gutsy crash on standy or hibernate

Bug Description

Binary package hint: linux-source-2.6.22

When I try to standby the computer, or hibernate, the computer seems to begin with the standbye process, but it is staying on a black screen.
Nothing is responding, the capslock is blicking, and I have to power it off manually...

Thank you for your bug report. Could you copy here the output of uname -a ?

Thank you. I'm assigning this to the kernel team.

The similar story with Compaq nw8240.
Nor hibernate nor suspend works. Before upgrading to Gutsy hibernate works.
Now system makes screen black and I see HDD works about 2 seconds. After I can switch to a text mode (by alt-F1) but can not type in anything. I need to power off the laptop manually. After I restart a laptop system does not "resume" but fix filesystem.
I've attached zip with output of dmesg (file per hibernate and suspend), free, kern.log, lspci

Confirmed on Acer Aspire 5502WXMi. Again, worked fine on Feisty.

I have the same problem on Dell Latitude D510. On Feisty it was fine.

Confirmed on Shuttle AMD 64 barebone. All was fine before upgrade from feisty.
I tried to change the ACPI options in the bios, to no avail.

Same problem on Dell Latitude D810. Suspend to RAM (and possibly hibernate) used to work correctly under feisty.
Under gutsy, the screen goes blank, with blinking cursor, but the machine never turns off. Have to turn it off with hard shutdown (press and hold the power button).
Let me know if I can provide any more details.

I've got a similar bug but only with the -rt (realtime kernel):
Linux ubuntu-desktop 2.6.22-14-rt #1 SMP PREEMPT RT Sun Oct 14 22:53:32 GMT 2007 x86_64 GNU/Linux

The generic kernel 2.6.22-14 works just fine.

Not very hopeful, but informative.

Anyone attempted a kernel upgrade/downgrade to work around this?

I confirm this (black screen without actually powering off) with stock -rt flavor kernel on Thinkpad X61s; -generic hibernates and suspends just fine.

Confirmed on Intel D915GAV mainboard with Pentium 4 HT 3.2 Ghz processor and Nvidia 6200 video card.

This also applies to Dell Inspiron 6400 bios A17 (Intel Core 2 Duo T5600).

A laptop that cannot be suspended simply does not work for me - back to Windows, I'm afraid.

I can also confirm this issue on my desktop system with Gutsy AMD64, but only with the -rt kernel. With the generic kernel suspend to disk works just fine.

Upgrade to Hardy's kernel 2.6.24-2 fixes this problem or downgrade to Gutsy kernel 2.6.22-12. I can confirm this myself, other people should try this as well.

Also happening on HP Pavilion dv2308tx.

I can confirm on HP Pavilion dv2308tx, upgrading to Hardy's kernel 2.6.24-2 fixes problem with suspend, but hibernate still doesn't work - though it doesn't lock up the system, just blank screen, then after awhile, the screen shows the unlock screen.

To get hibernate to shutdown, I need to change HIBERNATE_MODE to platform in /etc/default/acpi-support.

Khurrum1990 (khurrum1990) wrote :

Oh yeah to those who upgraded to Hardy's kernel please make sure u upgrade ur nvidia drivers from the restricted repositories for Hardy. It should work then.

Khurrum1990 (khurrum1990) wrote :

Sorry, but I think ATI users need the latest drivers as well. I never used an ATI card with Linux so I don't know what package to install but u could always use Envy to install the latest drivers.

For nvidia add this repo in sources list:

deb hardy main restricted

sudo apt-get update

sudo apt-get install nvidia-glx-new

u can install the legacy version as required for ur card.

Hi All,

Thank you for your comments and helping to make Ubuntu better. The symptom of this particular bug, failure to Suspend or Hibernate, is specific to the hardware used. So while many of you may have the same symptom they really should be different bugs. It would be helpful if everyone were to test with a Hardy Alpha build, , and if the issue still exists, open a separate bug report for their hardware using "linux" as the package. The bug report should contain the information requested at . Additionally, it would be great if you made the titles of a new bug report contain information about your system. I apologize for any inconvenience this might cause but appreciate your cooperation.

Finally, <email address hidden>, since you are the original bug reporter. Can you comment if this issue still exists in the new Hardy Alpha release? Thanks.
