suspend to memory does not work after upgrade

[nanotube]

Hey all
so i finally upgraded from breezy to dapper. wee.
have one problem that i have so far not been able to resolve. suspend to memory stopped working!

i have edited my /etc/default/acpi-support to uncomment ACPI_SLEEP=true (since it reverted during upgrade), rebooted, but the suspend option still does not show up in the new "quit" dialog.

also, in breezy, it was possible to set a shortcut for suspend in the keyboard shortcuts panel, but that line item is no longer present there.

also, i tried running
"sudo /etc/acpi/sleep.sh force"
and it suspended properly, but failed to wake up.

there is one other thing - i have switched from using the oss "ati" video driver to using fglrx (in the hopes that it gives better performance - and it does), that may have something to do with it, possibly? but it should not affect whether suspend option even shows up in the first place, though..

so, i would appreciate any help and suggestions in this regard.

using dell inspiron 5150, if it makes any difference.

please share your ideas with me.

update:
well, i enabled the suspend to memory to actually show up by going through the system>preferences>power management panel (on the last tab, i chose "suspend" as action for when sleep button is pressed, and it asked me if i am sure i want to enable suspend, and i said yes, and now it shows up )

but: it still does not resume properly (screen remains blank). i tried this now with both the stock "ati" driver as well as with the "fglrx" driver, and both produce the same result, resume from suspend "does stuff" but the screen remains totally blank. ctl-alt-f2 does not help, ctl-alt-backspace does not help, and ctl-alt-delete does restart the computer

so, anyone have any clues, things to try, etc? i will note that suspend worked perfectly under breezy, so it's not the hardware's fault, it's gotta be something new in one of them acpi scripts that screwing it up...

ok, so i looked around, and played around with my /etc/default/acpi-support file, and have some encouraging results.

here are the changes i made:

20c20
< MODULES_WHITELIST=""
---
> MODULES_WHITELIST="fglrx"
32c32
< # SAVE_VIDEO_PCI_STATE=true
---
> SAVE_VIDEO_PCI_STATE=true

so, after i did this, and suspended, and resumed - it resumed properly, but then froze like 30 seconds after it came up. but at least this is encouraging, because i was able to start using the system, etc.

next thing i tried (since i started suspecting network-manager as the culprit, since it failed to connect to the net between resume and the freeze, even though usually it connects pretty quick). so i disabled the wireless device (there is a kb shortcut for wifi to turn it on/off), and /then/ suspended, and then resumed, and then turned on the wireless device. and it worked, and so far no crashing.

i will have to test it some more i guess, but looks like i am making progress.

but don't let that stop you, please, if you have some ideas/suggestions, i'd appreciate them. i am kinda poking around in the dark here.

and so, i am replying to my own thread yet again.

it appears that the resume from suspend issue is still not solved. after some time i started seeing graphical artifacts on the screen (like pieces of screen becoming wrong color, or not updating, etc), and then after some more time, the comp froze, just the mouse moving, and not responding to any clicks or any keyboard commands. so i had to hard boot it.

so i am back where i started - suspend is still inoperable.

can anyone help me out here please?

ok, yet another self-reply, but this time i think with good news. i made the following changes to /etc/default/acpi-support:

23c25
< SAVE_VBE_STATE=true
---
> SAVE_VBE_STATE=false
29c32
< POST_VIDEO=true
---
> POST_VIDEO=false
35c40
< USE_DPMS=true
---
> USE_DPMS=false
42c48
< # DOUBLE_CONSOLE_SWITCH=true
---
> DOUBLE_CONSOLE_SWITCH=true

(and of course, ACPI_SLEEP=true is uncommented)

then i also made a change to /etc/acpi/wireless.sh (because i have ipw2200 wifi - not needed if you don't have it, i guess)

9c9
<           echo -n 2 > $DEVICE/device/power/state;
---
>           echo -n 3 > $DEVICE/device/power/state;

and now everything appears to work right for going into and out of suspend.

now, i am not sure which one of these did the trick, but the trick was done, and i'm happy enough for now not to go mucking around with this anymore.

I guess changing vbe_state to flase did the trick. That worked for me when I was using fglrx. But with fglrx breaking down with every other ubdate I switched back to open source Radeon. On my system the difference is just marginal and I can live with that.

These changes seem to work well with my notebook too! Thank you!

yea, i considered that, but my system really does feel snappier with fglrx. also, with oss radeon, i get
6722 frames in 5.0 seconds = 1344.386 FPS
and with fglrx i get
9137 frames in 5.0 seconds = 1827.332 FPS
a 50% difference.

but anyway, thanks for liking that launchpad page, i suppose maybe it was the vbestate thing. but i am not gonna be playing with it anymore, since it works so well for me now.

Thanks this fixed my suspend to memory issues on my dell d600.
