system does not hibernate

[Mikel Artaso]

Binary package hint: evince

When I try to hibernate the system, just appears a blank screen with the cursor blinking and it remains that way.

ProblemType: Bug

Same problem here; nothing more than the blinking cursor. Changing to another terminal via ctrl+alt+F1 first brings up the usual login. Then everything freezes, even before being able to enter the first letter.

Not sure whether evince is responsible for this. Rather not, since same thing is happening after a fresh start of Gnome, without additional starting of programs.

Hibernation has been working perfectly well in 10.04, until I chose to upgrade via "update-manager -d" just recently.

Would like to give more help, but I don't know how.

OK, I have to correct myself. If you do a fresh start into 10.10, then start one instance of evince (might be every other program), then hibernate: everything works as supposed.

Hibernation stops working if you start more programs, like firefox+ooo+gimp and some other memory hungry ones.

In /var/log/syslog, I found something that may either be connected and helpful or not. I will post the snippet here and the other files as attachment in the next comment (launchpad responds with error 414 (url to long), when i try to attach to this comment).

Hi Mikel,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

i tried the mainline kernel 2.6.36-020636rc7-generic and hibernate works again!

[Benjamin Xiao (ben-r-xiao)]

I am getting this error as well in Kubuntu 10.10. It even happens without launching any programs. I basically load KDE, try to hibernate and it freezes with a blinking "_" cursor.

[Giorgos Kylafas (gekylafas)]

I experience the same problem in an HP Compaq nc6120. As a workaround, I use the kernel from 10.04, i.e. linux-image-2.6.32-25-generic, which hibernates and suspends successfully.

[Zed Freejack (zed-freejack)]

The problem was reproducible on a Dell Studio XPS 1340 with an nVidia chipset running Kubuntu 10.10 and this kernel: 2.6.35-22-generic #35-Ubuntu SMP

After updating to "2.6.35-23-generic #40-Ubuntu" both, suspend to RAM and suspend to disk work properly.

[Benjamin Xiao (ben-r-xiao)]

I can confirm that hibernation works with 2.6.35-23. It surprised me yesterday when I accidentally hit the hibernate button :P

[Giorgos Kylafas (gekylafas)]

I too confirm that hibernation/suspend work with 2.6.35-23.
