Hello, I xkeyboard-config 2.6--2.10, the fr(oss) layout use the level5(rctrl_switch) option for some [...] reason. With this right control is quite useless. It seems to be related to the nbsp character but I can get it with AltGr+Shift+Space. This can be disabled by commeting out the level5(rctrl_switch) option in /usr/share/X11/xkb/symbols/fr. -- Gabriel
