Hi  Arnold,

May I suggest you try the following that has been  sent to me sometime
ago ( courtesy of Mauro Tortonesi).

" I used to have a SiS card. Usually SiS cards need the following
line in /etc/X11/XF68config (in the "Device" section):

 option "no_bitblt"


 An extract from my XF86config follows:

Section "Device"
    Identifier  "SiS SG86C201"
    VendorName  "Unknown"
    BoardName   "Unknown"
    Option      "no_bitblt"
    #VideoRam    2048
    Clocks  25.07  28.32  39.83  72.16  49.79  77.14  35.95  44.72
    Clocks 129.50 119.53  79.67  31.51 109.52  64.71  74.68  94.55
    Clocks  12.53  14.16  19.91  35.95  24.90  38.63  17.99  22.36
    Clocks  64.73  59.75  39.83  15.76  54.90  32.35  37.33  47.27
EndSection

 If it still does not work try with:

Option "no_linear" (perhaps in combination with "no_bitblt")
 
 or

Option "no_imageblt"

 or 

Option "noaccel"  

 Take a look at /usr/X11R6/lib/X11/doc/README.SiS ;-) "

I hope this can be of any help.

Good luck.
