When i press any multimidia key from touch-sensitivity from my laptop lenovo z470, the indicator of my ubuntu 11.10 dont work any more.
I found palliative solution, pressing Ctrl Alt F1 and returning to the grphical interface with Ctrl Alt F7 or suspending closing the notebook and returning from suspending.
I search in logs, and try monitoring key code with xev, wihtout sucess.
Thanl you for any help.
