I have an emachine EL1850, with Intel Series 4 graphics onboard, it is set to 1280x1024 and it is too small for my eyes, I need to reset it to a larger size, when I do it shows only half a screen, as the top half is black, it did work one time at 1152x864 which was great. when I shut it down I cannot get it to resize again, very frustrating. Can anyone point me in the right direction. Maybe I might have to go back to 10.04 which worked great
