Package: one of xwindows installation packages Version: depends In debian 3.1 (and older versions) xwindows system installation menius when choosing video card driver, there is no radeon driver choice included. If you have Radeon and select another driver the xwindow system will not work or monitor will show 60Hz and no more. When radeon driver name is written directly into XF86Config-4 file everything works fine. I think you just forgot to include the "radeon" option into driver selection menius. It took me 2 days to find out how to fix the problem.
