hi, it seems like suspend to ram works ok.
hibernate still has problems. after resume, the machine sometimes dies after 
some minutes.

Most of the time suspend to RAM works for me with Intrepid but randomly
the keyboard and touchpad will not work.

The network and X come back to life and the power button works but
keyboard and touchpad do not. Only resolve is to hard power off.

Did not quite work for me in Intrepid Alpha 5 with all the updates. The
result is the same as in previous two Ubuntu releases. The system does
not wake up from suspend to ram on it's own. (Unless I don't hold down a
(any) key on the keyboard. Then it wakes up in ~10-15 seconds).

[Leann Ogasawara]

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release.  As a result, the kernel team would
appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.
There are one of two ways you should be able to test:

1)  If you are comfortable installing packages on your own, the linux-
image-2.6.27-* package is currently available for you to install and
test.

--or--

2)  The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer
2.6.27 Ubuntu kernel.  Alpha5 is set to be released Thursday Sept 4.
Please watch http://www.ubuntu.com/testing for Alpha5 to be announced.
You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the
bug reported here or if the issue remains.  More importantly, please
open a new bug report for each new bug/regression introduced by the
2.6.27 kernel and tag the bug report with 'linux-2.6.27'.  Also, please
specifically note if the issue does or does not appear in the 2.6.26
kernel.  Thanks again, we really appreicate your help and feedback.

[randallw]

This problem (keyboard failure after resume) is still present for me in Hardy 
but appears to be fixed in Intrepid alpha 4 (for me with the live CD, at least).

In Hardy, my suggested fix above also doesn't work because the suspend/resume 
scripts look to be generated automatically. I found a (hack) workaround by 
adding the two magic lines to
/usr/lib/hal/scripts/linux/hal-system-power-suspend-linux
however this script tends to be overwritten when some packages get updated so I 
wouldn't call it a permanent fix.

[Bug 81767] Re: Suspend to RAM does not work well on HP notebook nx7400 in feisty

[randallw]

Thank you so much for posting this workaround! I have been annoyed by
this problem for several ubuntu releases now, each time hoping the
problem would be magically fixed. Anyway, in case others are having this
problem and want to automate this workaround, I did the following. (This
is for Ubuntu gutsy.)

For reference, ACPI resume appears to execute the script
/etc/acpi/resume.sh when it is resuming from suspend. This script just
executes all the scripts in /etc/acpi/resume.d/ .

As root, create a file called: /etc/acpi/resume.d/99-fix_keyboard_bug.sh
e.g.: sudo gedit /etc/acpi/resume.d/99-fix_keyboard_bug.sh
(You can call it something different if you like, but it would be wise to have 
it start with "99" so that it is the last script to be executed during resume.)
Put the following text in the file:
#!/bin/sh
# fix occasional keyboard failure after resume from suspend-to-ram.
# See ubuntu bug 81767

echo -n "i8042" > /sys/bus/platform/drivers/i8042/unbind
echo -n "i8042" > /sys/bus/platform/drivers/i8042/bind
echo `date` > /tmp/resumed.txt


(The last line is optional. I just did it to verify the script was being run on 
resume.)

Now make sure the file is executable:
sudo chmod 755 /etc/acpi/resume.d/99-fix_keyboard_bug.sh

That's it. Happy suspending.

[Bug 81767] Re: Suspend to RAM does not work well on HP notebook nx7400 in feisty

[Jan Skowron]

Solution:

  sudo sh -c 'echo -n "i8042" > /sys/bus/platform/drivers/i8042/unbind'
  sudo sh -c 'echo -n "i8042" > /sys/bus/platform/drivers/i8042/bind'

Problem with keyboard not working after resume from suspend is in driver i8042. 
Until it will be fixed I advise to use this workaroud.
Other solution is to complile i8042 as module (and maybe psmouse) and unload it 
before suspend, that load it after resume.

I have put two above lines into my Power Manager configuration 
(/etc/pm/hooks/). If you are using diferent suspend script put it there.
I have laptop HP nx7400 with Fedora Core 6, as I can see this problem is common 
through all Linux distibutions and all manufacturers. On hundreds of forums 
there are questions like: "What to do if my keyboard and touchpad doesnt wake 
up after resume from suspend or thaw after hibernate" or topics like "no 
keyboard after suspend" and "keyboard problem after resume from hibernation". I 
think it is imperativie to solve this problem once and for all.

Problem solved but only temporarlly!
Solution from: 
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/23497/comments/17

PS. sometimes after resume scroll on touchpad doest work, going to text
console (Alt+F1) and back (Alt+F7) often helps.

There is also a method for fixing the keyboard problem without having to 
compile the kernel.
See Bug #23497 
(https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/23497) for details
This works for my hp nx7400 (EY508ES, T2250)

[John Brown Jr.]

Feisty Beta almost works - it manages to wake up from suspend2ram just
fine, only the display stays off, as others have noted. It can be fixed,
though (at least it works for my nx7400 flavor).

There were 2 steps to enable display to resume:
1) I compiled i8042 as module, configured /etc/default/acpi-support to unload 
psmouse & i8042 before suspend. 

2) It's also necessary to set "SAVE_VIDEO_PCI_STATE=true" in
/etc/default/acpi-support.

Now, there is only one problem left - DPMS sometimes does not work, that
is, display backlight stays on even when the display is supposedly
turned off by gnome power utilities (screensaver, etc). I have yet to
figure out how to solve this last problem.

[Andrei Moldovan]

Hello,

The brightness problem occurs even if the driver is compiled as a
module. Any keyboard or mouse activity doesn't turn it back on. Only the
brightness keys do. So, I'm guessing that that brightness problem is
related to some weird power management feature.

I wouldn't mind the brightness problem as long as I could suspend/resume
my laptop.

[JT]

When you compiled the kernel yourself with i8042 as a module, did the
brightness issue still occur? What I am wondering is whether the
brightness is down because of a power management setting, but never
comes back up because there is no event from keyboard or mouse to tell
it to turn back on. If you don't have the brightness problem when i8042
is a module, then clearly it is just the module that is required. Sorry
if I'm being pedantic or thick, just want to be sure we know all the
facts.

Hello,

About the screen. It doesn't seem to be turned off. I can see everything
that happens as the laptop resumes. It's just that the brightness is
turned all the way down (lower than possible by using the brightness
keys). I can even see the messages as I shut it down by pressing the
power button.

If the driver would be compiled as a module it would be great. This is
the last thing I have to get to work on my laptop.

[Bug 81767] Re: Suspend to RAM does not work well on HP notebook nx7400 in feisty

[JT]

Same for me. It seems clear that i8042 as a module is the solution and 
unloading/reloading this and psmouse on suspend/resume is necessary. This 
clearly needs changing in the releases though.
The question now I believe is whether the screen is turned off and you have to 
press the brightness buttons to get it back on after resume. I do not have this 
symptom, but others have. But is it only because the screen has been turned off 
by screensaver/power management? Plugging in a usb keyboard and mouse to resume 
without needing the built in keyboard and touchpad will test this.

Hello,

The new kernel (2.6.20-12) is still compiled with the i8042 driver
built-in. Resume works, but the keyboard is inactive. Same problem as
before.

I've tried compiling the kernel myself with the driver as a module and
suspend/resume works, but I've had trouble compiling the restricted
modules (for ipw3945 wifi card).

I too have a HP nx7400 laptop and suspend to RAM/Disk does not work at
all.

My model is EY252ET#ABU

1833MHx
Processor Stepping 8
Cache Size (L1/L2) 64/2048 Kb
Memory Size 1024 Mb

I am running fiesty with kernel 2.6.20-11-generic

My suspend (to RAM) symptoms are exactly the same as those already
described.

When I suspend to disk (hibernate) the laptop is locked and I have to
enter my password to get back into the system (as if my password
protected screen saver activated).  I then get a "speech bubble" message
stating that 'HAL failed to hibernate'.

Hello,

As stated in the duplicate bug, the problem is the i8042 keyboard driver
that is built into the kernel. If the driver is compiled as a module and
removed before suspend along with the psmouse module, suspend works.

The problem that appears now is that the screen is turned off and you
have to press the brightness buttons to get it back on.

I'll get back with the logs soon.

[Bug 81767] Re: Suspend to RAM does not work well on HP notebook nx7400 in feisty

[JT]

I have the same problem on the same model notebook
However I can clarify further what is happening. I am typing this on my usb 
keyboard after a resume from suspend to RAM. I also use a usb mouse most of the 
time. The problem is that whilst everthing else seems to wake up fine, neither 
the internal keyboard or touchpad work. But usb devices do! Hence the system 
appears to be dead because there is no input available.

Here is the info you requested plus some more suggested on the ACPI
page. Also the "KernelSuspendDebugging" page doesn't exist!

uname -a :
Linux tygra 2.6.20-10-generic #2 SMP Mon Mar 12 00:02:49 UTC 2007 i686 GNU/Linux

[Cristian Aravena Romero]

Thanks for taking the time to report this bug. Unfortunately we can't
fix it, because your description didn't include enough information.

Please include the following additional information, if you have not already 
done so (please pay attention to lspci's additional options), as required by 
the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. 
It should be one, long line of text which includes the exact kernel version 
you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" and attach the resulting file 
"dmesg.log" to this bug report.
3. Please run the command "lspci -vvnn > lspci-vvnn.log" and attach the 
resulting file "lspci-vvnn.log" to this bug report.

For your reference, the full description of procedures for kernel-
related bug reports is available here:
 Thanks!
