Wolny rozruch Ubuntu 13.10 na szybkim sprzęcie

[Nitrox]

Niedawno zrobiłem lekki upgrade kompa, procek Intel Xeon E3-1230V3 (architektura właściwie taka sama, jak w Core i7, Haswell - tak, gdyby ktoś nie wiedział i od razu krzyczał, że głupi jestem, bo to do serwera - a gucio, bo nie tylko), 8GB RAM, dysk WD Red 1TB. Windows 7 na tym wstaje do pulpitu w około 20 sekund, programy takie, jak FF startują błyskawicznie, a jest on przecież dodatkowo "dociążony" Bitdefenderem, który lekkim antywirusem przecież nie jest.

No i tak oto postanowiłem sprawdzić, jak się będzie zachowywał na tym sprzęcie najnowszy ubunciak i w zasadzie przeżyłem szok, bo chodzi wolniej, niż na moim starym kompie (Athlon X2 4200+, 4GB RAM, dysk 160GB z 2006 r.). Tzn. uruchamia się od momentu wybrania w GRUBie wpisu "Ubuntu" do ujrzenia pulpitu w ok. 50-60 sekund, czasami trwa to nawet 2 minuty, jak mu coś odbije. I tak jest od początku po instalacji. Doinstalowałem aktualizacje najnowsze, ale to nic nie zmieniło. Ponadto programy takie jak FF jakoś tak wolno się uruchamiają, generalnie czuć, że strasznie ciężko cały ten system chodzi. Żeby było ciekawiej, Ubuntu 13.10 z pendrive'a uruchamia się o jakieś 50% szybciej tak na oko.

Co tu się dzieje? Jak to jest, że Windows 7 z wymagającym antywirusem startuje o niebo szybciej, niż Ubuntu, na którym nic jeszcze nie zostało zainstalowane? Da się coś z tym zrobić, czy po prostu ten system tak już ma?

Doinstaluj program o nazwie bootchart, będziesz miał dokładny zapis i wykres tego co i jak długo się uruchamia.

Kupiłeś sprzęt pod Linuksa, czy kupiłeś sprzęt, a dopiero potem pomyślałeś o Linuksie? Pytam, bo to częsty błąd... Powodów, dla którego jeden system wstaje szybciej jak drugi, może być wiele. Zacznij od przeglądnięcia logów w systemie - dmesg może wiele ukazać:

dmesg

Więcej o dmesg:

Kod: Zaznacz cały

man dmesg

Sprawdź, co potrzebuje najwięcej czasu, a potem pytaj google wklejając całą linię. Tak najszybciej się dowiesz, co w twoim sprzęcie piszczy/kuleje...

Oto, co "wysmażył" bootchart:

A tutaj dmesg:

Nic z tego nie rozumiem. Jestem windowsowcem. Nie składałem komputera patrząc na to czy Linux będzie na nim działał. On miał odpalać przede wszystkim ciężkie windowsowe programy typu Adobe After Effects i gry, a Ubuntu zainstalowałem, bo po prostu wpadł mi taki pomysł do głowy - chciałem sprawdzić, jak będzie działał na tym sprzęcie.

Ale Ci się szybko uruchamia!!! U mnie dochodzi do

.
Z bootchartem Ci nie pomogę, bo się też nim bawiłam i nic nie skumałam, ale w tym przypadku "windowsowiec" kojarzy się jako synonim... no, leń powiedzmy! ;p Po pierwsze, jak chcesz, żeby Ci tu ktoś pomógł, to wklejaj wszystko tu, między znacznikami CODE. A po 2. przyjrzyj się rezultatowi dmesg, w pierwszej chwili nic nie widać, ale w końcu zauważysz, że z przodu leca cyferki po kolei i nagle masz skok.

A-ha! Kopiujesz "Warninga", idziesz do wujka i hop! Lądujesz np. tu: http://ubuntuforums.org/showthread.php?t=2148342. Dalej dłub sam.

Dzięki za dobre chęci. Nie jestem leniem. Po prostu mam masę innych zajęć i nie mam z reguły czasu/jestem zbyt zmęczony, żeby sam kombinować. Miałem nadzieję, że zainstaluję i zapomnę, ale to oczywiście nie przeszło. Z Ubuntu zawsze coś musi być nie tak, zawsze gdzieś trzeba pogrzebać, podłubać, a ja jestem zawalony swoją robotą. Dobra, sprawdzę, co tam piszą na tamtejszym forum.

//edit
Wg tamtego forum zainstalowałem pakiet libnss-myhostname. Teraz dmesg wygląda tak:

Niby lepiej, ba, o wiele lepiej, ale... nic to nie dało. System nadal startuje tyle, ile startował. Nie widzę żadnej różnicy. Na starym kompie mi się szybciej uruchamiał.

Jak się uruchamia system, to po naciśnięciu strzałki w dół, zamiast bootscreena mam czarny ekran przez dłuższą chwilę, a potem nagle pokazuje się ściana tekstu, jakby jakieś kolejne sekwencje uruchamiania i tam dosłownie na ułamek sekundy przy jednej linii pokazuje się czerwony napis [fail], po czym przechodzi do ekranu logowania. Tak myślę, że może tutaj tkwi przyczyna. Coś próbuje zrobić przez dłuższą chwilę, po czym nie udaje się to coś i przechodzi dalej. Da się jakoś sprawdzić ten log? Bo to wszystko pokazuje się na ekranie dosłownie na moment, po czym znika przechodząc na ekran logowania i nie idzie tego przeczytać.

Ten czerwony fail to niekoniecznie przyczyna. Tak może wyglądać na przykład próba (rezygnacja) z uruchomienia domyślnych sterowników grafiki, kiedy w systemie jest zainstalowany przez użytkownika inny sterownik.
Podobnie wygląda sytuacja z programem gufw (o ile dobrze pamiętam) do konfiguracji zapory sieciowej. Przy starcie pokazuje fail, a zapora i tak działa.
