Hm, Logitech keyboards are naughty. Your's identifies exactly like the Logitech Wave Cordless, but apparently has entirely different scancodes.
Can you please download the two attachments that I'll do, and install them with sudo cp 95-keymap.rules /lib/udev/rules.d/ sudo cp logitech-wave-cordless /lib/udev/keymaps then detach/reattach the keyboard and see if the "unknown scancode" errors disappeared? Please also check with /lib/udev/keymap -i <device> (find out the <device> with "findkeyboards") that the two keys now really produce "zoomin" and "zoomout". Thanks! ** Attachment added: "95-keymap.rules (for /lib/udev/rules.d/)" http://launchpadlibrarian.net/37010105/95-keymap.rules -- zoom-plus, zoom-minus keys not mapped correctly for logitech s510 keyboard https://bugs.launchpad.net/bugs/259244 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
