I would like to use the key AltGr as my main Alt key. Unfortunately, the AltGr doesn't behave like the left Alt key with the software I use, e.g. urxvt.

With the command xev the left Alt key has the keycode 64, and the AltGr has the keycode 108.

$ xmodmap -pke gives me the following result for the left Alt key and the right AltGr keys:

keycode  64 = Alt_L Meta_L Alt_L Meta_L
keycode 108 = ISO_Level3_Shift NoSymbol ISO_Level3_Shift

To be brief, I would like to swap the left Alt key, with the AltGr key.

I'm using 14.04 server.

Found the solution by myself :-)

$ xmodmap .Xmodmap

The .Xmodmap file should contain the following:

! Swap Mod1 and Mod5
!
remove Mod1 = Alt_L Meta_L Alt_L Meta_L
remove Mod5 = ISO_Level3_Shift NoSymbol ISO_Level3_Shift
keysym Alt_L Meta_L Alt_L Meta_L = ISO_Level3_Shift NoSymbol ISO_Level3_Shift
keysym ISO_Level3_Shift NoSymbol ISO_Level3_Shift = Alt_L Meta_L Alt_L Meta_L
add Mod1 = Alt_L Meta_L
add Mod5 = ISO_Level3_Shif
