[Lucid Alpha3][khk-004 testcase failed] Click on Internet hotkey opens Home folder on Acer Laptops

Laptop Report
https://wiki.ubuntu.com/Testing/Laptop/Reports/AcerTravelMate6593G

If I click on Internet key when firefox window is focused it opens the firefox homepage correctly.

If the focus is on the Desktop, it opens the Home folder.

Obviously if I click it when Firefox is closed, it opens Home folder.

It also affects Acer Aspire 1640.

Laptop report: https://wiki.ubuntu.com/Testing/Laptop/Reports/AcerAspire1640

sergio@sergio-desktop:~$ sudo /lib/udev/keymap -i input/event3
Press ESC to finish
scan code: 0xB2 key code: homepage

which is wrong, should be www.

sergio@sergio-desktop:~$ xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'
keycode 180 = (keysym 0x1008ff18, XF86HomePage), state = 0x0
keycode 180 = (keysym 0x1008ff18, XF86HomePage), state = 0x0

P.S.:Another strange thing if that it printed it twice.

keycode should be 158

sergigno@entropy:~$ xmodmap -pke | grep XF86WWW
keycode 158 = XF86WWW NoSymbol XF86WWW NoSymbol XF86WWW

Please exercise the steps in /usr/share/doc/udev/README.keymap.txt.gz, "Fixing broken keys" and find out the scan code for that key. Thanks!

In comment #9 I already find out the scan code:
scan code: 0xB2 key code: homepage

In attachment you have the current mapping too.

From /usr/include/linux/input.h should be:

KEY_WWW 150 /* AL Internet Browser */

In /lib/udev/keymaps/ there are some acer-related files:
acer
acer-aspire_5720
acer-aspire_5920g
acer-aspire_6920
acer-travelmate_c300

Is there a way to understand which I am using?

This bug affects both Acer TravelMate 6593G and Acer Aspire 1640

Only acer-aspire_5920g contains 0xB2 code this way:

0xB2 www

I read /usr/share/doc/udev/README.keymap.txt.gz

There is only a thing I can't understand.

scan codes are reported this way: 0xXX (e.g. 0xB2)

keymaps in
/usr/include/linux/input.h
are reported in (seems to be) decimal format. (e.g. #define KEY_WWW 150 /* AL Internet Browser */)

They seem to be unrelated, what's the link between them?

/lib/udev/rules.d/95-keymap.rules maps DMI information (vendor/product
names) to keymap names.

Neither of those are in the udev rules, so we just need a new rule.

Can you please send the DMI information for the Aspire?

Thanks!

Indeed they have nothing to do with each other. scan codes are
hardware dependent and just enumerate the hardware keys. key codes
define a semantics for a particular key and provide an identifier for
them. The kernel and udev has to keep mappings from scan codes to key
codes on a per-machine basis.

Well, all the other Acers have reasonable product IDs, so I just
assume "Aspire 1640" will be correct. Please yell if not.

Simona, could you please run the two above and report the output here please?

@Martin.
I found out that other two keys are broken.

1) scan code: 0xEE key code: brightnessup

it's the lock screen key and it should be addressed to
#define KEY_COFFEE 152 /* AL Terminal Lock/Screensaver */

2) scan code: 0xF5 key code: presentation

#define KEY_PRESENTATION 0x1a9 /* AL Presentation App */

does nothing when clicked but it should open OpenOffice.org Presentation

This bug was fixed in the package udev - 151-6

---------------
udev (151-6) lucid; urgency=low

  * Merge some fixes from GIT HEAD:
    - key release quirk for Fujitsu Amilo 1848+u (LP: #530089)
    - key release quirk for Samsung Q210/P210 (LP: #530093)
    - key maps for Acer TravelMate 6593G and Acer Aspire 1640 (LP: #536914)
    - Decrease buffer size when advancing past NUL byte, to fix a buffer
      overflow the buffer if space is tight.
    - udev-acl: Correctly handle ENV{ACL_MANAGE}==0
    - input_id: Fix linking
    - firmware: fix possible segfault when firmware device goes away while
      loading
    - Fix switching Logitech bluetooth adapters into HCI mode. (LP: #444420)
    - cdrom_id: Open non-mounted optical media with O_EXCL. This should
      prevent confusing drives during CD burning sessions.

1) scan code: 0xEE key code: brightnessup

it's the lock screen key and it should be addressed to
#define KEY_COFFEE 152 /* AL Terminal Lock/Screensaver */

Reopening for this, committed upstream: http://git.kernel.org/?p=linux/hotplug/udev.git;a=commitdiff;h=43d0824

2) scan code: 0xF5 key code: presentation

#define KEY_PRESENTATION 0x1a9 /* AL Presentation App */

does nothing when clicked but it should open OpenOffice.org Presentation

That's known. X.org does not get along with key codes > 255 unfortunately, so you can only use these keys with non-X programs (e. g. LIRC).

1) "Fn+F2" hotkey should open help but it doesn't.

scan code: 0xA5 key code: help

Should be addressed to:
#define KEY_HELP 138 /* AL Integrated Help Center */

2) There is a Sync key.
scan code: 0xF9 key code: f23

Where could it be addressed? Ubuntu One sync? Gnome-pilot?

3) In this keyboard there are also two specific keys (not hotkeys) for Euro and Dollar.

scan code: 0xB3 key code: euro

scan code: 0xB4 key code: dollar

They should be addressed to
#define KEY_EURO 0x1b3
#define KEY_DOLLAR 0x1b2

respectively, but they are > 255 so I think we can do nothing.

But I have a question about this.
In this keyboard there is another Euro symbol under the "E" letter. It works with "AltGr+E".
Why this can be correctly addressed? Is there anything we can do for the keys above (Euro and Dollar symbols)?

Sergio,

all of those three (help, euro, dollar) are already correct on your system (http://launchpadlibrarian.net/41837474/orig-map.txt), so no need to change the udev rules further to get correct key codes. GNOME etc. would need to be fixed to actually react to those keys. You should be able to assign them to something useful in the keyboard shortcuts control-center applet.

Martin, thanks for your explanation.
Do you have any hint about the package to address to have them assigned permanently?
In this way I can open a new bug about the issue,

That's all. I reported all I could. Simona told me his laptop is broken, so you can go on.

BTW: Any hint about 2) (sync) too? It's the same as help, euro, dollar?

Thank you very much.

gnome-settings-daemon is a good general fallback. For some keys there
are specialized packages (like gnome-power-manager), but that can be
discussed in the bug.

> BTW: Any hint about 2) (sync) too? It's the same as help, euro, dollar?

It is assigned to "F23", so you can assign it to a custom launcher in
the keyboard prefs if you want. We won't do a default assignment of
this, though, since "F23" does not have a specific semantics.

Ok, thanks for the explanation.
I think it's ok now.

You can go through now.
