After install with acpi=off, now can't boot Ubuntu 10.04

Asked by jithin_tk

My problem is very critical. I'm using TOSHIBA SATELITE C650 (core i3, 3GB RAM, 320 SATA HDD). I had problems on installing Ubuntu 10.04 LTS using live CD, that the CD did not boot. I resolved it by pressing F6 and then select "acpi=off" .
But now after the install the same problem arises. System cannot boot in to Ubuntu, if tried same thing repeats (a black screen with full of text, and system get stucked) .

How can I fix this????

Pls help me ................

You must set this option permanent by edit the /etc/default/grub file from terminal type:

gksudo gedit /etc/default/grub

and by add your parameter to the row:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

changing it to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"

save and exit

then still from terminal type:

sudo update-grub

(if the system ask you a password give your user password, you will not see nothing when you type it, then press enter)

Then to restart the pc type:

sudo reboot

Hth
