Hello There is a fix for your problem but you need to work a little without seeing a correct screen. * In the startup screen in Ubuntu you give User and Password (with a corrupt screen) * In the Ubuntu desktop screen you try to start a terminal window (It is not easy with a corrupt screen) * In the terminal you give the input: sudo nautilus * Go to /usr/share/applications and start "Screen and Graphics" ( * In "Screen and Graphics" you choose graphic driver (vesa works good for my A21p) and what screen you have (I use LCD) * Now you have a correct screen and when you start the computer next time the screen is correct. Good luck Per-Olof Thureson
