Solved - Ubuntu Right-Alt key doesn't work

Posted by JD 02/18/2009 at 15:34

For the last few years, every time after loading Ubuntu, I discover that my right key doesn’t work correctly anymore. It is an internationalization thing.

To fix this:
Comment out in the /etc/X11/xorg.conf:
Option “XkbOptions” “lv3:ralt_switch”

Restart your X server. Life is good.
This should be applicable to any Linux system running X/Windows. The “lv3:ralt_switch” is used to enter international characters as needed in Spanish accents, German umlauts, and other language characters. If you don’t use these characters outside a word processor, then this setting is bothersome.
