Package: xserver-xfree86 Version: 4.2.1-3 I am using an ATI Radeon 7500 QW graphics card, with an Iiyama 1600x1200 LCD display, connected to the digital port of the graphics card, with a resolution of 1600x1200. The 1280th pixel column on the display is missing. That is the 1279th pixel column is directly followed by the 1281st pixel column. We have four of these systems set up, and all of them display the phenomenon in Linux, but not when we tested it with Windows.
