I was trying to install Ubuntu 14.10 from DVD on my machine where before i always had windows.
CPU AMD Vision quad Core 16 gb ram AMD 7000 Series Graphic chipset
Created partition and set up boot with DVD-ROM, a black-purple screen appeared. Just logo is shown for few seconds before screen shut down and all it's impossible to use. Looking for a solution it seems a problem of compatibility with AMD graphic chipset. I found this solution: http://askubuntu.com/questions/162075/my-computer-boots-to-a-black-screen-what-options-do-i-have-to-fix-it
Not without checking the DVD integrity before, i started following the above instructions and this time something seemed were happening... Ubuntu 14.10 was loading the installation but at some point the background became totally black when the loading was still happening. In another couple of seconds the screen turned off and computer looked shutted down as written before. I tried to install Fedora and installation doesn't start (same problem described above). Debian instead has successfully completed the installation but at the first start, screen turns totally black with the cursor flashing, as i should had to write something. Trying with Ubuntu 12 the result is the same as for 14.
Anybody may help me please?
