I have an Asus eee r101 pc,and wonder if anyone knows how to update the graphics drive in Ubuntu 12.04
Go to 'System Settings' and under 'Hardware' section click on 'Additional Drivers'. It will automatically search for drivers and it will ask if you want to install the graphics drivers.
System Settings -> 'Hardware' section -> Additional Drivers
You can search for System Settings in unity dash.
Just hit Super Key(that key which has windows logo between left Ctrl and left Alt on the bottom left of keyboard) and type System Settings and hit [ENTER] to open it.
