Keyboard

In KDE: Keyboard model = IBM Thinkpad 560Z/600/600E/A22E, Intl.

In ~/.Xmodmap:

! from http://stefan.desire.ch/howto/x41debian/
keycode 77 = Num_Lock
keycode 233 = XF86Forward
keycode 234 = XF86Back

! from the Internet: use right control key as Windoze-Key
remove Control = Control_R
keycode 109 = Super_R

And in ~/.Xsession:

#!/bin/sh
xmodmap ~/.Xmodmap

For some unknow reason, kdm/KDE does not execute ~/.Xsession, therefore:

cd ~/.kde/Autostart && ln -s ~/.Xsession dot.Xsession

I use the Super_R key (a.k.a. Windoze key) amongst other things as follows (see KDE Keyboard Shortcuts):

• Win-X = Maximise window
• Win-H = Maxmimise horizontally
• Win-V = Maxmimise vertically
• Win-Z = Minimise window

Real men don’t click..

3d Acceleration

If you want 3d acceleration working well (e.g. for Google Earth), you’ll need the new Intel driver (http://www.intellinuxgraphics.org). Fortunately, ''Jö'' provides updated packages for etch:

In /etc/apt/sources.list:

{{{deb http://jorrit.de/debian etch main}}}

And in /etc/X11/xorg.conf:

Section "Device"
        Identifier      "grafiktschipp"
        Driver          "intel"
EndSection

apt keys for 3rd party repositories

~/bin/apt-add-key:

#!/bin/sh

for X in $*; do
  gpg --keyserver wwwkeys.eu.pgp.net --recv-key $K; gpg -a --export $K | apt-key add
done
