System can't sleep or hibernation

English Install/Boot/Login
#1

Hi,

Recently, I found my system can’t sleep or hibernation.
Whatever I click “sleep(suspend to memory)” or "hibernation(suspend to disk),
the system just lock the screen, don’t sleep really.

I don’t know how to check it, so hope I can get help from here! Thanks!

My system is openSUSE 11.3 x86_64, KDE 4.5.3 .

Disable splash screen, enter hibernation from command line (pm-hibernate).
If this succeeds, the problem is your machine is not whitelisted.

If it locks, try the same in runlevel 3. If this succeeds, the problem is
the video driver.

Hi, I tried the first method, it’s ok.

How can I resolve this problem?
What’s meaning the whitelisted?

Thanks!

That your machine is not known to be able to hibernate, so the desktop will
not do it. Ah! I forgot that sometimes the system thinks that the user is
not permitted to hibernate.

There is a wiki page in opensuse that talks about this, and gives the exact
command to know if your machine is known.

My machine also does not hibernate with a click - I always use the command
line. I haven’t bothered to report it. CLI is faster.

Okay, thank you very much!

I will use CLI too.

FYI hibernate uses the swap space to store the image. So be sure swap is at least as large as you memory 1.5X would be best.

Yes, thanks for your reminding!
