Is anyone knowledgeable about Xvfb? Here is how to reproduce the problem I have: Xvfb :1 export DISPLAY=:1 xboard Running xboard crashes the X virtual frame buffer with the message:* No copyPlane proc registered for depth 4 I also tried running Xvfb with -pixdepths 4 which didn't help. Some other programs (xterm, gimp, and display) did not crash Xvfb. I tried some explicit screen definitions (e.g. -screen 0 1600x1200x4 or 12080x1024x4) but this only changed the number at the end of the error message. This seems like pretty basic use of Xvfb and worked fine for me before in Solaris. Currently I am running FC2 with the 2.6.6-1.435.2.3 kernel, xboard-4.2.7-3, and xorg-x11-Xvfb-6.7.0-5. I don't think the hardware and softare versions matter so much because I have the same message on an i386 laptop running redhat 7.3. Background: I run a chess program (crafty) using the xboard (zippy) interface that allows it to play automatically on the internet chess club (icc). I want to run this in the background on a machine that will not always have X running. In the past, I used Xvfb (X virtual frame buffer) to have it run in its own sandbox so xboard can think it is connected through X to a monitor. However, the same configuration doesn't work. It is a little hard isolating the problem, because the hardware (SUN Sparc to Intel), OS (Solaris to linux) and versions of all the programs have changed. -- Phil *There are additional error messages when Xvfb runs, about a font not being found and also several about IPV6 (which I have turned off but Xvfb doesn't know). However, I have reason to believe they are not the source of the problem.
