This question already has an answer here:
My graphics graphics card is a Radeon HD 4250 and ATI has dropped the support for x-server version higher than 1.12. Are there any alternative graphic drivers I can use besides the opensource driver, Gallium 0.4. If not what's the best config I can do to boost performance so that it's similar to the proprietary driver. I'm running Ubuntu 13.10 64bit, and my graphics are: Gallium 0.4 on AMD RS880.
