kernel update problems

Postby ti479 on Mon Apr 07, 2008 11:58 pm

hello,

i recently updated (or allowed mintupdate to) update my kernel. consequently since then i have not been able to shut down my laptop. I had this problem once before when i installed mint in the first place and after many guesses on which line in the grub menu to edit, i found the right one and added apm=off and acpi=forced. since the update i have tried every thing i know to get the grub to shut down completely. i have added the apm=off and acpi=forced to every line in the menu to no avail. if there is something i havent tried or done something incorrectly (which is a likely possiblity ) then someone please tell me. any help pr experience will be greatly appreciated.

Could you clarify "not able to shutdown"?

To force a reboot, have you tried REISUB?. I haven't tried it, but apparantly REISUB has a cousin too.

Have you tried typing in a terminal:
Code: Select all
sudo shutdown now -P

hello, let me clairify,

by not able to shut down-- i mean that when i click quit and then choose shut down, my machine goes throught the motions of it , buit i wind up at a black screen with a flashing cursor.

i have not tried to use sudo shutdown- all? or is it -p. anyway, i didnt try these things because i dont want to have to do this everytime i want to shut my computer off. if i cannot get the machine to shut down properly then i will try a non-debian based distro as this seems to be a problem with Ubuntu or any of its derivitives...... i like mint the best of all the the distros that i have tried and i hate windows.....so please tell me how to correct this problem.

I don't have personal experience with your issue, so take this with a grain of salt, but it looks like your grub edit is the opposite of what it needs to be.

Best of luck, and please do report back.

ti479,

Navigate to "/boot/grub/menu.lst" and open that file. Toward the bottom of the page you will see a line like this:

## ## End Default Options ##

After that you will see several lines together that constitute your primary boot stanza. One of those will look something like this:

kernel /boot/vmlinuz-2.6.22-14-generic root=/dev/sda2 ro quiet splash

Add a space and "acpi=off" right after the "quiet splash". No quotes.

Save the file and exit. Be careful and try not to make a typo.

See if that helps you. :-)
