NAME

Xqdss - VAXStation II/GPX server for the X Window System  

DESCRIPTION

The QDSS hardware in the VAXStation II/GPX supports 8 plane or 4 plane displays.

 

OPTIONS


-bp pixel-value        set default black-pixel color

-wp pixel-value        set default white-pixel color

The server also takes all of the standard server options (See /fIXserver(1)/fP for a complete list.)

 

NOTE

You need to make sure your kernel is configured with DMA_BUFSIZ set to 10 in sys/data/qd_data.c, or things won't work right.

 

BUGS

Currently only numeric arguments from #000000 to #ffffff are accepted for default BlackPixel and WhitePixel, and no screen number is accepted.

The GPX hardware contains a polygon edge address generation engine which does not conform to the polygon edge model specified in the X11 protocol document. The effect is that GPX polygon edges extend on average one-half pixel farther out than they ought.
