Toogle display key not working anymore

[Patrick]

Binary package hint: acpi-support

Hi there,

My switch-display key doesn't work anymore. I think it didn't in Intrepid (I don't have an intrepid CD to test now), but it did for sure in Hardy, I've tried. I'd like it to work, since lately I've been working with external displays and it would be nice to have that switch.

The key should be Fn+F10 and in Intrepid lshal -m, xev and acpi_listen all of them reconize the key. In System->Preferences->Keyboard shortcut it gets displayed as XF86Switch. In Jaunty none of them output anything, nor dmesg outputs anything (setkeycodes stuff or anything).

I attach some files which I think could be helpful, some of them from the Intrepid live cd and some from my Jaunty Installation

Thank you for taking the time to report this bug and help to improve Ubuntu.

Please follow the steps at https://wiki.ubuntu.com/Hotkeys/Troubleshooting to help us identify the component that's misbehaving in this case.

Also, you don't mention what model your laptop is - we'll need to know this since the kernel hotkey drivers are each hardware-specific.

Hi again,

I can confirmed it worked with 7.10 and 8.04, but since 8.10 it's broken. The laptop is a Fujitsu-Siemens Esprimo U9200. It has Intel chipset (965GM with X3100 graphics) and wireless.

As for 8.10, I found a CD lying around, and everytime I pressed the key dmesg displayed a message about EC and switch to interrupt mode. I thought I had copied it to a pendrive, but I didn't. If you need I'll boot up the live cd again and post the exacte message here.

As for Jaunty, I attach some files. Killing power-manager doesn't help, and doing input-events does never show anything, not even on pressing working keys.

Running gnome-power-manager in verbose mode also doesn't show anything.

Please tell me if you need anything more.

Thank you!

Hi there,

so I know where the bug comes from: hotkey-setup. Shutting it down completely with sysv-rc-conf and rebooting gave a working key. So I've just uninstalled the hotkey-setup packages and all works fine now.

[Steve Langasek (vorlon)]

Hi Patrick,

This is interesting, because /proc/acpi/video/*/DOS is the last remaining action handled by hotkey-setup in Ubuntu 9.04, and we were already planning to drop this for karmic but hadn't yet due to uncertainty over what this change was originally meant to achieve. If you've removed hotkey-setup and things are working for you, then I would say you've implemented precisely the correct fix on your system. :)

As discussed with Steve, we'll have udev-extras conflict to hotkey-setup, and thus cleaned up on upgrade.

I also tested the remaining hotkey-setup action on my laptop, and it didn't make a difference.

This bug was fixed in the package udev-extras - 20090615+1-1

---------------
udev-extras (20090615+1-1) karmic; urgency=low

  * Update to git 190658b9:
    - Add hid2hci.
    - udev-acl: add sound card input-jack devices.
    - Some bug fixes.
  * Add Conflicts: hotkey-setup, since we have taken over keymap handling now,
    and hotkey-setup only has some old cruft which sometimes even breaks keys.
    (LP: #384511)
  * Add debian/README.source to explain source package structure and how to
    merge to a new upstream snapshot.
