Thanks to the Arch forum i found that site:
DDvorak

And i was convinced in a very short time.
I need to learn the dovrak layout, especially the programmers
dvorak layout. Some years ago i switched from the german keyboard
layout to the english one cause typing ALT-GR + 8 is a real
pain, and this is what you gotta do to type a “[" with a german
layout.

But i was not that satisfied, until i found the idea of ddvorak.

After some trial and error i got thrown back. The ddvorak layout
is not implemented in Linux yet.

So i tried to remap everything with xmodmap, but no luck.
I mean i was successfull until i came to the dead key ',' which
i couldn't get working, no matter what i tried.
Whereas the dead key ',' is a very important one in the
DDvorak Layout.

Like i said, after some hours i was tired of fiddeling around
and i decided to use the Programmers Dvorak Layout which should
be part of every Linux installation that is a bit newer.
You can load that layout with:

setxkbmap -model pc104 -layout us -variant dvp

But thats only first part.
One thing i found out was really useful was the backspace
function at the 'b' key. Believe me, it feels like enlightement
if you dont have to break your right hand to delete some
characters. So i remapped the standard dvorak programmers
layout in the "us" file of
/usr/share/X11/xkb/symbols

(Other distros may have the file somewhere else)

This is the part that i changed:

partial alphanumeric_keys
xkb_symbols "dvp" {
...
key { [ apostrophe, quotedbl ] };
key { [ q, Q ] };
key { [ j, J ] };
key { [ k, K ] };
key { [ x, X ] };
//key { [ Backspace ] };
key { [ b, B ] };
key { [ m, M ] };
key { [ w, W ] };
key { [ v, V ] };
key { [ z, Z ] };
}

This means i moved all the keys of the down left
row one position to left.
I didnt find out how to map Backspace functionality
to the ‘b’ key in that us file.

After some research i came back to xmodmap.

Here is my current .xmodmap:

keycode 56 = BackSpace
keycode 9 = Caps_Lock
keycode 66 = Escape

clear Lock
add Lock = Caps_Lock

This means:
1. Map the Backspace functionality to keycode 56, which
is the ‘b’ key on my keyboard.
Which is fu***** handy.

The Rest remaps the Escape and Caps Lock function.
I am doing a lot of writing in gvim.
(gvim >>>>> All)
Everybody who uses gvim a lot knows that getting
to command mode breaks up the left Hand.

So i took the idea from the ddvorak man and thought.
Hey, i rarely never use that goddamm Caps_Lock key which
is in a very close position to the left Hand.

To make a long story short.
Line 2 remaps the Caps_Lock function to my ‘Esc’ Key.
Line 3 remaps the Escape function to my ‘Caps Lock’ Key.

Line 4 and 5 are needed for whatever, i know remapping
Caps Lock wont work without them.
Ask google for more information.
