Suspend/resume

[mag]

My system won't suspend (under Openbox) or sleep (under KDE) and then successfully resume.

It suspends/sleeps apparently OK.

On resume the HDD starts to spin, but the screen stays blank and the CD drive starts up and and goes into and endless loop of initial 'clunks'.

No other distro that I've tried will suspend/resume successfully either on this machine (though the symptoms differ).

The machine is an e-machines E4062. About 6 years old.

1.5Gb RAM, twin Pentium D processors. ATI RC410 (Radeon Xpress 200) video card.

Any pointers as to where I might start looking to investigate further?

Thanks

Do you know if it ever did it with Windows?  It  might be a hardware problem.  Not as in failure, but as in design, it is pretty old.

It ran xp without problems on suspend or hibernate.

I agree it might well be hardware compatibility with linux though - given that it won't suspend/resume with linux mint gnome or LXDE either.

How big is your swap partition?

[mag]

It's 3.9Gig (I just let draklive installer set it's own swap size - PCLOS has the entire 120Gig HDD).

Hi mag,  I've had differing success with different kernels.  Some kernels, suspend from the menu works fine, others not so much.

I've always been able to get it to work with s2ram - it's in the repo.

Have a look at this...

http://tr.opensuse.org/S2ram

It gives some examples of switches that might help your hardware when it resumes.

If one works for you, you can create a launcher for your taskbar.

HTH,

Thanks for the info - it looks very interesting.

My novice's exploration of Linuxland has been diverted down another path at present - but I'll get back to this.

One question that immediately occurs to me - should I uninstall suspend to install s2ram?

(Edit - I think you can probably ignore that question - I see that PCLOS Openbox seems to have both installed already)

[mag]

I've /bin/bash-ed my way through all the s2ram options in the opensuse link - but sadly none have resulted in a successful resume.

I'm now using LXDE. Another change to my system - I have installed a new video card (nvidia GeForce 8400GS) to solve a problem of occasional boot failures (which it did).

The resume behaviour is now different. It now all sounds much more hopeful (no CD drive clunking), but all I get is a static cursor at the top left of the screen.

This is the same display I get briefly before the nvidia logo appears during normal boot - so I'm wondering if the break point is perhaps trying to restart the video card?

If anyone has any other suggestions on how to get suspend/resume working I'd be pleased to hear them.

Thanks

Just in case it's any use to anyone else having this problem, the solution for my machine seems to be to use 'noapic' in kernel boot options.

What kernel are you using?

[mag]

I had the problem using 2.6.38.8-pclos3.bfs.

I tried the fix out with a PCLOS LXDE LiveCD running the same kernel.

Without noapic it won't resume from suspension. With noapic it will.

This machine actually has xubun2 12.04LTS installed now -so I can't try it out on a PCLOS installed OS at present, or on the more recent kernels - I'll get round to that sometime in future.

[mag]

PCLOS KDE 4.8.3  (3.2.18 kernel) now installed on HDD, and suspend/resume is working with noapic in boot line.

Congratulations! I'm glad you found a solution.

Thanks - and it's only taken me 9 months!
