I don't know what the proper name for this is, but for now I'll call it a desktop raster. I'm talking about the actual content of a desktop. This is distinct from the part that X shows. There seem to be three different 'rasters'. One is what you adjust when you adjust with the monitor buttons and/or knobs. Another is what is set by the modlines in the XF86Config. The one I'm talking about is distinct from these. This is the part you actually want to see. The problem is that the edge of the desktop extends beyond the edge of the sweep of the beam. For example, the little button at the end of the kicker is completely off the edge of the display. Moving the display position and width with the monitor controls doesn't fix the problem. I believe this is a result of my having increased the vertical sync rate. Perhaps the only solution is to reduce it back to where it was. It seems to me I might be able to tell X not to paint the desktop as wide as the raster it generates. It's raster seems to overshoot the edge of the monitor's display. I don't know if any of this is making sense, but if it is, I wold be gratful for help. Steven
