[wlug] Radeon HD 3450 Graphics Card and a Acer 22" LCD Screen

Hello All Hey I have a Radeon HD 3450 Graphics Card and a Acer 22" LCD Screen. When I enable the Radeon restricted driver, the desktop area is now larger than my screen are abut most of it is not my background image but black screen. I wanted to enable the driver to run flightgear, but its just so damn ugly with big black bands of solid black that I can stand it no longer and disable the Radeon driver. When I do that I get my normal desktop back that does not scroll beyond the limits of the screen, but flightgear becomes completely unrunable due to it becoming agonisingly slow. Is there anything that i can do without having to replace this graphics card? Glenn Morrissey.
