Intrepid AMD64 regression: Zepto 6625WD audio keyboard keys don't work correctly anymore

[Jean-Paul]

On the Intrepid AMD64 beta (and at least alpha 5 and 6, I've tested it), when I press the volume up and volume down buttons (hardware) on the side of my laptop, the volume levels shoot up / down to the max. and min. respectively, and the applet *keeps* trying to highten/lower the volume level (which is master, I think, so the actual level being modified is ok, it's just the modification that is horrid).

Next to the above, Gnome largely becomes unresponsive (e.g. I can't enter text in text fields / text areas anymore) and the only thing that "works" as a workaround it restarting X (in my case, via ctrl+alt+backspace). Maybe manually restarting GDM works as well, but I haven't tested that.

I stated in the title that it is a regression, because in Hardy this did work correctly.

The exact same problem is also happing with Intrepid release candidate, in my HP Pavilion ZV6000 laptop.
The only solution is to hit the ctrl+alt+backspace keys.

I can confirm the same in 8.10 sharp release with a Zepto 6625WD

I can also confirm this bug.

System:
Compaq Presario R4000

OS:
Ubuntu 8.10 Intrepid Ibex
Fresh install from i386 LiveCD

It seems that this effects not just the AMD64 version but i386 as well. <a href="https://bugs.launchpad.net/ubuntu/+bug/268647">Bug #268647</a> is marked as a duplicate of this bug.

I can confirm this bug on a Zepto Znote 6615WD with up-to-date Ubuntu Intrepid i386.

In fact the problem seems that X.org sends continuous KeyPress/KeyRelease events for those keys after they have been pressed just once, as revealed by the following xev output:
(first assign raise/lower volume to another keystroke)

Notice that if I close xev then re-launch it, it does not receive those events until I press that key again.

I can also confirm this bug.

Compaq R4125 (R4000 series)
Ubuntu Intrepid 8.10 (kernel 2.6.27-7-generic)

I am using compiz, but the bug exists with it disabled as well. Have not tried uninstalling video card driver (it's a pain), but I am seeing the same thing as LordFarquaad (killing xev stops it and does not continue when new xev session created.)

Volume worked flawlessly in Hardy and Gutsy, now it does not work in Intrepid.

Also note: I am no longer able to suspend (couldn't in hardy either, but could in gutsy). I have a good feeling my laptop does not like the current version of X :(

[JPL (x-launchpad-jplanglois-com)]

same here... compaq r4000. no problems with 8.04 or 7.10.

[Crim Soukyuu (chrno-sphered)]

Problem still persists in 13.04 - very annoying.

Jean-Paul, thank you for reporting this bug to Ubuntu. Intrepid reached EOL on April 30, 2010.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases
