suspend to RAM doesn't work with Kubuntu 10.04 on Acer5530g

[Tommy_CZ]

Hi, i tried to suspend to RAM my Acer5530g but it hangs on after lock the screen, the screen is black but the ON LED still lights and it doesn't go to sleep.I have 2.6.32-22
With 2.6.32-21, suspend to RAM was possible, but wake-up (resume) hanged on the turned-off screen.
Thanks for any help

sometimes it does some thing as on kernel 2.6.32-21 (see above) :/

[Jeremy Foshee (jeremyfoshee)]

Hi Tommy_CZ,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I normally don't go here, to the scary bugs collection...but Suspend to Ram does not work for me either. I don't know how to get relevant logs from my system.

Anyhow, I'm on an Asus UL30jt with Kubuntu 10.04 with KDE 4.4.4 and a 2.6.34 kernel (i followed this guide: http://www.ramoonus.nl/2010/05/linux-kernel-2-6-34-installation-guide-for-ubuntu-linux-10-04/ ). I have no idea if that counts as upsream...or if our similar suspend-to-ram issues are related at all. (We're on quite different hardware it seems...but perhaps both are recent with some new software hoop or quirk that linux fails?)

[YAFU (yafu)]

Suspend to RAM fails in Kubuntu 10.04 64bit on my PC (ASUS M2A-VM HDMI, 1GB RAM). Sometimes suspended to RAM works the first time, sometimes not. Then failure is more common.
In my case, I think everything is related to RAM and Swap, and how they work. I have only 1GB of RAM. I changed the swappiness from 60 to 30 to reduce the Swap usage, and since then, Suspend-Resume problems were significantly reduced.

Hi Jeremy, please can you tell me how can I use upstream kernel? The URL you posted here is for mainstream kernel.
nakerlund: Hi, I must admit that the newer kernel was the solution for me, I suppose it is working now (2.6.32.15-5) but it is a PC of my friend, not mine. I can suggest you just to try different versions of kernels (http://kernel.ubuntu.com/~kernel-ppa/mainline/) , you know how to install it don't u?

YAFU: what is your SWAP size? Ubuntu have huge problems in hibernation, but suspend to ram is better in 10.04 i think...

[YAFU (yafu)]

@Tommy_CZ
I have 1GB of swap.
I have never used hibernation. I'm pretty sure my problem with 2.6.32-22 kernel is related to what I have mentioned before, I have not major problems since I modified the swappiness.

Anyway I'm testing the 2.6.34-020634 kernel with swappiness=60 and seems to manage better RAM and Swap usage, and till now I had no problems suspending to RAM in five attempts.

By the way, to install the mainstream Kernel, go to the folder "v2.6.34-lucid/" and download the packages in a folder "linux-headers(all)", "linux-headers(for your system architecture)" and "linux-image(for your system architecture)" (they are 3 packages). Then enter to the download folder, open terminal and run "sudo dpkg -i *.deb". At the end of installation, restart your computer and enter from the new Kernel in Grub.
If it runs worse with the new kernel, to uninstall simply search for "2.6.34" in your package manager and uninstall the three packages.

Tommy_CZ,
    The mainline kernels are the upstream vanilla kernel with a few critical configs added.

Thanks!

[Tommy_CZ (t-kijas)]

YAFU: Yeah, thanks, well.... but I thought upstream kernel :) I know howto install an mainstream kernel :)
Jeremy: Thanks, but howto install it?

[Tommy_CZ (t-kijas)]

Ok, I do not know what is the difference between upstream and mainstream kernel and noone seems to explain it to me so I will try 10.10 beta and refer.
