I cannot switch dual graphics card in Ubuntu, because ATI card always freezes. So I wanted to set it from bios. As dell's driver update page(http://www.dell.com/support/drivers/us/en/19/DriverDetails/DriverFileFormats?DriverId=R314952) has update drivers for bios. With fear of screwing my computer, I upgraded the bios software, to enable their number 1 feature (1.enable Discrete AMD VGA fixed mode Support, listed under Fixes And Enhancement). After upgrading, I did not see any change. There is no option to enable or disable single graphics card. So what's the point of letting user download that software.

Games: FrozenBubble, Neverball, Vertigo, Zaz, Supertuxkart, Some form of tetris, Gweled, Blobby Volley 2, LBreakout 2, Frogatto, armagetron, xmoto, PokerTH, trackballs. Others: Cryptkeeper (hide directories), audacity(bundle mp3 support), openshot, desktop recorder, clementine-player(music), smplayer (if everyone has vlc), cherry--tree(note taking app, http://www.giuspen.com/cherrytree/), tasque, focuswriter and virtualbox to run ubuntu.
