Standby on Samsung N150

[Inflame]

I have updated Ubuntu 10.04 to 10.10 with Voria's samsung-tools, etc. When I try to return from standby the display will not turn on. At the same time netbook is working.
Help me, please.

[Inflame]

Rather suspend, not standby.

This is Maverick bug. No fix released yet. Same problem in >this< thread.

Yep, I have exactly the same problem. Just updated to 10.10 and I can't wake my Samsung N150 plus anymore.

Hello everybody,
I've got exactly the same problem and i would like to know if someone have find
a solution for this problem because it's pretty annoying for a netbook to be unable
to come back from sleep mode .
Bye.

[jawxies]

Yes, I got exactly the same probably. Very very annoying indeed.

I guess this has been a problem with ubuntu for many of the previous releases too. We better should be keeping a check with Launchpad and Ubuntuforums.

I have the problem on my Samsung N148 after upgrading it to Ubuntu 10.10
Awaiting for a fix.

No good news ? Because it's really really annoying !

To fix this you need to add "intel_idle.max_cstate=0" to the boot params.

To do that you will need to edit grub/burg. Best accomplished with grub customiser.
Download grub customiser, goto preferences, look down at kernel parameters and paste over the "quiet splash" with "intel_idle.max_cstate=0 quiet splash" Without the quotes of course.

I add this option to the grub parameters, but now Standby and Hibernate Menu entries are gone. And now?

[nroach44]

Okay, thats interesting, what version of Ubuntu are you using?
And did you use grub customizer like I said, or something else? (just curious)

When you are starting the computer, hold down the left shift button (i think) (unless you have a timer on grub).
You should now see a list that looks something like

Code: Select all

Ubuntu, with Linux 2.6.35-27-generic
Ubuntu, with Linux 2.6.35-27-generic (recovery mode)

press E while the first one is selected and then scroll down to the line that looks like

Code: Select all

Linux /boot/vmlinuz-...

and verify that after

Code: Select all

UUID=awholeloadofrandomnumbers

there is

Code: Select all

ro quiet splash intel_idle.max_csate=0

(the line may be cut out/continued below, the \ will signify this)
if it is there, but wrong, correct it and press CTRL+X
if it is there, and correct, remove the intel_idle.max_cstate=0 and press CTRL+X

Report the results here.

BTW the changes are not saved this way, it is just for the current boot.

[nroach44]

there is

Code: Select all

ro quiet splash intel_idle.max_csate=0

That should be

Code: Select all

ro intel_idle.max_cstate=0 quiet splash

if you did it the way I explained before.

But it doesn't need to be in any order.
At least I think so...

Hey guys,

i have solved this issue (and others) with an old kernel : 2.6.34

Please look at this thread, i think it's the easiest way : http://www.voria.org/forum/viewtopic.php?f=3&t=728
