Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I've created ubuntu 12.10 bootable usb key with lili, after booting from it when i selected install some command lines appear and than screen lights off, but i realised that laptop was not off..

So i install ubuntu (i was using torch to read information on screen, expecting everithing would be ok) but after finishing installation and reboot nothing has changed.

Ubuntu is loading but screen lights is off. Only some shades appear. Screen lights during boot but off as ubuntu is loaded...

Hi vitali, please see the faq and meta for some guidelines on asking questions. This is a bit hard to understand. – belacqua Nov 20 '12 at 0:06
Did you try changing the brightness from the keyboard? – Erik Konstantopoulos Jun 20 '13 at 11:19
