xmodmap settings are voided after a sleep

[Nick Rowan]

I use Macbook Air. To switch Command and Control buttons, I created ~/.Xmodmap and added the following command to the startup applications list:

xmodmap /home/nnrowan/.Xmodmap

This works fine until I close my laptop's lid and open it again. After waking up, my xmodmap settings do not work anymore. More importantly, it does not happen every time. Longer sleeps seem to be more likely to affect the settings of xmodmap.

Here is the contents of .Xmodmap:

clear control
clear mod4

keycode 105 =
keycode 206 =

keycode 133 = Control_L NoSymbol Control_L
keycode 134 = Control_R NoSymbol Control_R
keycode 37 = Super_L NoSymbol Super_L

add control = Control_L
add control = Control_R
add mod4 = Super_L
