Xmodmap works abnormally on Ubuntu14.04，the key mappings will be reset after a few minutes

[zyr]

I want to swap theses two keys: Caps_Lock and Control_L, my configuration file as follows:
~/.profile:
if [ -f "$HOME/.xmodmaprc" ]; then
xmodmap ~/.xmodmaprc
fi

~/.xmodmaprc :
remove Lock = Caps_Lock
remove Control = Control_L
keysym Control_L = Caps_Lock
keysym Caps_Lock = Control_L
add Lock = Caps_Lock
add Control = Control_L

The same configuration, On Ubuntu12.04, it worked properly. After the upgrade, it works abnormally, after a few minutes, the key mappings will be rest, I have to run 'xmodmap ~/.xmodmaprc' again and again.

I also use a virtual machine, and the key mapping changes can't map to the guest system, but ubuntu12.04 don't have this problem.

I am sure my configuration file “.xmodmaprc“ had not been “called” by other softs or system repeatedly.
