Acer Travelmate 2410 with display probs

I've recently installed a new xp & ubuntu onto this std laptop and all was working fine for a few days. Next thing I k**w is when I boot up the screen display is best described as funky (when booting up the Acer appears in low def, when the screen displays black there is green shadows to the right of the characters, and when I boot into firefox the white background appears pink. When I highlight the text it turns purple). This seemed to sort itself out after 30mins but then reverted to this strange colour scheme. I've tried to uninstall the vga driver thinking this was the problem but to ** avail. I **ticed a similar problem with a**ther user but was wondering if perhaps this may be the graphic card burning out or a cable issue running from the lcd to the motherboard? I am going to plug this into a**ther lcd to check but any further info would be appreciated. Thanks
