Description of problem: xorg.conf does not load extmod by default and has to be added. extmod not being loaded causes windows to appear black when minimising and alt-tabbing, certainly in gnome, untested in other environments. Version-Release number of selected component (if applicable): How reproducible: Install FC6 i386 with an nVidia gfx card Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
xorg.conf does not _need_ to load extmod by default. If you don't specify which modules to load, it loads a default set, which includes extmod. I suspect you have installed nvidia's drivers, using a package that (erroneously) adds the "glx" module to the Modules section even when that section does not exist, which causes the server to _only_ load glx.
