[XFree86] Need Help With A Video Problem

[Kemp Byrd]

Hello,   I just installed FreeBSD 4.8-RELEASE #0 on a PC.  The hardware specifications are:   AMD 500Mhz CPU 384MB of RAM SiS 530 Video Card with 8MB of Shared RAM AOC Spectrum 7Glr monitor   I am using the XFree86 Config file: /usr/X11R6/lib/X11/XF86Config   I can get the graphical environment to start.  My problem is in the video quality of the screen.  There is a great deal of "snow".  When I move the mouse, the "snow" becomes worse.  If I move a window around on the screen, the picture quality deteriorates to the point of unreadability.    What can I do to remove the "snow" look on the screen?  Please reply back with suggestions to solve this problem.   I also tried Red Hat Linux 9 and had the same results.   Thanks in advance for your help!   Kemp Byrd
