Alright, assuming this issue is no longer relevant for pm-utils; reopen
(and explain further) if there's remaining work needed.

[Bug 23497] Re: i8042 unbind required for keyboard/mouse to be useable following suspend/resume & hibernate/resume cycle

[James M. Ward]

I have Lucid on a HP Pavilion DV7-1245dx, and although I needed to add
the flag "i8042.reset" to the kernel options in Jaunty, I no longer need
this flag in Lucid.  Suspend/Resume works fine for me under most
circumstances related to this bug.

I sometimes have problems during resume but I think it's only happened
when I forgot to run "fusermount" on an sshfs drive mount to un-mount it
before suspend. I just haven't gotten around to writing the
suspend/resume scripts which check for and unmount automatically.

Many thanks to whoever resolved this issue!

Suspend/resume development and testing was a key delivery goal of
Jaunty.  If you have an issue that is similar to that reported here,
please test with current Jaunty and then file a new bug with the
hardware details appropriate to your system.  Include in your report the
details as outlined in
https://wiki.ubuntu.com/KernelTeam/SuspendResumeTesting. In particular,
run the tests and report the results.

After resume the keyboard and touchpad on my laptop, HP Pavilion dv5, running 
Ubuntu Jaunty were not working. Even though if I connect the USB mouse and 
keyboard they were working. 
Adding "i8042.reset" flag to the menu.lst helped me to fix the problem.

This bug has been plaguing me since August when I bought my HP Pavilion
dv5.  The i8042.reset flag in menu.lst fixed it for me.  Thanks,
jmw86069!  BTW, I'm in the Jaunty development branch.  I recall seeing
that Jaunty was supposed to fix suspend issues -- hope this gets cleared
up before Jaunty is released.

[jmw86069]

Not too sure what resolutions people have come to, but I have an HP
dv1245dx laptop with an ATI Radeon 3200 HD integrated. I could
hibernate/resume fine, but suspend/resume resulted in non-functioning
keyboard and touchpad. The fixes above didn't work for me -- however
manually typing in the unbind/bind commands did work if I did it twice.
(Inconsistently.)

However, I stumbled upon wisdom from this thread which did solve the problem 
for me, without creating a script in /etc/acpi/resume.d/*.sh:
http://ubuntuforums.org/archive/index.php/t-1038898.html

Basically you add "i8042.reset" to the /boot/grub/menu.lst line which loads the 
kernel. I described what I did specifically in my post here:
http://ubuntuforums.org/showpost.php?p=6653249&postcount=15

I wondered if this fix may seem more "global" and may resolve the issue
for those people here, including the ones about the opposite effect
happening?

For further info, I'm using fglrx (8.12 ATI drivers) and have disabled
composite and AIGLX in my xorg.conf file.

suggest that this is not a bug in acpi-support, but maybe in gnome-

Also notice that:
- the bug always happens when resuming from suspend
- someone reported that suspending and resuming again would fix the problem: 
this is not my case. It even happened to me at least one time that after 
suspending and resuming again Jeff Abbott's fix didn't work no more, but after 
suspending and resuming again it did.

[Pietro Battiston]

I have almost the same problem with an HP tx2510: after suspend,
keyboard and touchpad don't work; if I plug in USB keyboard and mouse,
the system is absolutely usable.

If I give unbind and then bind i8042 as written by Jeff Abbott, the
embedded keyboard comes again to life, but the touchpad still stays
unresponsive. My touchpad has a small button which should enable/disable
it, and usually when using it it changes color, but in this case it is
stuck too.

I'm using an up-do-date 64 bit Intrepid, so kernel is 2.6.27-4.

I don't have this problem with hibernation (which often doesn't work,
but it's a separated issue).

[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.

More info for the last post: if I call pm-suspend directly and close and
open the lid, then it all works fine. Keyboard is activated on resume.
So it appears that gnome-power-manager is doing something to break the
keyboard. When I had Fedora Core 9 running, Gnome had the same problem,
but KDE was okay.

Still occurs in Hardy release 8.04 on a Dell Latitude D830. The
bind/unbind fix doesn't work for me: no such device when I try to write

suspend to disk the laptop keyboard doesn't work but an external USB
keyboard does. xev reports no keyboard events. Requires a reboot to
regain keyboard.

[jpiesing]

I had this bug on Gutsy (Dell Latitude D420) and worked around it by Fn+Esc 
(=standby) and then resume again.
It was relatively infrequent.

It's more common in Hardy so I tried the binding / unbinding scripts described 
above.
These didn't fix the problem and completely broke the standby / resume 
work-around. On a resume, the latptop would immediately suspend again. On a 
second resume, it would resume as far as a black screen with a cursor and then 
stop.
Pulling out the battery is easier than testing with another computer to see if 
the network was running.

I have now removed the bind/unbind scripts.

@nanog: How long should the interval be to trigger this bug? I suspended my HP 
nx6310 for ~15 minutes and after resume I had no problems with keyboard. 
I could reproduce this bug on Feisty and Gutsy, but I haven't reproduced it on 
Hardy  yet.

I have this when I suspend/resume in few times, ~1min for example and
sometimes later.
This bug doesn't appear all the time.

[Bug 23497] Re: i8042 unbind required for keyboard/mouse to be useable following suspend/resume & hibernate/resume cycle

[marauder13]

Could it be possible to add the binding/unbinding scripts to the
/etc/apm/suspend.d and resume.d instead of /etc/acpi/suspend.d and
resume.d ? I seems they are using /etc/apm folders in Hardy. I
downgraded to Gutsy so I cannot test it now.

sudo nano /etc/apm/suspend.d/20-i8042-input.sh
#!/bin/sh
# Unbind the AT keyboard interface.
if [ -f /sys/bus/platform/drivers/i8042/unbind ]; then
echo -n "i8042" > /sys/bus/platform/drivers/i8042/unbind
fi
(save ctrl-x)

sudo nano /etc/apm/resume.d/39-i8042-input.sh
#!/bin/sh
# Rebind the AT keyboard interface.
if [ -f /sys/bus/platform/drivers/i8042/bind ]; then
echo -n "i8042" > /sys/bus/platform/drivers/i8042/bind
fi
(save ctrl-x)
sudo chmod +x /etc/apm/suspend.d/20-i8042-input.sh

[nanog]

This bug is still active in Hardy and is now a regression from Gutsy
(e.g. it happens reproducibly whereas in Gutsy it was very infrequent).

I can regain keyboard and trackpad function by activating the power
button and going through a suspend-unsuspend cycle. A short suspend
interval never triggers the bug while a long suspend interval always
triggers the bug.

[Leann Ogasawara]

Hi everyone,

Thanks for testing the Hardy Alpha release.  However, please note that
the symptom of this particular bug 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 who still is
experiencing issues could test with the latest Hardy Alpha build,
http://www.ubuntu.com/testing/ .  You should be able to test using the
LiveCD, but please note you can only test Suspend from the LiveCD, not
Hibernate.  If the issue still exists, please open a separate bug report
for your hardware using "linux" as the package name.  The bug report
should contain the information requested at
http://wiki.ubuntu.com/KernelTeamBugPolicies .  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.

Also please note that we will keep this report open against the actively
developed kernel bug will close this against 2.6.20 and 2.6.22.  Thanks.

Thanks!

I've seen the same symptoms on a Dell D420 - on both dapper and gutsy.
dmesg | grep 8042 reports the following
serio: i8042 KBD port at 0x60,x064 irq 1
serio: i8042 AUX port at 0x60,0x64 irq 12

On dapper it happened perhaps 1 suspend in 20. On gutsy, it's just
happened for the first time. There's no obvious error messages
mentioning this in Xorg.0.log.

I've seen this bug on a Dell Inspiron 6400 (preloaded with feisty, and upgraded

It's not my laptop so I don't know if I'll be able to test patches.

[a.sweets]

I've got a Dell 1420n that came preloaded with Feisty.  I had the
problem in the last distro and am still noting it in Gutsy.

I'd like to play around with some of the above suggested patches, but as
they're for older distros and one has caused major crashes for James...I
guess I'll try them and report on where they leave me.

I've got my laptop set to suspend when the lid is closed so all I've
done so far when the problem has occurred is to close the laptop and let
it suspend and then wake it up again.  The keyboard and mouse usually
work again after that.

The acpi-support package consists of scripts, so you can just use the
i386 package. Do "cd /tmp; wget http://launchpadlibrarian.net/6787623
/acpi-support_0.91build2_i386.deb", followed by "ar xf acpi-
support_0.91build2_i386.deb" and "sudo tar xzf data.tar.gz". Finally do
"sudo cp etc/acpi/resume.d/80-i8042-input.sh /etc/acpi/resume.d" and
"sudo cp etc/acpi/suspend.d/20-i8042-input.sh /etc/acpi/suspend.d" and
you're all done.

[Denis Treskunov]

On a Dell Inspiron e1705 running Feisty, suspend/resume worked fine
until this one time. The touchpad and keyboard were unresponsive after
resuming. I plugged in a USB keyboard to diagnose the problem.

Doing the i8042 unbind before suspend and bind after resume did not fix
the problem. I got the touchpad back (scrolling works fine), but every
time I press a key on the laptop keyboard, I get the following messages
in my kernel log:

atkbd.c: Unknown key pressed (raw set 2, code 0x101 on isa0060/serio0).
atkbd.c: Use 'setkeycodes 01 ' to make it known.

So the keyboard is still on the fritz after doing the unbind/rebind.

Check out my little suggestion here:

(second post down)

This works for suspend to ram - and resume - but not suspend to disk.
I haven't cracked suspend to disk yet as I cannot get it to hibernate at all 
let alone resume!

[James Valentine]

I'm using a Clevo M121W laptop which is displaying these symptoms. The
keyboard and mouse can be reclaimed using ssh from another host with the
commands in https://bugs.launchpad.net/ubuntu/+source/linux-
source-2.6.20/+bug/23497/comments/17 , but the patched version of acpi-
support from Scott doesn't work for me and causes an uncontrolled
switch-off crash on resume. Because of the version numbers, it is also a
downgrade from the feisty final acpi-support version of 0.95, which
causes installation problems.

Feeling intrepid, I grabbed the suspend.d and resume.d scripts from the
.deb and installed them manually. Still the same violent crash.

Is there any reason why applying the commands manually works, but
doesn't on resume?

Many thanks,
J.

[Bug 23497] Re: i8042 unbind required for keyboard/mouse to be useable following suspend/resume & hibernate/resume cycle

[Scott Robinson]

The final release kernel has entered Feisty, so it seems the bug won't
be fixed there. acpi-support hasn't been updated, so that's a no-go too.

After feisty releases, I'll attach an updated version of acpi-support
that will be easily installed rather than the slightly wrong patch that
currently exists.

I had my first keyboard lockup with 2.6.20-14 kernel (no extra patches),
so the bug isn't solved for me either. It's definitely much more
unlikely to appear with this kernel, though.

I have HP nx7400 ey508es and Feisty with unbind patch and suspend to ram
work, but after resume scroll on touchpad doesn't work, I need to go to
console using alt+F1 and back to X using F7, after that scroll work. It
would be nice if someone could tell me how can I get touchpad working
without going to console and back to X.

[Bug 23497] Re: i8042 unbind required for keyboard/mouse to be useable following suspend/resume & hibernate/resume cycle

[JT]

Works a treat on my nx7400 too.
I am also using kernel 2.6.20.14 and acpi-support 0.95, but it did not work by 
itself (only very occasionally as reported by others).
As the patched package kindly supplied by Scott Robinson was for an older 
version of acpi-support, I manually added the scripts from the patch, and 
changed the numbering of the resume script as he suggested later.
Its a shame this will not make it to Feisty final, according to the bug status. 
This type of thing failing is exactly what makes new users say "Linux is 
rubbish - nothing ever works" because they don't understand yet. Therefore, 
IMHO this type of bug should be top priority :-)

I confirm the patch working on my HP nx6310 with Feisty Beta. I would be
glad to see it in Feisty Final.

[Johan Brannlund]

Up until about a week ago, I also had this problem, but it seems to have
disappeared with a recent update.

I've now run about 10 consecutive suspend-to-ram cycles and the keyboard
has worked every time. Either I've been very lucky, or a fix has been
committed to the kernel or to acpi-support.

I'm using kernel 2.6.20-14-generic (amd64) and acpi-support 0.95.

[Jeff Abbott]

Jon,

That used to fix the problem for me in Edgy with my HP Compaq nw8440, so
it's possible that you're seeing the same issue now.  Try running the
following two commands after waking back up:

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

Obviously if you've got no keyboard you'll need to this via ssh or plug
in an external USB keyboard.

If that helps, then the fix listed above would work to resolve the
problem you're seeing with your Dell, too, so I'd snag the suspend and
resume scripts from the patch until they make it into acpi-support
proper.

[Scott Robinson]

Paul, it's getting close to freeze... Is the patch from upstream going
in the kernel?

Or, will you include the scripts in acpi-support? I have tested them on
several laptops, and as far as I can tell they have no ill-effect.
(Which is the expected behavior...)

So, if removing and reloading psmouse doesn't help (I have a Dell
Inspiron 6400), is this not the bug for me? Should I file a new one?
