Multimediakeys crashes on pressing

Hi mz-88,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

Hi Bryce Harrington,

i've attached the `lspci -vvnn` output.

Greetings

I am experiencing the same issue on a Zepto 6625wd. My system doesn't crash, but after pressing the up or down volume keys gnome no longer responds to key presses, although the mouse pointer is still responsive. Gnome becomes responsive again if I switch to a virtual terminal and then back again.
I was following https://bugs.launchpad.net/ubuntu/+source/linux/+bug/261721 (of which this bug was marked as a duplicate) as that bug seemed to be closely related. However, it seems that the 2.6.27-8 kernel contains a fix for #261721 that has not solved my issue and so this bug report has been removed as a duplicate.

As stated in the description, it seems that there is a problem with the generation of the key release event. Running xev from a failsafe terminal (straight after a reboot) and pressing the volume up key twice gives:

$ xev

...
MotionNotify event, serial 23, synthetic NO, window 0x400001,

...

Note that the key release event is only generated when the key is pressed for the second time.

I haven't made any modifications to xorg.conf.

Same problem for me on a Toshiba Satellite U305, after changing the volume the volume bar graph stays blinking on the screen and the keyboard and right mouse button stops responding. Going to a virtual terminal and comming back make it work again.

Hello. I've got exactly the same problem as described by Edmundo Valle Neto, on a Toshiba Satellite Pro U300.

See https://bugs.launchpad.net/bugs/330259

The problem is still present in 9.04.

The problem is still present in 9.10.

This problem was fixed for me in 9.04 (Zepto Znote 6625WD).

Steffen, is this fixed for you as well?

For anyone else - the title of this bug describes a fairly generic symptom; if you think you're having the same problem it would be better to file a separate bug report, unless you have exactly the same hardware as Steffen.

This was fixed for me in 9.04, too.
Thanks

For me it's still not fixed in any release. My bug#295141 was closed as a duplicate of this one. All the requested info from me is attached there.

Hi Steffen,

This bug was reported against an earlier version of Ubuntu, can you
test if it still occurs on Lucid?

If you are the original reporter and can still reproduce the issue on
Lucid, please run the following command to refresh the report:

If you are not the original reporter, please file a new bug report, so
we can work with you as the original reporter instead (you can reference
bug 291612 in your report if you think it may be related):

The description given by Graham Whelan on 2008-11-12, is almost the same that I'm getting on a Olivetti 820 notebook, running lucid from the Live CD. I'll would also add that my keyboard locks.
The system has a 8.04 installed, with no issues.
I have tested seven different distros, with KDE, Gnome and Xfce. The only two that are OK for me are 8.04 ans Trisquel Pro 2.2.2 i686 Live DVD, both with xorg 1.4.0.90.

Running the command showkeys in a text terminal shows that the volume up and down keys (Fn F5 and Fn F6 in my system) only issue a key press event, but NO key release event.
