Xmodmap struggles

Xmodmap struggles

[rusi]

Trying to change Alt key behavior
On a friends machine
$ xmodmap .Xmodmap

works but on mine I get

X Error of failed request:  BadValue (integer parameter out of range
for operation)
  Major opcode of failed request:  118 (X_SetModifierMapping)
  Value in failed request:  0x17
  Serial number of failed request:  15
  Current serial number in output stream:  15

The .Xmodmap is

clear mod1
keycode 0x70 = Alt_R
keycode 0x40 = Super_R
add mod1 = Super_R
add mod3 = Alt_R


(His ubuntu mine debian)

Context:
Trying to get apl running in xemacs

Try running xev on your machine. I suspect the keycodes are different on
the two machines, and you're using the wrong ones for your keyboard.

Try the sawfish window manager. It's extensible and written in cl and is emacs buddy. Great keyboard control.

Yep, been there done that, etc.

xmodmap -pm
xmodmap -pk
and
xev

are the main tools used to conquer keymap issues.
Grep along with xmodmap helps too.

In the OPs case, he had a clear for one modifier and
not the other.  One of the things to investigate.

Of course, this is not a gnu emacs issue so sorry
about that...
