I have installed ubuntu 13.04. I can boot successfully to ubuntu screen. However, during boot, I get error messages for 1 second or so, and continues to boot.
One of the error message was:
radeon 0000:01:00.0: Fatal error during GPU init
My laptop has intel integrated graphics card and radeon HD 4550.
Does it mean my amd radeon is not activated yet?
How can I enable it?
