Hi NG

In order to be able to use my mouse wheel, I am required to run this
command:

xmodmap -e "pointer = 1 2 3 6 7 4 5"

And have currently put this line in my /etc/rc.d/rc.local file, so that it
would be executed during startup, so I wouldn't need to run it manually
every time I boot (boot it every day), but when the command is executed
during startup, I get this reply:

xmodmap: unable to open display ''

Or "Can't connect to X server".

Does anyone know a way out of this problem ? If so, I am very greatful!

Kind regards,
Mads

The X display does not yet exist when rc.local is executed. Try putting the
xmodmap command in /etc/X11/xinit/xinitrc, or ~/.xinitrc, or ~/.xsession
(depending on how you start X) instead of rc.local. This way, the command
will run when X starts, and the "display" will exist.

What happens if, instead of that line, you put the appropriate lines
in your xorg.conf? The only reason I ask is that I spot the '4' and '5'
in your thingie - (BTW, I haven't looked up xmodmap yet, because I
haven't had to), which immediately pops up "ZAxisMapping" in my mind,
and you did mention 'wheel' - the math really isn't that hard.

Good Luck!

Take a look at some of the "official" ~/.xinitrc's (those created by
xwmconfig). The Right Way[tm] is to use
11/xinit/.Xmodmap for global settings and ~/.Xmodmap for user specific
settings.

Mine looks like this:

kb@clockwork:~$ cat ~/.Xmodmap
pointer = 1 2 3 6 7 4 5

It's for people with a 7-button-mouse who want to use the wheel *and*
the thumb buttons (which is usefull for browsing forward/backward with
mozilla, gaming, ...)
