[Risolto] Kernel aggiornato ma non in esecuzione

auanagana · Messaggio da **auanagana** » sabato 3 aprile 2010, 19:14

Premetto che tutto funziona perfettamente. L'unica cosa che non riesco a capire è che nonostante gli ultimi aggiornamenti, il kernel in uso è il 2.6.32-16-generic-pae, mentre nella sezione di boot è presente il 2.6.32-19-generic-pae oltre a versioni precedenti compresa quella citata.

Codice: Seleziona tutto

2.6.32-16-generic-pae #25-Ubuntu SMP Tue Mar 9 18:03:39 UTC 2010 i686 GNU/Linux

Da synaptic risultano installati tutti. Non saprei da dove iniziare con il nuovo grub per caricare l'ultimo kernel. Ad abundantiam, la macchina in uso non è virtuale.
Ringrazio per eventuali suggerimenti.

Fatto come da indicazione ma rimade sempre il .16 anche dopo un prudenziale riavvio. Se ci riesco provo a postare per maggior chiarezza la configurazione di grub

Dal menu.lst il .19 appare... ...per capire meglio, il tuo problema è che pur selezionandolo all'avvio ti ritrovi sempre col .16 (ma parrebbe alquanto strano) o che non ti appare proprio nella schermata di Grub?

Confermo che tutto funziona perfettamente.
Grazie

Ciao,da quello che vedo hai sia Grub-legacy che Grub2, e in pratica il sistema si avvia con Grub2 ma mette i kernel che aggiorni in Grub-legacy,prova in questo modo,dai nel terminale

Codice: Seleziona tutto

sudo apt-get --purge remove grub

poi sempre nel terminale per sicurezza dai

Codice: Seleziona tutto

sudo apt-get install grub-pc

e

Codice: Seleziona tutto

sudo apt-get install grub-common

per questi ultimi due comandi è probabile che ti risponda che sono già installati,comunque come ho già detto per sicurezza falli ugualmente,quando hai finito sempre nel terminale dai

Codice: Seleziona tutto

sudo update-grub

e riavvia il pc.

Perfetto, ho eseguito pedissequamente quanto mi hai suggerito ed ora si avvia con il kernel corretto.
Grazie ^alessio^ e Buona Pasqua. Ovviamente gli auguri sono estesi a tutti gli amici del Forum, in particolare a coloro che si sono prodigati nel risolvere questo problema.
