This model has laptop with two rows of buttons. Lower row doesn't work at all since I installed ubuntu. Before this, with Windows installed there was no problems. Upper row works for some time after waking up, then it stops reacting either at all, or works only in some of the opened programs, e.g. firefox, terminal, etc. If I close/open the lid, thus log out and log in, it works until I try to launch any new program, then usually stops reacting completely.
