http://ubuntuforums.org – Dear all, yesterday I received my new TFT after my tube had begun colour flickering. So I connected it to my notebook running ubuntu 10.04 (company notebook so we can't change software so often). After booting and loging in I was able to work about 30 to 180 seconds then the system stoped. I was not able to do anything - no mouse movement, keyboard - no reaction - nothing! When I disconnected the TFT and worked with the notebook's LCD everything was fine also when I connected the old monitor. So it seems the problem is the comunication with the TFT.
