Disabling Super key?

[Girish Kulkarni]

Is there any way I could disable the Windows key on my keyboard?

I use FreeBSD 7.0-RELEASE on a Dell Inspiron 640m laptop. My Windows
key ("Super_L") has developed a problem for some unknown reason: it
gets pressed and remains so without my touching it. I could diagnose
this only using xev, which reported a constant Super_L KeyPress event.

This means that I cannot enter text in for example Firefox or Emacs
most of the time and this is terribly irritating. I could probably
solve the problem by disabling the Super key.

Thanks,
Girish.

Did you try kbdcontrol ?

Thanks. I could do that using kbdcontrol(1) although this disables the
Windows key only in the console and not in X, where xmodmap(1) does
the job instead. I could make the effect of kbdcontrol permanent by
adding a line to ~/.bash_profile. Any idea how I could make the effect
xmodmap permanent? (Adding relevant lines to ~/.xsession doesn't seem
to help.)

Make a ~/.xmodmaprc with your setting(s) in it and then call it from
~/.xsession or ~/.xinitrc (depends on how you start X). E.g you want a
line like:

xmodmap -display :0.0 .xmodmaprc

in there.

For the kbdcontrol stuff, I put it in /etc/rc.local

Thanks for your reply. This doesn't seem to be helping though. I use
~/.xsession to start X so I put the following two lines in it:

xmodmap -e 'clear mod4'
xmodmap ~/.xmodmaprc

where ~/.xmodmaprc contains relevant instructions for disabling the
Super key. I found that the Super key was not disabled even after
this. I also tried including these two lines in ~/.xinitrc.

First, you should check what keycode the key you want to disable
produces. You can check this by using X11/xev and pressing the key.

On my English PC keyboard, the left Windows key produces keycode 115.

I can disable it by putting the following line in ~/.xinitrc since I
use startx(1):

xmodmap -e "keycode 115="

If you use xdm(1) or similar display manager, then you want to put
that line in ~/.xsession

Don't worry about having an xmodmaprc.

You'll obviously need to restart X for the change to take effect. Or
just run it from a prompt for it to have an immediate effect.

An option to have all settings in one file (traditionally the
~/.xinirc file) is to create a ~/.xsession file with these three
lines:

#!/bin/csh
source ~/.cshrc
exec ~/.xinitrc

Then, your ~/.xinitrc can contain any xmodmap call you want,
for exmaple:

xmodmap ~/.xmodmaprc

So you don't run into trouble where to configure your X session.

After all that advice, one last piece remains - buy another keyboard;-)
