I just installed Ubuntu 12.04 (Pangolin) on the Macbook Pro that I got from work. The fact that Apple
rearranges the has a different bottom row of keys drives me nuts, though. The placement of the Command keys are where the Alt keys should be, and there is no right ctrl key. My muscle memory is trained for a standard keyboard and fighting it, especially while coding, slows me down a lot.
Luckily, there's a utility called xmodmap that will let you remap these keys however you want. Here's what we're going to do_
Drop the following code into a text editor and save it somewhere. I saved it as .xmodmappings in my home directory_
! ! clean most of the modifiers clear control clear mod4 clear mod1 ! ----------------- ! left side ! ---------------- ! keycode 64 is the left alt key keycode 64 = Super_L ! key code 133 is the left command key keycode 133 = Alt_L Meta_L ! ------------------ ! right side ! ------------------- ! key code 134 is the right command key keycode 134 = Alt_R Meta_R ! keycode 108 is the right alt key keycode 108 = Control_R add mod4 = Super_L add mod1 = Alt_L Meta_L add mod1 = Alt_R Meta_R add control = Control_L add control = Control_R
To test this, drop into a terminal and type
$ xmodmap ~/.xmodmappings</code>
It should make the following changes_ Left Alt -> Left Super Left Command -> Left Alt Right Command -> Right Alt Right Alt -> Right Ctrl
Now test it out. If everything looks kosher, you can set this to run every time by pulling down the gear/power menu from the taskbar, choosing "Startup Applications", and adding a new item containing the above command.
Note that this works on a 7th-gen Macbook, and the layouts may differ slightly on other models. If it doesn't work for you, running
xev from a terminal will let you discover the keycodes for your model, which you can substitute into the above script.
