A fix that works for me: Add/change a line: Option "XkbVariant" "intl"
to your `/etc/X11/xorg.conf.d/10-evdev.conf` Section "InputClass" Identifier "evdev keyboard catchall" MatchIsKeyboard "on" MatchDevicePath "/dev/input/event*" Driver "evdev" Option "XkbModel" "asus_laptop" Option "XkbVariant" "intl" Option "XkbLayout" "us" EndSection -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1016996 Title: Right ALT key mapped through .Xmodmap does not work in Firefox Status in “firefox” package in Ubuntu: Confirmed Bug description: I have mapped the Right Alt key (keycode 108) and the Right Winkey (keycode 134) through .Xmodmap as follows: d@lexx:~$ cat .Xmodmap keycode 108 = ediaeresis Ediaeresis keycode 134 = ccedilla Ccedilla However, only the Right winkey works as expected producing the çÇ characters in Firefox. The Alt key does not work (no character gets entered in text fields in Firefox). The Alt key as it is mapped works in other applications such as Konsole, Konqueror, etc., producing the characters ëË. The exact same setup was working in prior versions of Kubuntu and Firefox, but it does not work in Kubuntu 12.04 LTS.
