[Bug 50031] How to get suspend-to-ram back on Edgy for laptops that actually don't go into suspend anymore

[Gabriel Ambuehl]

Ok, on my laptop (Toshiba Portege M200) the following works:

Install powersaved if you don't have it already.

Edit /etc/powersave/powersaved,

Change

UNLOAD_MODULES_BEFORE_SUSPEND2RAM=""

(possibly it's commented out, if so, uncomment it or has some modules in there 
already, if so, you might want to keep them)

to something along the lines of (you might need other modules depending on 
your hardware configuration)

UNLOAD_MODULES_BEFORE_SUSPEND2RAM="usb_storage usblp usbmouse ehci_hcd sbp2 
ohci_hcd uhci_hcd stir4200 ohci1394 ipw2200 rt2500 prism54 ath_pci r8169 
lt_modem Intel536 Intel537 ndiswrapper"


needs all be on ONE LINE.


Then try running powersave --suspend-to-ram. 

For me, that did the job.

If you're a KDE user, also get kpowersave, quit guidance-powersave and start 
knetworkmanager instead. I don't use gnome so I can't tell what 
infrastructure you need.

If you run into issues with your display, you might want to install suspend 
(especially the s2ram app) from suspend.sf.net. Just shout if you need help 
with that.
