Ubuntu 10.04 live CD with built-in GMA 500 support
If your notebook uses Intel GMA 500 graphics and you want to use Ubuntu, you may be frustrated that Ubuntu still does not include the GMA 500 driver. Someone has kindly made an Ubuntu 10.04 live CD with support for the GMA 500 chipset. It has been tested on the Acer Ao751h, Asus 1101HA, Asus 1201HA, Asus 91MT, Dell Mini 12, Fujitsu u820, Sony Vaio X, and Vaio P, all of which use GMA 500.
