Bugs should be reported to
reporting bugs, please check the X server log file, which can be found
/var/log/XFree86.0.log on most platforms. If you can't resolve
the problem yourself, send the entire log file with your bug report. Please
don't edit out what you think might not be important. The information
contained in the log file is there to make it easier for the developers
to determine what is going wrong when there are problems.
If you have patches (bug fixes or enhancements, etc) that you'd like to submit for inclusion in a future version of XFree86, please send them to fixes@XFree86.org .
