[HowTo]: Fix suspend and hibernate on laptops

[crazedgremlin]

thanks - very nice - I've been having problems with suspending on a dell inspiron e1505n (yes, the one that _came_ with ubuntu).

It works fine, except that when I resume from suspend I see my session there for 2 or 3 seconds and then it goes back to suspend. the second time I try to wake it up it will work.

it goes:
-Ok, I'm using the computer
-I hit stand-by key
-the computer goes to sleep
-I hit the power button to wake it up
-the screen turns on - I can see the previous session
-BLOOP! it's gone- the computer went to sleep again
-I hit the power button to wake up
-it works!

not really important, but can anyone shed any light on this?

[crazedgremlin]

ok when I hit fn+standby, I encounter the previously mentioned problem.
when I do K menu -> logout -> suspend, it works the way it should.

I guess I'll just use the K menu from now on.

Will I have to redo this when it's time to upgrade to Gutsy Gibbon?
Triple post ftw!

[crazedgremlin]

ok I fixed my problem! yay!
I did

sudo -i
cp /etc/acpi/sleep.sh /etc/acpi/sleep.sh.bak

apparently it ran through two different sleep scripts when I hit the suspend key

If you have errors there are a bunch of settings to mess around with:

man s2ram:

OPTIONS
       -h, --help
              Short help text.

       -n, --test
              test if the machine is in the database. returns 0 if  known  and
              supported

       -i, --identify
              prints a string that identifies the machine.

       -f, --force
              force  suspending,  even on unknown machines.  the following op‐
              tions are only available with --force.

       -s, --vbe_save
              save VBE state before suspending and restore after resume.

       -p, --vbe_post
              VBE POST the graphics card after resume

       -r, --radeontool
              turn off the backlight on radeons before suspending.

       -a, --acpi_sleep
              set  the  acpi_sleep  parameter  before   suspend.    1=s3_bios,
              2=s3_mode, 3=both

       -v, --pci_save
              Save the PCI config space of the VGA card before suspend and re‐
              store it after resume.

Also, it is recommended to use s2both instead of s2ram in case the system loses power.

       s2both will do precisly the same as s2disk except that it will not pow‐
       er off the system, but will suspend it to ram (put  the  system  in  S3
       mode). This has the advantage that resume will be faster, with the dis‐
       advantage that you still use batteries. If they batteries  do  deplete,
       you  still  have  the system state saved to disk and can resume without
       data loss.

       You will need to set up an initramfs which calls the resume program for
       this  to  work. If you use an debian kernel package which was made with
       the --initrd option and you use mkinitramfs-tools, this package  should
       include the necessary parts on your initramfs.

That doesn't make sense. Did you move (mv) it instead of copy (cp)? Or did you enter some code in the original file after copying it, or make it non-executable? Otherwise, the old script ought to still run.

I have the same laptop and same problem with the "start" button bringing it back but only to go back to suspend again. But, the laptop lid switch works better .. just close and reopen the lid and it will resume from suspend.

haha you're right,
I did mv instead of cp

I really need to proofread before I post

OK, so now I have a working suspend / resume and hibernate / resume. Suspend / resume worked before, but hibernate never did. I have a dell e1505 with nvidia card.

But, still there is a problem when I use compiz/compiz-fusion/beryl. After one or two successful suspend / resume cycles, the computer locks up and I have to power off and reboot. This happened before and even now with uswsusp. I know about unchecking "sync to vblank" with compiz, but still have the problem. I also know that if I disable compiz before suspend / hibernate, resume will work. Of course, turning off compiz causes all open windows to bunch together, so it makes a lot of work after resuming. Anyone have a solution to this?

My computer will lock up like that too, whenever the display goes to sleep for too long without expliciting suspending or hibernating the system. If I have Compiz or Beryl installed (or maybe even if I'm just running Xgl, who knows?), then my computer will freeze up much more often it seems. And when my computer does this, I've learned to make sure there is no external hard drive mounted or else.

What is the "sync to vblank" option?

Anyways, I actually came to this thread because it solved my suspend/hibernate problems, but I just now noticed that my computer still locks up when the display goes to sleep and I don't know how to get it to resume.

[Paul S]

What is the "sync to vblank" option?

I think it's discussed on the beryl troubleshooting page:

http://wiki.beryl-project.org/wiki/T...hooting_nVidia

It applies only to nvidia video cards.
