Bug Description

i have Acer TravelMate 2410, and i have 2 addition keys (euro and dolar) on my keyboard. that keys is not mapped.
keycode e033 is euro sign and
keycode e034 is dolar sign

additional i have 'fn' keys
fn+F4 = keycode e028 could sleep computer (it's showed on that key), but i doesn't (but it's mapped)
fn+F5 = keycode e029 should change video output (external CRT, LCD or both)

e033 - euro sign - just write E (no, not E, but euro sign :)
e034 - dolar sign - just write $
e026 - fn + F2 - Acer eSettings - i don't know what could be mapped to this
e027 - fn + F3 - Acer ePowerManagement
e029 - fn + F5 - Display toggle - switch display output (crt, lcd, lcd+crt) - throw i810switch
e071 and e072 - fn + F7 - Touchpad toggle - this is two state key. It sends e071 if touchpad is toggled, and e072 where it's turned off. Maybe nothing is needed to be mapped

Possible workaround for the Euro key:

Select: System - Preferences - Keyboard
      Select: 'Layout Options' tab
           Select: 'Adding the EuroSign to certain keys'
                 Select prefered key
           Select: 'Third level choosers'
                 Select prefered chooser key
now you should be able to use your chosen chooser key + chosen euro key to print the €.

This dosen't address the keymap issue but should allow users to easily type € when needed.

Matthew Lange (matthewlange) wrote :

Agreed, that workaround does work, using the Alt Char key and the key with the third-level euro sign on it. It still doesn't address the key map, no, but it does help with typing, as Daniel said.

I'd like to revisit Ondřej Nový's original post:

fn + F5 - Display toggle - switch display output (crt, lcd, lcd+crt) - throw i810switch

This key does not work for me either. Is there a known work-around? I'm happy with a terminal window command to toggle displays if it comes to it.

Paul Sladen (sladen) wrote :

malbery: could you open a separate report for your issue with the VGA toggling. This entry is about the € and $ special keys that showed up on one bunch of laptops and which we don't really have a generic answer to yet.

I have a similar problem, but I don't get any reaction from pressing the key euro and dollar keys. Neither showkey -u nor xev nor the GNOME keyboard shortcut mapper nor /var/log/acpid shows anything. So it seems I cannot even use xmodmap to do anything with these keys (which I would very much like to as the are where Home and End should be, really).

System info is:

$ sudo dmidecode -s system-manufacturer
Acer, inc.
$ sudo dmidecode -s system-product-name
TravelMate 8200
$ sudo dmidecode -s system-version
Not Applicable

Under Windows I am able to trap the keys using a keyboard hook DLL with the following code:

long __w64 __stdcall KeyboardHook( int code, WPARAM wParam, LPARAM lParam )

{

 if (HC_ACTION == code) {

  LPARAM scan = (lParam & 0x7F8000) >> 16;

  if (0 != scan) {

   // not simulated

   switch (lParam) {

    case 20119553: // euro symbol

     return simulate( VK_HOME, lParam );

    case 20185089: // dollar symbol

     return simulate( VK_END, lParam );

   }

  }

 }

 return CallNextHookEx( hookHnd, code, wParam, lParam );

}

Thanks for the tip! Unfortunately, the keys still show no reaction.

e033 is for euro

Great info! It does on mine too. So I'll look into this.

Unfortunately, this only takes half the way. Using setkeycodes I can
enable the keys for full screen terminals, but not for X. From "man
setkeycodes":

BUGS
       The keycodes of X have nothing to do with those of Linux. Unusual keys
       can be made visible under Linux, but not under X.

Any ideas for X anyone?

I wrote up a tutorial on how to get the € and $ working on a 5610. The scancodes are exactly the same, so you don't even need to change anything:
https://wiki.ubuntu.com/LaptopTestingTeam/AcerAspire5610#head-764d126e9802bf3204689a234b42048a2b0ffb0d
They're now working perfectly for me €$€$€$€$€$€$€$€$. Nothing special is required, they are recognized by the Feisty kernel. I'll move the section later.

Anyone interested may see https://bugs.launchpad.net/ubuntu/+source/hal-info/+bug/281951
where a solution was proposed for some of the Acer 5920 keys.

About € and $, (untested)
I think you may map them to some scancodes,
and then use loadkeys to map these scancodes to strings '€' and '$'.

On Ubuntu Jaunty, on my Acer Extensa 5620, the € and $ keys to the right and left of the up arrow key do report keycodes (435 for € and 434 for $) but they are non-functional in X. Xorg.0.log shows "(WW) AT Translated Set 2 keyboard: unable to handle keycode 435" and "(WW) AT Translated Set 2 keyboard: unable to handle keycode 434" when I press them.

Steve Langasek (vorlon) wrote :

These keys are mapped correctly in the kernel, but a limitation on the number of distinct keycodes that X can handle prevents these from being communicated to the X server.

To work around this, you can use setkeycodes to map the key to a keycode below 256 that you aren't using, then use xmodmap to map this keycode to the desired keysyms.

Hi,
I'm using Acer Aspire 5672WLMi laptop , I'm trying to get my $ and euro keys to work [both euro and $ keys are on either side of the Up arrow key ]

I tired to follow this wiki given on this bug report>
https://wiki.ubuntu.com/LaptopTestingTeam/AcerAspire5610#%E2%82%AC%20and%20$%20Keys
But stopped at the xkeycaps section , since *none* of the keyboard layouts did not match my laptop keyboards , and i didnt want to mess the layout , and didnt do anything further.

Now, the weird thing is the $ key triggers a ","
- earlier it did *not* trigger *anything* , previously the $ key just did not work[no output]

I ran $ xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p'
it returns:
$ > keycode 129 = (keysym 0xffac, KP_Separator), state = 0x0
euro > keycode 128 = (keysym 0x0, NoSymbol), state = 0x0

something seems to have changed but assigned wrongly, unfortunately i dont know the keycodes/keysym before i tried the wiki

seems my keycodes are *not* outside the keycode range but are not assigned properly...

this is not probably the same bug ! or maybe it is , since i dont know the previous keycodes :(
should i file a separate bug or does anyone know how to fix this?

I have this bug on an Acer Aspire 5315-2077. Is there a guide to mapping the keys somewhere?

I have an Acer Aspire 5930G and the same problem as Scott Barnes wrote on 2009-05-12:

why does x have this limitation and why are the keys mapped there?

I have an Acer aspire 4315 running Ubuntu 10.04.
By default showkeys -s doesn't report anything when the euro or dollar keys are pressed. As above, the default scancodes are >255. Using "evtest", I find that the scancodes are "b3" and "b4"

I have made these usable by
1) Adding to /etc/rc.local (and making sure it is excutable):
setkeycodes b3 183
setkeycodes b4 184

2) Creating ~/.Xmodmap with
keycode 183 = XF86Launch2
keycode 184 = XF86Launch3

Reboot. (Or sudo /etc/rc.local; sudo xmodmap ~/.Xmodmap)

Probably could map them to other directly usable things like euro symbol, home end etc as well

3) Myself, I now use these keys in System/Preferences/Keyboard Shortcuts, mapped to certain special functions.
