i have installed fglrx drivers from Additional drivers then at catalyst app there is 2 options intel or amd driver first the AMD is active by default but the graphics are glitchy during HD video or something so i activated intel, graphics is much better now i dont understand how ! AMD should be better

so,

how can i switch between cards without restarting? does ubuntu switch to amd automatically when needed for 3D games? and can i configure intel card like i can configure amd catalyst thanks

  1. Ubuntu does not switch adapters automatically.

  2. You do not need to reboot to switch adapters. You can only log off and log on.

  3. Your problem may be related to a wrong or badly installed AMD driver. But you did not provide any information that allows to check it.
