I know that it is somehow related to the video driver and hardware acceleration, but what exactly this driver is? It seems it is not the video driver itself. So, what actually it is and how exactly is related to the video driver?
Before installation it is named "Cedar Trail drm driver in DKMS format". After installation it appears as "drm driver for the Intel GMA 500".
After installing this driver, another driver appears, named "Intel Cedarview graphics driver", that seems to be the real graphics driver.
Both are installed on a netbook with Intel GMA 3650 video adapter. Linux Mint 13.
