Logitech K120

English Hardware
1

The Logitech K120 keyboard is a bare-bones wired keyboard which appears to be supported by Linux kernel 2.6+ (according to their website), yet is not recognized in Tumbleweed. The only reason I purchased this keyboard is to ensure I have something during my builds/setups, so I’m a little disappointed that such a basic device isn’t recognized but such a sweet, sweet distribution.

I have a number of Logitech devices now that don’t seem to be supported for whatever reason (M720 Triathlon mouse & N305 numberpad) and I’m looking to change that.

I know the basics of C and figure this is something I should really know how to do by now, but don’t know where to start. Can anyone point me in the right direction for the basics of building device drivers for openSUSE?

Much appreciated.

i really do not want to seem like i am hijacking the thread here, but just a question … are these devices USB and plugged into a hub? … if so I am having issues since just say this past Wednesday or so where any input device i try that is plugged into any hub i have, get’s seen (lsbusb and dmesg) but doesn’t function … plugged directly into the laptop and it works fine.

Anyway if this is not the case here, I will not post again … just felt like asking as your devices “may be compatible” but you are experience a bug that myself and one other person is seeing with Tumbleweed in the past few days

@drewbags:

Please take a look at this list: <https://www.freedesktop.org/wiki/Software/XKeyboardConfig/ModelsCompatibility/>.

  • Logitech Generic Keyboard
  • Logitech Ultra-X Keyboard
  • Logitech Access Keyboard
  • …

You then setup in “/etc/X11/xorg.conf.d/00-keyboard.conf” by calling “localectl” «with the user “root”»:


 > localectl list-keymaps     – to determine the available key maps – choose the one suited to where you are on this planet …
 # localectl set-x11-keymap «*keyboard mapping*» logitech_base nodeadkeys terminate:ctrl_alt_bksp

I’ve chosen the Logitech Model “logitech_base” for this example – the variant “nodeadkeys” may or, may not, apply for your case – please see the “xkeyboard-config” man page to determine if, your keyboard mapping needs the “nodeadkeys” variant or, not …

Interesting…** logitech_base** isn’t showing up in the man pages on either of my Tumbleweed machines.

Setting the keymap through localectl still edits the xorg.conf.d file successfully though, as I now see:


Section "InputClass"
   Identifier "system-keyboard"
   MatchIsKeyboard "on"
   Option "XkbLayout" "us"
   Option "XkbModel" "logitech_base"
   Option "XkbVariant" "terminate:ctrl_alt_bksp"
EndSection

No success unfortunately.

With a CLI and the user “root”, execute “mandb” a couple of times to rebuild the “man” database.
