T61 hibernate/F12 in Ubuntu

[Paul Unger]

I'm running Ubuntu 7.10 as part of a dual-boot scheme (w/ XP). Last night I pressed Fn+F12 to hibernate. This morning I pressed the power button, selected Ubuntu 7.10 from the GRUB list, saw the splash screen w/ the orange progress bar, and then things went whacky . . . The progress bar didn't come off the left edge, a white bar cut the screen in half, then I got green "bar-code" across the top of the screen, then the suspend/hibernate moon LED started flashing, then it shut down. This took about 4 minutes. I tried again, this time selecting Ubuntu 7.10 (Restore [I think that's what it was . . . Re-something]), which showed all the text of things being started and checked, and it ended with a command prompt. I'm still at a loss w/ commands, so I hit ctrl+alt+del, just b/c that's what came naturally! This time I selected the 'normal' Ubuntu at GRUB and I'm typing this from the session that started--everything is normal as far as I can tell. So, does hibernate not work in Ubuntu? Should I stay away from the F12 button? Or is there some 'tweaking' left to do?

Hibernate and sleep/suspend are still iffy on all Linux distros.. It's just hit and miss..

I have Suse 10.3 and Ubuntu 7.10 on my Acer..Sleep and hibernate work perfect with Ubuntu, neither work for Suse..

Also have Ubuntu 7.10 on my 600x, the sleep option isn't even available.. But hibernate does work..

With some hardware it will work, with most it won't..

Keep tweaking..

On my machine with Kubuntu 7.10, hibernate has the same problem that you describe in the first post. But if I use the older 2.6.20-xx kernel instead of the default 2.6.22-xx then it works perfectly.
