I have installed Lubuntu 11.10 for it's much lighter than Ubuntu itself with Unity, but I have serious problem. I need to put another keyboard layout- Bulgarian, but I simply can't do it. Tried a lot of things but can't figure out how to do it. Please help me for it's important. :) Thanks!
Assuming you want to use two keyboard layouts (US and Bulgarian) systemwide and switch between them using both shift keys, edit the default keyboard file:
sudo leafpad /etc/default/keyboard
Modify the file so it includes the following:
XKBMODEL="pc105" XKBLAYOUT="us,bg" XKBVARIANT="," XKBOPTIONS="grp:shifts_toggle,grp_led:scroll"
Save and exit. Now when you restart, you should be able to switch between the two layouts by hitting both shift keys at the same time. If you are using a different keyboard model or want to change layouts using a different key combination, you will have to modify the relevant line(s) in the example given above.
