Standby Problem

[TNTman]

I have had running a MSI board with Intel Core 2 Duo,2X 2gb DDR2 memory and an Nvidea 9500 graphics card.
With PCLinux KDE. Kernel 2.6.38.8-pclos1.pae.bfs.
All working perfectly.
That I have stripped out and replaced with :-

PCLinux KDE Kernel 2.6.38.8-pclos3.pae.bfs.
‎Intel Core  i5-2500K CPU @ 3.30GHz.
ASRock H61M/U3S3 mainboard.
4gb Patriot memory (shared).

The new rig booted first time and is running well (Thank you PCLinux team amazing).
The only issue I am having is with Sleep mode, the machine will go to sleep mode and things appear as normal.
But, on trying to recover the fans run, lights come on but the machines locks up.
No key combinations work and even the reset button has no response. The only way out is to power off.
Standby mode just re-boots.

Is anyone able offer advice?
Thanks in advance TNT.

Sorry no answer, just:
my system has been working well - then I decided to put in a 2TB Seagate HD. I installed my setup and now get the same problem with Sleep mode.
I can put back my older HD and Sleep mode works fine.

How big is your SWAP partition?

Hi TNTman,  I've had hit and miss luck with s3 sleep using different kernels.  Some work well with the sleep launcher in the menu, others end up with the symptoms you describe.

Install s2ram and read this...

Mentioned are some command switches that can help with the awakening process.

I then made a launcher with my appropriate command "s2ram -f -s" and it lives in my panel.

HTH,

Dave

Hi rubentje1991,
                     thank you for your interest. Swap size 3.9gb.

Have just tried a fresh install using USB Stick with the latest KDE 2012 ISO.
Still hangs on SLEEP.

Thanks to Rocforfun, will do some reading and then trials.

Thanks to Rocforfun,
have done a little reading, quickly realize that this is well beyond my abilities.
Thanks for the reply,

With 4GB RAM you need a swap bigger than 4GB, so 3.9 isn't enough. You probably should have 6GB.

However, unless you were using RAM very heavily, it's probably not the problem.

Hi KJP,
        now have 8gb of ram, and have upped the swap to 9.8gb.
The problem remains, computer hangs on recovery from sleep.
Thanks for reply,

Mmmh... upgrading RAM wasn't necessary to enable sleep mode... - and I always do SWAP size = 2 RAM size (but that probably is deprecated  )
=> possibly another cause for this, ....

Reading through your first post again...
=> you get your pc out of sleep, but it doesn't react as expected and even the reset button doesn't react? => maybe some setting in the BIOS?

I remember having sleep issues with my laptop which I remedied with changing power managers.
Also, IIRC the power manager controls some aspects of sleep (S2) which could be tweaked.
My experience was from early KDE4 so may not apply here.

Thanks ruben,
        just to recap' computer goes to S3 sleep OK, power light blinks and monitor goes to standby.
Press any key to wake machine OK. Power light comes on steady, fans start, hard drive light flickering (suggests activity), monitor stays on standby (black screen) or says no signal. Reset button now not responding. Have to power off machine on main switch.
    This is now a dual boot computer, have installed XP and that goes to standby and recovers OK. Perhaps suggesting that the BIOS settings are OK.
    ASRock main board has the new UEFI bios that I have little knowledge of, so I may well be using incorrect settings.
Thanks to all who have helped, TNT.

UEFI is awkward with Linux. It isn't BIOS though it fits in the same place, but it's much more powerful and much fussier. This could well be a setting or a compatibility problem, or it might be kernel-related.

That it works with Windows isn't really much of a confirmation of anything, as UEFI is so different with different OSes. You might be able to find a setting that works with both, or maybe it'll work better when we get newer kernels. It's anyone's guess, really.

Sorry, can't help any more as have no experience of UEFI.
