view story

http://ubuntuforums.org – Once ubuntu finished installing; after removing DVD and pressing enter when requested system never managed to shutdown properly in order to start POST just get a black screen with no input so no tty or cli or alt + sysrq +reisub so power button on case had to be used. Got to log in screen once powered up again. imo this is a xorg bug which is well reported all ready but cannot get a fix for this particular hardware configuration in order to confirm this or not. Once logged in to default desktop session if power button at top right of screen is used to select restart or shut down the machi (Hardware)
