(note that sleep / hibernate actions are usually still reported also throgh acpi, because some programs expect them to come from there, that would explaing your Fn-F1/sleep working) to test this, just run as root on the linux console (not in a termnal in X): showkey -s and then pres the keys (ie Fn-F4,) to stop showkeys, just don't press anything for 10 seconds... if you see numbers appearing after each keypress / release, then the key directly generates keyboard ivents and its possible you will see them directly in X, for that jus run (now under X) xev and (the window that appears must have focus / be active) press the keys again, xev will print the X keycodes/keysyms to its output... if you see reasonable names there, then you should be able to map those keys in the programs you are using (ie global hotkeys in kde, etc...) note however that qt/kde doesn't recognise some of the more exotic keysyms... (in my case XF86TouchpadToggle produced by Fn-F8 on thinkpads ;) if you can see the key in showkey -s but not in xev, the problem might be in kernel keyboard map (though i'm not sure if the x's evdev driver uses that) or in the evdev driver not mapping that key basically the kernel driver reports scan codes (what showkey -s shows), kernel translates that to keycodes (showkey -k to see them) and then X's input driver (ie evdev) translates those to the X keycodes X server again trasnlates them to keysym-s.... yoyo > > However, for vanilla-sources-3.2.9 the only key that is doing > anything seems to be Fn-F1 which says 'button/sleep' (using > acpi_listen) but actually just turns on the screen saver as best I can > tell. > > Note that even with 3.2.7 most keys don't actually work, but at > least they all produce acpi_listen events.
