On Linux systems, this key has no effect at all since most desktop enviroments don't deal with KEY_DISPLAY_OFF. By mapping it to KEY_SCREENLOCK instead, would enable desktop environments to handle this key as a screen lock intent from the user, out of the box.

The fact that current desktop environments do not handle this key is not a reason to change kernel behavior. If screen lock is simply your preference then you can change the mapping via udev on your system without the need to patch the kernel.

Hi Dmitry, I've picked up this particular key event because it would trigger a close behavior to the one seen on Windows. It is far from being my preference, which would be an exact mimic of the Windows behavior (and can be achieved by xset dpms force on/off from user space). The idea of this patch is to improve the user experience, by giving that key a behavior as close as possible to what users might experience on Windows. Because most Linux desktop environments also turn the display off after locking the screen, this would be a good approximation to what happens on Windows. I think it is more about giving (consistent) behavior to it than changing it. I agree it is possible to control that via udev or something else. But most regular users won't be able to do that, ending up with an unused key, though. The hardcore user that would prefer a very different key behavior could keep using udev to do that. So IMHO I think that setting this up on the kernel would be a good approach in this case. Thanks. Vinícius ^ permalink raw reply [flat|nested] 9+ messages in thread

I am sorry, I disagree. I understand that patching the kernel might be easier than implementing new shortcut/behavior in various desktop environments, but that does not make it the right approach.
