Re: Inspiron 531 screen not working/freezing
This might be a bug in the default video driver. Your graphics card is an Nvidia 6000 series, isn't it? If you're using Ubuntu 13.04 you could try 12.04, or vice-versa. Otherwise you could create an Xorg.conf and then edit it so it uses a different driver, like "fbdev" or "nouveaufb" instead of "nouveau":

Edit it: sudo nano /etc/X11/xorg.conf
(find where it says "driver" and change that to whatever you want to try)
Exit Nano by pressing Control-X, Y and Enter.
return to GUI: sudo start lightdm
That should give you enough of a desktop to find your way clear to installing a proprietary Nvidia driver, if there are still any available for that series of card.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
