[Bug 939868] Re: Sony VPCEL2S1E, some hotkeys not working

[Thomas B Homburg]

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")

Title:
  Sony VPCEL2S1E, some hotkeys not working

Status in “udev” package in Ubuntu:
  Confirmed

Bug description:
  Trying with Ubuntu Daily 12.04 (20/2/2012),

  Hotkey Fn+F1 (disable touchpad): Not working
  Hotkey Fn+F2 (mute/unmute sound): Working
  Hotkey Fn+F3/F4 (audio lower/higher): Working
  Hotkey Fn+F5/F6 (brightness lower/higher): works, but also invokes the "enable/disable external monitor" (also changes resolution?)
  Hotkey Fn+F7 (enable/disable external monitor): works but also appears to change resolution (using with HDMI)
  Hotkey Fn+F12 (hibernate): Works fine (with open-source graphics driver, hangs if FGLRX is used)
