Comment 22 for bug 1386111

For me since recently (I don't know since when exactly because I do not use this laptop a lot) a bunch of system shortcuts (System settings > Keyboard > Shortcuts) stopped working on an Acer C720 (running Ubuntu 15.04).

Some shortcuts do now work for me. I have, for example SHIFT+F7 to increase display brightness, and ALT+CTRL+T to launch a terminal and SHIFT+BACKSPACE = DELETE. These don't work. Some others, like ALT+CTRL+Cursor keys to move between virtual desktops for example work fine.
