Weird... X can handle 24 bit color just fine. My first guess is your graphics card (the "oldish s3" you mentioned), doesn't have the muscle to power both the high resolution *and* the 24 bit color depth, so X is smartly lowering the color count when the card complains. There are a lot of "odd" resolutions which monitor vendors use which are not necessarily fully supported by graphics card vendors. For example your graphics card might support 1600x1000 resolution at 85Mhz with 24-bit color but if you try 1601x1000 resolution at 85MHz with 24-bit color, the graphics card will either not work at all, or it will downgrade the MHz or color depth. Your monitor wants to use one of these "odd" resolutions, namely 1680x1050. It can be a pain in the ass to figure out what will work and you will need to read the documentation for both your monitor and your graphics card to figure out exactly what each will support. kind regards, jcr
