TrackPoint Scroll

This works for my Lenovo ThinkPad R61 (7732-CTO) running Archlinux.

Create a file in /etc/hal/fdi/policy called mouse-wheel.fdi with the following:

<match key="info.product" string="TPPS/2 IBM TrackPoint">>
<merge key="input.x11_options.EmulateWheel" type="string">>true</merge>>
<merge key="input.x11_options.EmulateWheelButton" type="string">>2</merge>>
<merge key="input.x11_options.YAxisMapping" type="string">>4 5</merge>>
<merge key="input.x11_options.XAxisMapping" type="string">>6 7</merge>>
<merge key="input.x11_options.Emulate3Buttons" type="string">>true</merge>>
<merge key="input.x11_options.EmulateWheelTimeout" type="string">>200</merge>>
</match>>

Kindly ignore the duplicate tags.

Now, if you click and hold the middle mouse button, you can use the TrackPoint to scroll vertically and horizontally. As of June 8, 2009, I am still unable to get my touchpad to work ><

ksh PS1 and reloading .profile

OpenBSD comes with a plain "$" prompt in the shell. To spice things up, enter the following in your .profile:

PS1="\u@\h:\w$ "; export PS1

This will give username@host:PWD$.

---

To reload the .profile after making these changes, type the following:

. $HOME/.profile

There is a space after the first dot. Source

Importance of reading manual pages (wireless)

I had some difficulty configuring wireless at Georgia Tech for OpenBSD, but it was only because of my failure to read the manual pages carefully.

Under the nwkey entry of ifconfig(8), "The key can either be a string, a series of hexadecimal digits (preceded by '0x')..." (emphasis mine). Obviously, if there is no '0x', then ifconfig assumes your WEP key is a string. In our school's case, the WEP key is hexadecimal.

VIm and Arrow Keys

For some reason, using arrow keys in VIm is equivalent to typing ABCD. A temporary fix is to type :set term=cons25.
