Public bug reported:
I have a Sony Vaio VGN-FW250J laptop and the hotkey for suspending (FN +
F12) is mapped as brightness up instead. I followed the instructions on
Ubuntu wiki for troubleshooting hotkeys and found out with the help of
"evtest" that the hotkey is recognized as "Event code 225
(KEY_BRIGHTNESSUP)" instead of "Event code 205 (KEY_SUSPEND)". I have
pasted the evtest report below. This has persisted for several Ubuntu
version (, but I failed to report it until now because of
procrastination).
Input driver version is 1.0.1
Input device ID: bus 0x10 vendor 0x104d product 0x0 version 0x0
