The Radeon driver distributed with Ubuntu 10.04 and earlier distributions does not correctly detect monitor sizes. On Dell Latitude D600s with 14 inch 1400x1050 LCD displays, it incorrectly calculates a panel size of 370x277 mm and a resolution of 96 dpi, instead of the correct 124 dpi. The KDE desktop is misled by this when converting point sizes to pixels, and displays everything in unpleasantly small characters.
