**problems with DESQview/X PC running GRASS, XDPYINFO

[Michael Shapiro]

Well, I think this is the problem. You only have one PsuedoColor
visual and it isn't large enough. 16 colors isn't enough to run GRASS.

|>|Problems with new XDRIVER:(for GRASS running on a PC through DESQview)
|>|
|>|	1. When we start the monitor (d.mon start) it self it says

|>|	2. When we try to display a color vector map it doesn't use the
|>|assigned color (infact no color can be displayed at all)
|>|
|>|	3. When we try to display a raster map the monitor dies saying
|>|		"Segmentation fault"
