Comment 5 for bug 309434

I also think the duplicate status *may* be wrong. Whereas #289781 describes a solution of running setxkbmap after resume, this wouldn't work to fix this bug.

In this case, the keyboard mappings are lost every time the external keyboard is unplugged, so running it after resume won't guarantee proper functioning of the keyboard throughout the execution of the application, since a future disconnect of the external keyboard will bring the issue back.

This ticket (309434) is the only one that clearly describes what the issue really is.

BTW, I'm using a wireless keyboard, which means that every time that my keyboard loses connection even for a split second with its base, it resets my keyboardmap, making this the most annoying ubuntu bug I've come across, and a very important bug one to be fixed for any users of wireless keyboards with custom mappings.

Thanks for your time,
Marcos
