The GRASS Xdriver only works with 256 color displays. Make sure that your 
display mode is set to 8bpp for 256 colors. That should fix it (I'm 
running GRASS under RedHat4.0 on a Cyrix 6x86 P166+ and it _screams_. The 
video display, Jaton Video-58P with et6000 chip and 4meg MDRAM, is the 
fastest I've seen. Good luck!
