What is the difference between Xcfb and Xcfb2? What is the significance of running Xcfb with the -dpi 100 switch? I have been running on a 100 dpi display without it for a while. Tom Epperly

Xcfb2 is somewhat later than Xcfb; it did not see full field testing, and was therefore not the default server. It is somewhat later, which means some nasty bugs had been fixed. But its important difference is that stipple fill is maybe 4X faster than Xcfb, very important for ECAD applications. But better is to upgrade to Ultrix 3.1/UWS 2.1, and use Xcfb from there. It has very much better performance for many graphics operations. The upgrade is quite painless; it is done in place without reinstallation of the base system. - Jim Gettys
