I have a new Dell E5580 machine running fvwm 2.6.5. I run it both with a logitech K810 keyboard and with Dell’s regular keyboard. Without modification,in order to get the function keys to work on the K810, you have to press the Fn button as well as the function key.
To make the logitech function keys work like they would on a normal keyboard (i.e., without hitting the Fn key), you have to do quite a bit of stuff as described in
http://www.trial-n-error.de/posts/2012/12/31/logitech-k810-keyboard-configurator.
Suddenly, this morning none of my keybindings would work from the default keyboard (with one exception), but all work fine with the Logitech keyboard (after following the steps described in the above link). For example:
Key F10 A MS Maximize 100 100
doesn’t work. The binding that does still work as expected is
Key F5 W A RaiseLower
On the other hand, the dell keyboard has now adopted the default behavior of the Logitech keyboard (except for F5)! To make F10 maximize the window using the default keyboard you now have to type Fn F10. It’s as if the modifications defined in the url have interacted with the fvwm software somehow.
Here are the three programs that do the work described in the above url:
/etc/udev/rules.d/00-k810.rules: (I’ve tried removing this file but the problem persists)
