Date: Tue, 02 Dec 2008 23:38:26 +0100 From: Couriersud Subject: Re: SDL: Keyboard layout unknown I have attached a diff which will add an additional keyboard layout to the x11 driver. The issue arose, when I moved to ubuntu intrepid. I was only able to map the keys available on my keyboard. The differences to the existing keyboard was the mapping of HOME,UP,DOWN and some other keys. Now only one issue remains. Dead keys (e.g. ^, ` ') on european keyboards do not generate a "scancode" event. Just a text event when the key is composed (e.g. ?? ?? ??).
