Description AL13N 2011-04-16 00:41:13 CEST

Description of problem:

on an acer laptop, there's a group of 5 buttons on the left side of the keyboard.
among which are enabling wireless (which works), the rest fails:

icons (from top to bottom):
1. no idea what it means it's like sort of an "i" like info (dmesg lists some kind of keycode)
2. wifi: OK
3. browser: nothing happens
4. mail: nothing happens
5. bluetooth: backlight becomes maximized

to be completely fair, i never before tested out the bluetooth button or functionality on this laptop, on any OS.

Reproducible:

Comment 2 AL13N 2011-07-27 21:52:34 CEST

yes, still present.

how do you mean what hardware? what do you want to know?

Comment 3 Ahmad Samir 2011-07-31 10:42:20 CEST

To file a bug report upstream, follow the instructions in /usr/share/doc/udev-doc/README.keymap.txt

Source RPM: (none) => udev

Comment 4 AL13N 2011-07-31 12:24:03 CEST

are you sure this is a udev error? wouldn't it be in some driver or something?

Comment 5 AL13N 2011-07-31 12:24:54 CEST

oh and how exactly should it enable bluetooth? i can't seem to find anything like it, perhaps that key should power it on/connect it to usb bus?

And again: still present?

Which Acer laptop is it? At least model/type number, and if the keyboard layout isn't the same on all models with that number: the keyboard lay-out as well.

Acer Aspire 7530G Series - 724G32MN

this is a belgian azerty keyboard layout (but don't think the side buttons are part of keyboard?)

@ AL13N

I understand the problem is still there.

If you can replace the keyboard without replacing those buttons, indeed, than the side buttons aren't part of the keyboard :)
 
Anyway, I thought those easy launch buttons were set in the keymap, because I've seen things like: 
245         0x1008ff94 (XF86Bluetooth) 
in a keymap, but now I discovered that there is no relation between the keycode of those buttons (as shown with showkey) and what's behind that keycode in the keymap. I guess those keymap settings are overruled by some settings somewhere else.

In /lib/udev/keymaps/acer, I found:

0xD7 bluetooth # (toggle) on-to-off
0xD8 bluetooth # (toggle) off-to-on 

There are more acer's in /lib/udev/keymaps, but no 7530G, so I guess Ahmad was right after all that you should report upstream. The document he referred to, isn't there, btw.
If you do report upstream, please put the link to the report in the URL field

Comment 9 AL13N 2011-10-17 18:28:34 CEST

i saw keycode 233 when using xev on it but it was bound to XF86ScreenBrightnessUp or something. i'm wondering if this udev thing can be used for that. anyone know?

Comment 10 AL13N 2011-10-17 21:10:51 CEST

ok, i've been trying to test this locally before i update

i've seen some other exceptions to acer rules that enable bluetooth on 0xD9 (which is the key), so i modified the rules file and rebooted, but it appears it's still bound to brightnessup instead of bluetooth...

do i need to remake an initrd or something?

Comment 11 AL13N 2011-10-18 00:47:28 CEST

ok, i sort of found out how it works, but then come to the conclusion that likely this laptop may not even have a working bt, it's totally unclear, but having no rfkill entry, i'm giving up, closing issue.
