I have just upgraded from Fedora 14 with Gnome desktop to Fedora 20 withMate desktop.  Under F14, I previously swapped CapsLock with Control_Left,and Alt_Right with Control_Right.  These I did by adding the following linesto /etc/X11/xinit/xinitrc-common  (excuse the 'xmodmap's on each line)xmodmap -e 'clear lock'xmodmap -e 'clear control'xmodmap -e 'remove mod1 = Alt_R'xmodmap -e 'add control = Caps_Lock Alt_R'xmodmap -e 'add mod1 = Control_R'xmodmap -e 'add lock = Control_L'Under F14, they work as expected.  However, when I copy these to/etc/X11/xinitrc-common under F20, the CapsLock Control_L swap does nothappen.  Instead, both keys become CapsLock.  The Alt_R/Control_R swap doeswork correctly.  Next, I tried the solution offered in the xmodmap man page, and also here:Remapping Caps Lock with xmodmap doesn't workxmodmap -e 'remove Lock = Caps_Lock'xmodmap -e 'remove Control = Control_L'xmodmap -e 'keysym Control_L = Caps_Lock'xmodmap -e 'keysym Caps_Lock = Control_L'xmodmap -e 'add Lock = Caps_Lock'xmodmap -e 'add Control = Control_L'Strangely, CapsLock and Control_L keys are now both Control_L.Doing all swaps with keycode mappings works like a charm though:xmodmap -e 'clear Lock'xmodmap -e 'clear Control'xmodmap -e 'remove Mod1 = Alt_R'xmodmap -e 'keycode 66 = Control_L'xmodmap -e 'keycode 37 = Caps_Lock'xmodmap -e 'keycode 108 = Control_R'xmodmap -e 'keycode 105 = Alt_R'xmodmap -e 'add Lock = Caps_Lock'xmodmap -e 'add Control = Control_L Control_R'xmodmap -e 'add Mod1 = Alt_R'The original keycodes before the swap are 66=CapsLock, 37=Control_L, 108=Alt_R,105=Control_R.  I would like to understand why the first two methods would not work.  Anyideas?
Swap CapsLock and Control using xmodmap (man page solution does not work)
