Hi there , this is my first time using MATE and im so happy i switch over here,but i have some problems, my laptops its an alienware 15r1 and im not getting any sound from the headphone jack, i have also installed an applet to switch the graphics but the icon its to big no matter what i try i cant seem to change the size of it, cant install spotify from the software boutique. One more thing its that in display options i can switch to 120hz on my laptop panel, i havent done it cause im scare i may break it, i couldnt switch to 120hz in windows , thanks a lot
