This question already has an answer here:
I just obtained a small computer from ASUS with Ubuntu pre-installed. The scrolling, video, and animations are sluggish and choppy, though. The Details from All Settings states that the driver in use is "Gallium 0.4 on llvmpipe (LLVM 0x300)". However, the Additional Drivers claims that the driver in use is "drm driver for the Intel GMA500". I think that the computer is using the wrong driver, which could account for the choppiness in the scrolling and video. How can I correct this?
Computer Specs: 2GB RAM, 4x1.86GHz Intel Atom Processor, Intel GMA 3650 GPU
