No worries, thats might happen for everyone. Some good news, now there is some reaction on both keys in dmesg:
[ 28.599434] (efault) data 0x0:0x00x0 Message is the same for Fn+F4 and Fn+F10. Mouse still work in weird way with mouse wheel not working. There is also a quirk that restart entry in gnome-shell reacts only on right click, left-clicking makes menu disappear. ** Attachment added: "dmesg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1927545/+attachment/5504727/+files/dmesg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927545 Title: Some of Lenovo Lenovo Essential Wireless Keyboard Fn keys doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1927545/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
