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. -- [regression] Suspend [to-RAM and to-disk] is broken in 2.6.15-25.43 https://launchpad.net/bugs/50031 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
