I am running ubuntu 12.04 on a Toshiba satellite. When I start my computer in begins to load and then goes into a text only mode. It then keeps running assuming drive cache write through and then say that it failed. The only way I can get my computer to start up GUI is with a ctrl+alt+F1 and then "startx". there have been no hardware changes to my machine recently. Does anyone have an idea on how I can fix this? Any help is appreciated.
