Public bug reported: Recently I have noticed that Zoom In/Out slider on my Microsoft Ergonomic Keyboard 4000 stopped working. I tried investigating what's wrong and noticed that my keyboard reports as two different input devices according to evtest
sudo evtest output: (...) /dev/input/event2: Microsoft Natural® Ergonomic Keyboard 4000 /dev/input/event3: Microsoft Natural® Ergonomic Keyboard 4000 (...) /dev/input/event2 responds to normal keys /dev/input/event3 responds to multimedia keys and zoom in/out keys The most puzzling thing is that multimedia keys actually work and be bound. For example I have bound KEY_F17 to Next track in Amarok. Play/pause, Vol. Up/Down and Mute worked out of box. uname -a: Linux demonbane 3.16.0-55-generic #74~14.04.1-Ubuntu SMP Tue Nov 17 10:15:59 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux lsb_release -rd: Description: Ubuntu 14.04.3 LTS Release: 14.04 ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1523675 Title: Microsoft Ergonomic Keyboard 4000 has two input devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1523675/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
