I am looking for a better Xcfb(X11R4) for my DECstation 3100 running Ultrix 4.0. If anyone at DEC has an improved version, I would like to try it. By the way, I had trouble installing X11R4 under Ultrix 4.0 because Ultrix 4.0 doesn't include /usr/include/machine/dc7085cons.h and some other pm*.h files. Also, xterm.c gives an error because fileno is defined with (int) in it. Please respond via EMAIL because I can't keep up with bboard reading. Tom Epperly epperly@osnome.che.wisc.edu

I've been running this for a day or so and it seems to work. I've seen one anomaly that I haven't been able to repeat reliably. Usually the load on the DECstation when someone is using the console but not actively doing anything hovers around 0. Twice now I've caught it idling at about .4, with cfpmax being the only thing apparently using time. If anyone else sees this or knows what might be causing it I'd like to know. Here are my changes: [I've seen this mentioned on the net already but am including it for completeness] DEC changed the definition of "fileno", requiring the following changes to two files in the xterm directory.
