Hotkeys for HP Compaq 6730b

[Scott Robinson]

Binary package hint: hotkey-setup

I purchased a new HP 6730b. The brightness keys (Fn-F9 and Fn-F10) weren't functioning. I modified the hp.hk appropriately.

See the attached diff.

Thanks Scott but in mine HP 6730b with Ubuntu 8.10 and Kernel 2.6.27-7 (or 8) the brightness doesn't change. The display shows the "sun popup" but nothing change in the brightness. This is my hp-hk file modified:

 setkeycodes e001 $KEY_PROG1 # Fn+Escape?
 setkeycodes e008 $KEY_PRESENTATION # Presentation (Misc 1)
 setkeycodes e009 $KEY_BATTERY # Battery
 setkeycodes e00a $KEY_COFFEE # Lock
 setkeycodes e00c $KEY_SOUND # Music
 setkeycodes e00e $KEY_MEDIA # DVD
 setkeycodes e012 $KEY_BRIGHTNESSDOWN # Brightness Down
 setkeycodes e017 $KEY_BRIGHTNESSUP # Brightness Down
 setkeycodes e031 $KEY_HELP # Help
 setkeycodes e059 $KEY_HELP # Another help key

is it correct?

The brightness doesn't change because of <a href="https://bugs.launchpad.net/ubuntu/+source/xbacklight/+bug/176888">another bug</a>.

Works fine!

$ xrandr --output LVDS --set BACKLIGHT_CONTROL native

 thanks Scott!

I changed the /usr/share/hotkey-setup/hp.hk file and ran the xrandr --output LVDS --set BACKLIGHT_CONTROL native command under Ubuntu and it fixed the issue.

Now I installed Kubuntu Jaunty Alpha 4 and the same solution doesn't seem to work. The /usr/share/hotkey-setup/hp.hk file didn't even exist (when I had Ubuntu, it existed and I just had to add the brightness keys to it).

Any ideas? Thanks in advance!

No problem with Ubuntu 9.04 on my HP 6730B, I can update de brightness...

[Paolo (paolomelchiori)]

Me too, everything, about display, works in 9.04.

[Vítor E. Silva Souza (vitorsouza)]

Still the same issue in Kubuntu 9.04. hp.hk file doesn't exist, hotkeys don't work, can't set Fn+F9 as shortcut in System Settings because Qt says it's an invalid keystroke. See https://bugs.kde.org/show_bug.cgi?id=182672 for details.

This appears to be handled now by default in /lib/udev/keymaps/hewlett-packard in Ubuntu 9.10:

0x92 brightnessdown # FnF7 (FnF9 on 6730b)
0x97 brightnessup # FnF8 (FnF10 on 6730b)

Closing as resolved.
