[Bug 310270] Re: Dell XPS M1330 volume keys as pressed two times

[Augusto]

I confirm this bug on Kubuntu Jaunty 9.04 (freshly upgraded from Intrepid) on a Dell XPS M1330.
All multimedia keys worked fine for me in KDE 3.5 and I see this wrong behavior since KDE 4.1 (the first version I tried on Kubuntu 8.10).

I have attached in the related bug on KDE bugtracker
(http://bugs.kde.org/show_bug.cgi?id=178501) three different tests I
just perfomed using xev and hitting two different buttons (Mute and
VolumeDown) _just one time_.

The first test is done outside KDE (I opened a second X server and
launched xev from a xterm there, see attachment comments in the KDE
bugtracker). You can see that only two key presses/releases are
correctly detected.

The second test is done in a KDE 4.2 session, after closing KMix. You
can see that multiple key presses/releases are wrongly detected.

The third test is done in a KDE 4.2 session, with KMix running. You can
see that only multiple releases are detected (here also some focus
changes are visible). KMix seems to "steal" key presses, but not key
releases.

My conclusions from these tests are the following:
- It is not an hardware problem.
- It is not a kernel/driver problem.
- It is not a Xorg bug (at least not Xorg taken alone).
- It is related to KDE (outside a KDE session keys presses/releases are detected correctly).
- It is not a KMix bug, multiple key presses/releases are detected also after closing KMix, but I don't know if it's normal that KMix is stealing key presses, but not key releases from xev output.

So the question remains: what is the best place to report this bug?

I conclude saying that sometimes, but rarely, something "magic" happens (maybe when I play with xev) and suddendly all buttons begin to work correctly inside KDE and with KMix running. Today it happened just one time, but after a reboot the multiple key presses/releases came back. :(
I don't know what triggered the correct behavior; if I will discover it, I will write here a follow up.

Thank you for your attention!
