Hi Everyone!

I am not professional in Linux, and I am learning it. I have Opensuse 13.2 on my laptop. I cannot hibernate or sleep. When I try to hibernate opensuse I have just blank balck screen, and the computer does not hibernate or turn off.

I also removed pm-utils. But it did not work!

I would be so grateful if you could help me with this mater!

Best Regards,

Hello,
You will need to give more information regarding your computer, if you are running Windows, the version, etc.
If sounds like you might need to install your graphics driver fglrx. Your information about the computer is important.
In addition, if you are running Windows 8 you will probably have to modify your efi file.
You will probably need to check grub, see that it is telling your computer where to save the data when you hibernate, possible modify nomodeset, etc.
Kind regards

Some quick responses:

1) Concerning hibernate - Have you given it time to write out the hibernate data to the swap file? It can take a while before the computer actually hibernates.

2) The #1 cause of not getting the computer to sleep of hibernate properly is the configuration of APM and ACPI in the BIOS setup. Also check the motherboard errata for incompatibilities regarding ACPI.
We think the motherboard/BIOS -people by now should have ironed out all these bugs. But the truth is that motherboard/BIOS bugs concerning APM and ACPI still is very common. And when the UEFI BIOS entered the scene, it all got into some kind of medieval renaissance of BIOS bugs.
First thing to check is that the computer actually shuts off power when you shutdown the computer.
If it doesn't - Then something is not setup right with APM/ACPI.

3) What are the boot configurations? Maybe you have settings like "noacpi" that prevents using sleep or hibernate? Does it at least boot with ACPI enabled in the kernel?

4) are you using raid for disks? Not all raid configurations work with sleep mode.

5) Is the "swap file" at least slightly bigger than the amount of RAM in the computer? Otherwise hibernate may fail since it cannot write out everything in RAM memory to disk. The "swap file" must be setup as a partition to be able to use it for hibernation. You will need a swap partition big enough, and it should be a simple swap partition on a non-raid disk. Also, the swap partition used for hibernate must be properly pointed out in the boot setup. At least so it is checked for hibernated contents at boot.

6) Do you have any virtualisation on the computer, like XEN/KVM/QEMU/VMWARE? this may well prevent the use of sleep mode, and sometimes it also affects the ability to hibernate.
If you are using virtualisation, then forget about sleep mode.

7) I think that what davesny means by mentioning windows is, that dual booting affects the actual boot settings, and that it might be complicated to set up proper multiboot if something like UEFI boot is used, and that there are some issues with windows clobbering things in the boot that it should not touch.
