Hi Mohammed,

Hi,

upstream commented on your bug on
<https://bugs.freedesktop.org/show_bug.cgi?id=11515>:

"It looks to me like a bug in the keyboard driver (X or kernel). The key
should not endlessly generate X events when it is not actually pressed
(do I understand you right?)"


Hi Gilles. Please answer the mail above or I will have to close the bug
report.


The description above was correct, the key is pressed and released about
one second later. Starting from the moment it's pressed, X events are
generated endlessly.

Unfortunately, I no longer own this laptop, so there is little I can do
now to help.

However I've tried a kubuntu feisty 7.04 release, and I had the good
surprise to see that all special keys (volume up, volume down, ...)
were correctly managed. Sorry, but I didn't investigate much more.

Gilles.

not better  :(

in xev, pressing and releasing once the VOL-DOWN key leads to
the following endless burst of events:

It only ends when pressing another key

May be an interesting thing: it seems that the 1st received event
is a KeyRelease... does it make any sense ?

Thanks,
Gilles.

The problem still exists using an update to date sid.

Is there any thing I could do to investigate the issue?

Bug#355822: xkb: some multimedia sends events forever once pressed

[Gilles Grandou]

Package: xlibs
Version: 6.9.0.dfsg.1-4
Severity: normal


My laptop is a CLEVO D500P.
If I press some multimedia keys (like VolumeDown or VolumeUp), X events 
are sent forever, until I press another valid key.

Under console, running showkey -s:
pressing VolumeDown returns the next sequence:
0xe0 0xae 0xe0 0x2e 0xe0 0xae 0xe0 0x2e 0xe0 0xae 0xe0 0x2e 

unlike normal keys, the sequence e0ae-e02e is repeated until I release 
the key.

Under X, using xev:
KeyPress and KeyRelease event are sent forever, until I press another 
valid key. Here is the few first line of the xev log:

KeyRelease event, serial 28, synthetic NO, window 0x3c1,
