View Full Version : [ubuntu] HELP: reinstall ubuntu screen problem

November 13th, 2012, 05:11 PM
Hi all;

First I want to say that I tried everything I could find on the web,
but I did not managed to get a solution so here I ask you for help:

I have a laptop (lenovo g560) with dual-boot win7, ubuntu.
Two months ago the monitor screen became really too bright
(barely given anything to see) after a force restart in ubuntu
(the problem was in BIOS, win7, and ubuntu).

I upgrade version of ubuntu from 12.04 to 12.10 and the problem solved
itself. Everything was great until a week or two but now it appeared
again the entire screen is full of lines and I can not see anything on it.
(BIOS, win7, ubuntu again). I tried everything ..

I tried to reinstall ubuntu but I just can not set external monitor
as the main one, I tried unplugging the screen of the laptop from the
motherboard, but the external monitor turn's only on when I'm going
to win or ubuntu. I really have no more ideas, so if you have any
ideas please help.
