ubutnu mi často nenabootuje

[vin.cent]

dobrý večer vespolek, potřeboval bych pomoct, protože se můj systém velmi často zasekává před nabootováním. Musim potom udělat "tvrdý reset" a na druhý pokus už to jde. Občas to potom i kontroluje konzistenci disku. Poslední dobou se mi to stává velmi často, ale začalo to, když jsem upgradoval na Ubutnu 10.04 LL. Mohl byste někdo prosím mrknout do boot_info, jestli tam není nějaký problém? V příloze systémové info. Díky, v.

A kde se ti to sekne,jestli jako mě,na té obrazovce s logem Ubuntu,jak tam běhají ty tečky,tak tohle 10.04 dělá docela často a vím jen o dvou řešeních (o třech,pokud máš grafiku nVidia),takže:

1)čistá instalace 10.04.1 (update)
2)upgrade na 10.10 (nevymizí,ale minimalizuje se to tak na jeden start ze 100)
3)vložit do grubu parametr nomodeset (ale jen pro nVidia grafiku)

[vin.cent]

Právě že ne, většinou se to sekne uplně na začátku v prvních vteřinách, kdy je obrazovka ještě černá, anebo ve chvíli, kdy tam naskočí hardwarový info. Každopádně ještě před samotnym bootovánim, k logu Ubuntu se to vůbec nedostane.
