bar.sprite.SetImage (progress_bar.image);
}
}
Plymouth.SetBootProgressFunction(progress_callback);
OK, więc przeprowadziłem znacznie więcej poszukiwań i mogłem dowiedzieć się nieco więcej o Plymouth.
to są strony, które uznałem za przydatne. Przewodnik tematyczny w Plymouth Istnieją cztery części tego artykułu, które musisz przeczytać, aby uzyskać sedno tego, co robimy. (Porównywałem ich skrypt ze skryptem dla mojego powitania, aby zrozumieć, co to jest, zalecam zrobienie tego, jeśli ktoś ma pójść w moje ślady.) Skrypt Plymouth Ok, ten link ma 2 strony, które musiał przejść przez nich, aby zrozumieć, co robić . Okazało się, że chodziło o to samo, co ja, czyli o przekierowanie komunikatów rozruchowych do Plymouth splash, gdzie mam już obracające się logo, tło, pasek postępu.
Musiałem więc edytować /lib/lsb/init-functions
plik i sprawić, aby wysyłał komunikaty o błędzie rozruchu / sukcesie itp. Do Plymouth poprzez dodanie tego akapitu

Do tej pory nie byłem w stanie przekazać wiadomości do Plymouth, ale lepiej zrozumiałem, jak działają skrypty Plymouth!
Nie wiem, co jeszcze mam zrobić, aby działało! mając nadzieję, że ktoś tu może mi pomóc
