Comment 0 for bug 269974

I just installed Ubuntu 8.04.1 with the amd64 alternate installer on a Dell Latitude D630. It's an all-Intel version, ie X3100 graphics and iwl3945 Wifi. All the latest updates have been installed.

Funny behaviour: when I close the lid, it smoothly goes into suspend, and on opening the lid comes back again (great!). However, when instead I hit Fn+F1, it takes much longer to go into suspend, then actually seems to power down the hardware: no more blinking suspend light. So it seems to call different scripts for these two cases! I checked in System -> Preferences -> Power Management, and both for "laptop lid is closed" and "suspend button is pressed" the setting is "suspend".

Further info: when I try to restart the machine after the Fn+F1 way of suspending, it cold-boots and shows grub, then refuses to mount the swap partition - saying that this contains a valid suspend image. But it doesn't use that image, and instead continues booting, only without the swap space. I can then reenable the swap later using "swapon" - this reinitialises the swap space.

It's not important to me as I can get all the functionality I need through lid-close, but I'd be happy and curious to investigate if you can tell me where to look. Thanks.

(There's also a second but probably unrelated issue - sometimes keyboard and touchpad are not detected after resuming from lid-close. This can be remedied by closing the lid again, sending the machine back into suspend, then opening it once more. Not easy to replicate though and as I said probably unrelated).
