h2sammo,
Try the tuxonice kernel
Suspend to disk and suspend to RAM are really intended for laptops but there is no reason why you sould not try it on a desktop too.

| You can also use s2disk from sys-power/suspend in a stock kernel if you enable the hibernation options. |

if i use stock kernel and sys-power/suspend do i have to set a hibernation partition in the kernel (i saw an option for it).
what should i put there? /dev/sdax or the swap partition? does it matter?
do i have to edit grub even if i use sys-power/suspend and stock kernel or suspend will make those changes for me? |

You do not need to set one, but it is easier to set it in the kernel configuration than to configure it at runtime.

Specify the swap partition.

Grub does not need to be modified at all to work with s2disk based suspend, but you do need to have the resume kernel know to resume, either via an initramfs or a command line entry. I use an initramfs since I hibernate to encrypted swap. |

i went ahead with the gentoo preferred tuxonice. i followed instructions but on reboot, tuxonice loads with an error and trying the hibernate command fails with an error as well, any ideas?
| Code: |
localhost bobby # dmesg | grep TuxOnIce
[ 1.204514] TuxOnIce 3.2-rc2 (http://tuxonice.net)
[ 1.209782] TuxOnIce: No matching enabled allocator found. Resuming disabled.
localhost bobby # hibernate
/usr/share/hibernate/scriptlets.d/tuxonice: line 525: echo: write error: Device or resource busy |
one thing different from the setup was that i cold not find the following in my kernel so i did not enable it:
| Quote: | Processor type and features --->
[*] Support for suspend on SMP and hot-pluggable CPUs
|
also, hibernate command is not recognized from my user, only from root.
thx |

h2sammo,
Please post your kernel .config file and grub.conf
If you have an initrd - how was it made?

emerge pm-utils
/usr/sbin/pm-suspend for suspend-to-ram
/usr/sbin/pm-hibernate for hibernate
Make sure you have the support enabled in your kernel for whichever suspend method you want to use. Suspend works quite well in current kernels; TuxOnIce shouldn't be necessary these days. |

w/ a str8 vanilla kernel | Code: | | sync; echo mem > /sys/power/state |
suspends and | Code: | | sync; echo disk > /sys/power/state |

h2sammo,
This truncated part of grub.conf
should say resume=swap:/dev/<your_swap>
You need to use the command | Code: | | nano -w /boot/grub/grub.conf |
to avoid lines being truncated.
Your kernel looks ok.

thank you i have fixed that:
| Code: | title Gentoo Linux 2.6.36-tuxonice-r3
root (hd0,0)
kernel /boot/2.6.36-tuxonice-r3 video=uvesafb:ywrap,mtrr:3,1280x1024-32@70 root=/dev/sda3 resume=swap:/dev/sda2 |
based on
| Code: |
Device Boot Start End Blocks Id System
/dev/sda1 63 80324 40131 83 Linux
/dev/sda2 80325 16868249 8393962+ 82 Linux swap / Solaris
/dev/sda3 16868250 217279124 100205437+ 83 Linux
/dev/sda4 * 217279125 390716864 86718870 7 HPFS/NTFS |
but it still complains:
| Code: | localhost bobby # hibernate
/usr/share/hibernate/scriptlets.d/tuxonice: line 525: echo: write error: Device or resource busy |
any ideas? |

Can I do this without being root?
I can't seem to execute this command even with sudo.
Only root(su) seemed to work |

| Please do not resurrect retired threads for off-topic questions. You must be privileged to suspend or hibernate the machine. You did not explain how you failed, but you most likely made the standard mistake of most sudo users. Redirections are processed by the unprivileged shell, before sudo runs. |

What does that mean?
and is it bad to resurrect retired threads? |

ShanaXXII, though it was great that you searched for a similar problem, but your problem deserves a new posting "create a new thread" because it is of a different aspect than of the original thread creator, and can be confusing to people subscribed to the thread.
Anyway, to clarify the redirection problem Hu hinted at, these two methods should work for you to write while in a regular user shell as /sys/power/state requires root to be written to:
sync; sudo sh -c 'echo mem > /sys/power/state'
or
sync; echo mem | sudo tee /sys/power/state
