I bought Asus K53U laptop, which is Ubuntu certified with pre-installed 11.10. The graphic card is Radeon HD 6290 but 720p playback is terrible. Even page scrolling in Firefox is very laggy. Proprietary drivers are installed by default.

How is this possible, why is the laptop Ubuntu certified if the performance is poor? Any solution to this?

I just did apt-get autoremove, and after that, this message came out in terminal:

Error inserting vesafb (/lib/modules/3.0.0-15-generic/kernel/drivers/video/vesafb.ko): 
No such device

Could that be the problem?
