I solved the problem by commenting on a line in /etc/X11/xorg.conf : Option "XkbVariant" "oss"
Section "InputDevice" Identifier "Generic Keyboard" Driver "kbd" Option "CoreKeyboard" Option "XkbRules" "xorg" Option "XkbModel" "pc105" Option "XkbLayout" "fr" # Option "XkbVariant" "oss" EndSection
Then I made slim system\quit\disconnect And since the problem disappeared in codeblocks I am satisfied!!!
