Hello I have the same problem on Sony VPCCB4C5E
I have created a patch with an udev rule and a specific keymap for my model I will submit this after reading /usr/share/doc/udev/README.keymap.txt.gz You may try: $ sudo /lib/udev/keymap input/eventX 0x05 f21 This should work for fn+f1 -> touchpad toggle To weird things: * "$ sudo keymap -i" writes scancodes + 7. So you have to subtract 7 to get the usable scan code: fn+f1: 0x0c -> 0x05 * KEY_TOUCHPAD_TOGGLE does nothing, you have to use KEY_F21 instead (hence "f21") -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/939868 Title: Sony VPCEL2S1E, some hotkeys not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/939868/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
