On a Toshiba Satellite Pro U300 laptop (and others with the Pro series), there
is a volume dial on the side of the laptop, which is used to control the sound
volume.

It works on Fedora GNOME 2.22.1, but incorrectly.

Even slightest move up of the dial, moves the volume all the way up. The volume
control beside the clock shows the setting is in effect, also the volume icon
popup shows the volume all the way up.

The same happens with even slightest move the volume dial down. It turns the
volume all the way down, showing the mute sound icon beside the clock on the
panel and on the popup.

Aditionally the move breaks the keyboard handling. After the volume all up/down
keyboard is left in a non-working state. The signalling is still on because the
volume popup stil shows and disappears consistenly showing the max/mute icon.

I tried to see what keycodes the volume dial sends using 'xev', but since the
keayboard handling breaks during the dial move, I couldn't get much information
of it.

To get my keyboard working back, I need to switch to text console (Ctrl-Alt-F1)
and back to graphical console (Alt-F7).

First, gnome-audio has nothing to do with your problem. gnome-audio is a package
with a bunch of audio files to be played when certain events occur, ie. an audio
theme.

As for using the dial "breaking the keyboard handling", I'm not quite sure what
it means. You could try using the dial on the command-line instead, with a tool
like evtest (not packaged, look for evtest.c on google), or printing whatever
xev gives you back (even if you need to switch VTs to get to the result).

My guess is that this Toshiba laptop needs a driver to make this button work
appropriately. Reassigning to the kernel, where hopefully somebody will have the
hardware to test this, and point the finger back at GNOME if it's indeed the
culprit (unlikely).

This is not a kernel problem.

This volume dial sends normal multimedia keyboard VolumeUp and VolumeDown
keypresses. But I guess with some additional keycodes. In GNOME Keyboard
Shortcuts these are correctly identified as XF86AudioRaiseVolume and
XF86AudioLowerVolume.

Under textmode console there is no problem. Turning the volume wheel yelds some
~ characters on screen only, but the keyboard is still working.
Under XOrg, once I move the volume dial, keyboard is not working anymore. Maybe
it is switched to RAW mode or something? (I don't know the exact X internals).

So, this is more likely XOrg/GNOME problem, not kernel.

I would gladly help debugging it, but I do need some guidance.

Schiphol,

The Satellite U500 indeed is still missing, I'm happy to add it
upstream. However, are you sure that this works with "SATELLITE"? All
other machines seem to advertise themselves as "Satellite".

Jerome Young's fix also works for the analogous problem with volume keys
in the Toshiba Satellite U500, by adding "SATELLITE U500" to the list.
That is,

 ENV{DMI_VENDOR}=="TOSHIBA", ATTR{[dmi/id]product_name}=="Satellite
U300|Satellite Pro U300|Satellite U305|SATELLITE U500", RUN+="keyboard-
force-release.sh $devpath common-volume-keys

[PabloAB]

I finally solved with the fix of Jerone Young (Comment #95) but with something 
else, adding "Satellite U305"
which is the output of the command:  sudo dmidecode -s system-product-name
So my line is:
 ENV{DMI_VENDOR}=="TOSHIBA", ATTR{[dmi/id]product_name}=="Satellite 
U300|Satellite Pro U300|Satellite U305", RUN+="keyboard-force-release.sh 
$devpath common-volume-keys

This is a common issue with volume key getting stuck. You have to fix
via udev (as this is to no longer go in the kernel).

For Volume key issue in 10.04 you can fix simply by adding the following
line before  LABEL="force_release_end" in /lib/udev/rules.d/95-keyboard-
force-release.rules

[Bug 271706] Re: Toshiba Satellite U300 volume wheel sticking

[Aryeh Gregor]

If you're using 2.6.32 or later, you should be able to fidget with the
contents of the force_release file in /sys to add the appropriate
keycodes.  The exact values can be found by experimentation, and you can
add something to /etc/rc.local to set it on startup if you like (changes
will not persist across startup).

[MacRules]

This bug still affects me on My Mivvy G310 netbook (seems Viooo Corp PT17 
model).
Is there an easy way to apply the fix to adress this machine too?
The problem is also that showkey shows no release events for my volume keys.

[Bug 271706] Re: Toshiba Satellite U300 volume wheel sticking

[Aryeh Gregor]

I took a stab at fixing the "multiple keypresses" thing, but eventually
gave up.  It doesn't seem worth it -- volume control works okay as-is,
and I'm concerned that maybe in some cases it will start emitting only
one keypress at a time and break any fix.  We just need to wait for
userspace support for this quirk detection, I guess?  At any rate, now
there's a very good workaround with 2.6.32+, it just needs to be applied
automatically.

After upgrading to karmic with 2.6.32-10-generic kernel and adding
174,176 to /sys/devices/platform/i8042/serio0/force_release the bug is
finally gone. :-D

Bolting it to /etc/rc.local and I'm done. :-)  (This is a workaround,
not a _proper_ solution, but it works for now.)

[Bug 271706] Re: Toshiba Satellite U300 volume wheel sticking

[Aryeh Gregor]

On 2.6.33-rc4 (presumably also 2.6.32), this mostly works:

sudo bash -c 'echo 174,176,`cat
/sys/devices/platform/i8042/serio0/force_release` >
/sys/devices/platform/i8042/serio0/force_release'

(I figured out 174,176 by binary search.  Protip: don't force_release
anything in the range 0-127, since that will prevent keycodes like Ctrl-
Alt-F1 from working . . . I had to hard-reset my computer.)

The volume control no longer goes crazy when you turn the dial.  But
it's not a complete fix -- as noted, the dial sends three or four
keypresses at once, so this results in the volume jumping instead of
increasing smoothly.  A quirk probably does need to be added to the
kernel after all, which will cut out the duplicate keypresses.  I'll
look into writing that.

Yes, I still have the user visible symptoms.
I guess the key-up, key-down sequencing is fixed in 2.6.33, so it works for you.

I'll try getting Lucid kernel and playing with sysfs.

This bug has been sitting in Ubuntu for years now, so I guess Lucid fix
is enough.

[Aryeh Gregor]

Tomasz: I wrote the patch against 2.6.33-rc4, so I'm not surprised it
doesn't apply to an older kernel.  To clarify, are you still getting the
user-visible symptoms even with the patch?  When I tried it, I stopped
getting the symptoms (volume indicator maxing out and flickering,
keyboard freezing up, etc.).  The volume wheel seemed sluggish/jittery,
but it behaved much better.  I did seem to still be getting similar
codes from showkey -s, but I assumed those were somehow not relevant,
since it mostly worked.

I'll try out the sysfs thing when I get access to the machine again.  Do
you know where this sort of change would be added in HAL/DeviceKit?  Are
there any example patches?  2.6.32 means Lucid, so a quirk would still
be needed if we wanted to fix it for Karmic, I guess (maybe not worth
it).

The kernel patching method for adding quirks is not relevant for 2.6.32+ 
kernels.
The forced_release quirk is accessible via sysfs and it's up to HAL/DeviceKit 
to add proper quirk.

Nick Moeck: your patch is invalid. You need to edit the @ modified
section delimiters to have a valid patch.

Aryeh Gregor: I tried applying your patch on linux-image
2.6.31-17-generic but it does not apply:
'atkbd_volume_forced_release_keys' is not in standard kernel. I've fixed
it and you will find the 'generic' patch attached.

Nevertheless it does not fix the problem. See the following evtest

First is 'Space' keypress and release. The second is turning the wheel one 
notch Up.
a) the event is repeated 3 times - looks like the anti-repeat in 
drivers/input/keyboard/atkbd.c:482 does not work in this case
b) even with atkbd_setup_forced_release quirk the sequence is wrong - this is 
why I posted Space keypress for reference
VolumeUp key is depressed (0) then pressed (1) three times
This leaves the button in pressed state, causing the "sticking" behavior.

thanks for the attempt, I'll try myself the patch as soon as I manage (I

that 3GB aren't enough). However, I suspect that this is not going to
work to me since the output of the dmidecode says:

I believe this case can easily be integrated in the patch though.

[Bug 271706] Re: Toshiba Satellite U300 volume wheel sticking

[Aryeh Gregor]

For anyone who's not clear how to test: compile a kernel using the
instructions at ,
with my patch applied.  You'll have to work around bug 498747, for
instance by doing "git checkout v2.6.32" to use an older kernel so it
compiles cleanly, or by applying the patch given there when (if) the
compile process fails for 2.6.33.  Compiling the kernel using those
instructions took about two hours on my U305 (100 minutes to actually
compile and then 20-30 minutes to make the .deb), so make sure you have
something else to do.  Say here whether or not it helps, and post the
output of "sudo dmidecode | grep -e Product -e Vendor".

Also, whether or not you want to test, if anyone is affected by this but
"sudo dmidecode | grep Product" does *not* output exactly either
"Satellite U305" or "Satellite Pro U300", please say so so that your
model can be included in the fix, since it won't be at present.

Finally, thanks to everyone who posted critical info here, particularly
jetdog, ktemkin, and the people who posted their DMI info -- I'm a PHP
programmer and barely touch C code, so I was basically just copy-pasting
to write the patch, and wouldn't have had a clue how to proceed without
the exquisitely thorough explanations and pointers given earlier in the
thread.

Nice!  Way to squash those bugs!  I can't confirm this myself since I

from the kernel team to build a test kernel with this.

Then we can get more confirmations from others, and submit to mainline

Particularly, it would be great if we could have somebody with at Toshiba U300 
to test this.

I am assigning this bug to myself, since I am working on a patch for
this bug.  From what I can gather, all models of the U305 series have
the same DMI_PRODUCT_NAME, same with the U300.  Since I am completely
new to kernel development, this might take me a little while, since I
have to learn how to actually do this kind of stuff, but since I am
affected by this bug, I want to fix it :) Please bear with me while I
learn.  My goal is to have this fixed in time for Lucid, but I estimate
that I'll be able to get it resolved much sooner than that.

The DMI information gathering is good.  Whoever is making a patch will
need the whole array of U300 DMI_PRODUCT_NAME (s).

As we've already seen, a U305 has come up.  I did some light research
and it seems that only the U300 and U305 are in this series.

If anybody has anything in the U300-series that is not a 300/305, please
reply so that we can target your DMI info in the patch.

"Where do I find DMI_SYS_VENDOR and DMI_PRODUCT_NAME?"

Those are part of the Microsoft DMI information, provided by the
physical hardware.  There is no giant list of which one gets what DMI --
so we just test a few and see if our findings are consistent.  It is
used for identifying hardware to kernels and software.

(That DMI flag and your scancodes is about all you need to quirk
atkbd... and a tiny bit of C =D)

[Bug 271706] Re: Toshiba Satellite U300 volume wheel sticking

[ktemkin]

I might be able to find time to write a kernel quirk over the holidays;
currently I'm up to my eyebrows in work.

Similar quirks exist for other machines already, see this link for a sample:
https://lists.ubuntu.com/archives/kernel-team/2009-April/005480.html

If everyone subscribed and still experiencing this problem could post
their DMI_SYS_VENDOR and DMI_PRODUCT_NAME, it'd be helpful.

The patch I offered above for evdev is designed to mask your symptoms;
which is useful during the wait- but a better option still would be to,
in conjunction, remap the volume up/down keys to another keyboard combo
and avoid touching the wheel. Avoiding those keys altogether will
minimize the spurious CPU usage until a quirk is done.

Again, my 'fix' is pretty much a crude hack for evdev that filters out
the additional events at the X-input level. It will not fix the
underlying problem- the kernel.

Good luck, and if anyone wants to try their hand at quirking the kernel,
I'm sure you'd have plenty of ready testers. If not, hopefully I'll get
to it before too long.

To all developper's attempting to fix this bug:

This problem exists in the __kernel__.  Not in evdev.  Not in X.  Not in
Gnome, KDE, or anywhere else.

Quirking the evdev driver does not fix this problem - and your evdev
driver AND the kernel will probably be faced with increased CPU time as
a result of key-event message passing.  What happens is that once the
kernel starts spamming the volume up/down key signals to the various
kernel/X input handlers (i.e. anything that begins with
xf86-input-), X gets spammed with key events, causing the lockups
you're describing.

The reason the kernel spams evdev is quite simple:  We have logs earlier
in this thread that indicate that the physical hardware implementing the
PS/2 protocol on the keyboard do not create a release event for the
volume buttons (this wheel produces "down" ticks, but
__does_not_always__ produce "up" ticks).

Quirking evdev, as per the solution by ktemkin described in this thread,
and on a repeatedly referenced ubuntuforums post, will __not__ stop this
increased key-event message passing!  It will only cause evdev to ignore
the respective key signals from the kernel, but it is an extremely
hackish-fix,and your kernel input handling will still be highly clogged!
Also, the problem will reoccur if you (or ubuntu official) were ever to
switch away from using xf86-input-evdev.

The problem starts WAY earlier than evdev.  It (likely) exists in the
input/drivers/atkbd.c kernel input driver.  What this fix needs is a
quirk for the key scancodes that are not producing "release" events, so
that the linux kernel can give "keyup" events for evdev, any other
xf86-input handlers, and the resulting userspace applications that use
these input handlers.  Then your volume wheel will work normally.

We need to get some kernel bugfixers in here!  I would fix this myself,
but real-life work is unfortunately taking the majority of my time.

I hope this will jumpstart a fix -- i know it's rough trying to find
someone to get this stuff done!

[Romano Giannetti]

I think that bug#273745 and bug#288134 are duplicate of this one. I have
a U300 too and it happens to me.

Really old one. I will try the fix.

I can confirm on Karmic as well. I found a simpler workaround was to
simply remap the sticky buttons. In my case the volume buttons stuck, so
I remapped volume up to "shift + right arrow" and likewise for volume
down and mute. Now the the volume control keys don't stick.

I notice that, at least on my computer, after initiating the volume
problem, putting the computer to sleep and then resuming from sleep
fixes the disabled keyboard problem.

[Bug 271706] Re: Toshiba Satellite U300 volume wheel sticking

[Richard]

Thank you to everyone working on this.  I am new to Ubuntu - installed via Wubi 
on a Toshiba U305-S5127.  I am experiencing this same bug and look forward to 
the solution.  I am a newbie and not particularly tech-savvy so I am hoping 
that there will be a step-by-step guide for those of us who are not tech 
guys... I would like to switch over completely to Linux to support open source 
and avoid supporting more corporations than I have to!
Thanks.

[Bug 271706] Re: Toshiba Satellite U300 volume wheel sticking

[ktemkin]

I think I can almost see their design rationale, especially if they
wanted the controlling logic to be compatible with more than just their
volume wheel- but deviations from any standard are almost always more
headache than they're worth for developers, especially when
documentation isn't available.

@jetdog:
My U305 has a compatible keyboard module, I can compile and test any kernels 
you provide.

Looking at various source versions of the old 'kbd' drivers, I'm of the
opinion that it might be best to also hack a fix in input_evdev. It
doesn't exactly address the source of the problem, but quirking the
kernel for all of the keyboard configurations that suffer this issues
will be a long and arduous process, especially considering all the
testing and scrutiny a change has to be placed under before it can make
it upstream.

Wouldn't it be better to, in addition to quirking the kernel, provide a
hack in evdev with a single additional non-intensive call that would
provide more immediate relief to the users? This is what was done in the
'kbd' drivers, though those used a different method of determining key
events.

[Bug 271706] Re: Toshiba Satellite U300 volume wheel sticking

[jetdog]

I have cleaned up the duplicates for this bug, and changed the summary
to deal with only the U300.

If anybody is subscribed to this bug and does not own a U300, please
search for a volume repeat/stuck problem related to your hardware, to
keep things organized for the maintainers.  Unfortunately we have to
deal with these keyboard quirks on a hardware-to-hardware basis.

As far as a patch goes for the U300, I will see about writing one for
this system, based on the above information.  I'm not sure if what I
have in mind will work, but I will try to write a patch for the U300 for
on the current Ubuntu kernel - and then hopefully someone in this bug
subscription is comfortable/capable of compiling an ubuntu kernel to
test it on a U300.

(Although I must say, this one is the most unique keyboard hardware
quirk I have seen yet).

To illustrate this hardware quirk, for those trying to understand it (or those 
curious =D):
Wheel Up = on, off, on, off, ON (so keep sending from this point on)
Wheel Down = on, off, on, off, ON (so keep sending from this point on)
But when we do it again:
Wheel Up = negate last "up" state (so OFF), on, off, on, off
Wheel Down = negate last "down" state (so OFF), on, off, on, off
cycle complete.

I will do my best in the absence of any accountable logic on your part,
Toshiba xD
