I have Imac G5 Power PC with nvidia geforce.
I run Lubuntu 14 live cd on it and everything was great - no problems so i decided to install this distrybution on my imac. After installation, there is a problem with display screen. After screen with Lubuntu logo, white screen appear with black horizontal lines and nothing more. But i can still run live version from dvd and its working with no problem. How can i fix this problem
