Dell desktop, Logitech wireless keyboard, Ubuntu 11.10.

Yesterday my right and left control keys got (re/un)mapped, but I'm not sure by what. Now, whenever I press either one, a red "pulsating" red circle flashes under the pointer and then returns to normal. In Ubuntu this is the only sign that something has changed. However, in Virtualbox with a Windows guest, nothing that uses the control key will work. I'm not sure what changed it or where to look for how to change it back.

Same thing happened to me. Although I didn't change anything somehow my mouse settings changed.

You have to go to System Settings -> Mouse and Touchpad -> uncheck Show position of pointer when the control key is pressed. That should do it.

unfortunately in 13.04 that flashing pointer option is no longer available in the Trackpad/Mouse settings (or I'm bling and can't find it). so my setting is permanently turned on until I can find it in gconf. – hobs Aug 24 '13 at 15:35
