When I try to move keys, so that I have CapsLock on escape, Control on CapsLock and Escape on left control, I get the following error:

% xmodmap ~/.Xmodmap
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

That is the code that fails:

remove Lock = Caps_Lock

! ESC
keycode 9 = Caps_Lock
add Lock = Caps_Lock
remove Control = Control_L

! CapsLock
keycode 66 = Control_L
add control = Control_L

! Control_R
keycode 37 = Escape

! 2*Meta_L
keycode 148 = Meta_L
add mod1 = Meta_L

If I comment out all lines that start with either add or remove it runs without any errors, but does not do what I want.

Program versions (Gentoo x86 (stable)):

• xorg-server-1.7.6
• xmodmap-1.0.4
• xf86-input-evdev-2.3.2
