view full story

http://ubuntuforums.org – Hi everyone Yesterday i tried to install Ubuntu on a friends' Laptop. (model 7715z, Acer) As i booted into the live cd i noticed the screen going black as it would normaly show the Ubuntu loading screen, after a few tries, i managed to get the screen working through entering the keys which manage her laptops brightness in a random manner (this might also work with other keys haven't tried it). As i did this, the terminal as usual showed the keycharacters as a response, after whitch it succesfully showed the live system. The above would be the first problem i'd like some help with. secon (Hardware)
