I have an Acer Aspire 1360 and half my screen is black, I cannot change my resolution because then my computer freezes. I am running the lastest Ubuntu and have tried anything any advice. I've also searched forums and many have this problem but couldn't find a fix and Ubuntu is impossible to use like this, any help would be appreciated.
Try restart lightdm:
after boot press: Ctrl+Alt+F3 (or another one)
then login and type:
Hope it helps. (it does for me: eee-pc 1101ha)
