Special Key support incomplete with HP Compaq 6710b

[dukat]

Installation of Kubuntu 7.10 on a HP Compaq 6710b works fine, except some special keys:

Brightness Up / Down keys (Fn F9/F10)don't do anything. Manually setting brightness in Power Manager 0.8 works fine.
They are detected by both ACPI and HAL, though

acpi_listen
video C1AD 00000087 00000000 (down) / video C1AD 00000086 00000000 (up)

lshal --monitor
platform_i8042_i8042_KBD_port_logicaldev_input condition ButtonPressed = brightness-down
platform_i8042_i8042_KBD_port_logicaldev_input condition ButtonPressed = brightness-up

Video-Swich (FN F4) flackers, but doesn't change anything (at least with VGA inserted). xrandr works fine, though

acpi_listen
video C098 00000080 00000000

lshal-monitor
platform_i8042_i8042_KBD_port_logicaldev_input condition ButtonPressed = switch-videomode

Presentation Button doesn't do anything, haven't checked how to change
No ACPI event, lshal gives:
platform_i8042_i8042_KBD_port_logicaldev_input condition ButtonPressed = f23

The Network Switch works, but Network Manager doesn't seem to notice that the network's gone. KbluetoothTray does react, though
No ACPI, lshal gives

Hi Dukat,

Not sure why I didn't ask you this earlier but care to test with the latest Hardy Alpha release to verify this issue still exists? The Hardy Heron Alpha series was recently released which contains an updated version of the kernel. You can download and try the new Hardy Heron Alpha release from http://cdimage.ubuntu.com/releases/hardy/ . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/ . Thanks.

I just installed the latest Kubuntu Hardy beta and pulled the latest updates

- Brightness buttons: Work now. Yay!

- Display switch: still the same issues

- Wireless network Switch - still the same issues

- Presentation Switch - still no reaction

- There also seems to be a new bug introduced now: When I press the info button, I get a segfault signal 11 in KDE Daemon (kded). Here's the backtrace:

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[Launchpad Janitor (janitor)]

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

I've just updated to Kubunuty Jaunty 9.04 latest Beta

Most keys work, except Fn-F3 (Sleep) or Fn-F8 (Show Power)

Fn-F3 is catched in xev, but doesn't seem to be mapped to anything:
KeyPress event, serial 34, synthetic NO, window 0x4000001,
    root 0xc2, subw 0x0, time 6963639, (-35,769), root:(667,794),
    state 0x0, keycode 150 (keysym 0x1008ff2f, XF86Sleep), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

Same goes for the Battery button
KeyPress event, serial 34, synthetic NO, window 0x4000001,
    root 0xc2, subw 0x0, time 7054314, (-201,692), root:(501,717),
    state 0x0, keycode 244 (keysym 0x1008ff93, XF86Battery), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

Doesn't seem to be mapped to anything.

Works in Jaunty 9.04

The previous "Works in Jaunty 9.04" only applies to the network-manager status change...

[Jonathan Thomas (echidnaman)]

The Kubuntu hotkeys you are experiencing are currently being tracked as bug 293213.
In the future, you should probably consider reporting one bug per issue, instead of lumping them all together into one.

[Jim Lieb (lieb)]

As a kernel bug, this invalid. The events are being passed to the upper layers (QT) where they are being ignored. These issues are being tracked in the bug(s) cited in earlier comments.

[nebu (subs-zero)]

The same problem persists in Ubuntu 10.04 the presentation key is still not working
