Bug Description

When using Volume function buttons on Dell Studio 15, the volume start increasing to maximum or decreasing to minimum.
Then menus on the upper and lower bar become unusable and it is impossible to use the keyboard to input text: furthermore it is not possible to move windows (upper window bars get insensitive).
Ctrl-alt-canc keeps working: this is the only way to reboot.
The kernel is Lucid Lynx beta 1; the computer is new, so I don't know if the bug affects other kernel versions.

I experience the same problem on the same Dell Studio 1558 model.
The problem still occurs in 2.6.32-19-generic #28~pre1 SMP Wed Mar 31 14:57:35 UTC 2010 x86_64.

More recovery notes: after getting into the bad state, you can regain a working desktop by switching to Ctrl-Alt-F1 then back to Ctrl-Alt-F7 again (note that on this Dell model, you might actually need to press Ctrl-Fn-Alt to enable the "regular" numbered F-key functionality, depending on BIOS configuration).

Unfortunately for these machines they do not get the grand Ubuntu enablement treatment other Dell machines get. Also this issue can only fix with Ubuntu 10.04 at this point (some new infrastructure to handle problems like this).

            If you install 10.04 beta. Copy the file I have attached to this comment to /lib/udev/rules.d/

            Report here if it works or open a new bug and report that here.

Got a hold of a 1558 & the fix does work. Submitted to upstream udev. May make it into 10.04.

Thanks Jerone -- yes, I also confirm the fix for the Dell Studio 1558.

I also note that there are reports of the exact same problem on other (non-Dell) laptop models (LP: #42043, LP: #374884). The same fix is likely to work for them too. Would you like to address those bugs, or should I?

Moved this bug report over from bug #465250

I'm running Karmic (9.10) amd64 on my Dell Studio 1558 (Intel Core i3 processor) and I also experience this bug.

The mute key (F7) works fine.
But the volume up (F9) and volume down (F8) keys have problems
Not only do they not stop increasing (or decreasing) in volume, but my computer becomes unresponsive.
I find myself having to press control + alt + delete to restart (brings me back to the good old days of Windows!)

Looking forward to a fix.


Thank you for the file. So if I understand correctly, copying 95-keyboard-force-release.rules to /lib/udev/rules.d/ will only work on 10.04, and not on 9.10?

@Matt -- that is correct: The 95-keyboard-force-release.rules method is only applicable to 10.04 Beta -- it will not work for previous releases.

Fixing this for 9.10 requires a fix in the kernel itself. I am going to try to extend the in-kernel fix for the Studio 1557 (now pending for release in 9.10) to also work for the Studio 1558.

Ubuntu 10.04 Beta users can install a test fix for this problem from this PPA:

The PPA applies a fix similar to the method outlined by Jerone in comment #3 (either method works just as well for the Dell Studio 1558).

 I suffer the same problem in my HP 6730b.

 When I press the "+" or "-" volume function keys (tactile keys between keyboard and screen) then the key blinks like if it's being continously pressed and notify-osd shows in the screen the volume meter until I reboot the computer.

 The notify-osd "volume meter" then appears continuosly and it sometimes steals the keyboard focus and mouse motion so I have to reboot to continue working correctly in my lapton.

 Those keys worked perfectly in 9.04 and 9.10, and have started working incorrectly after upgrade to 10.04.
