Add this line to your .xinitrc file xdpyinfo -display :0.0 The hostname is not specified. --Duane -------------------------------- Hi Duane, I put the line you suggest into .xinitrc, but I still have the same problem. I also went into /etc/hosts after doing this and tried two ways of setting hosts: 1. 127.0.0.1 localhost xenon 2 127.0.0.1 localhost But I am still seeing the "out of display lists" message. It seems like the xdpyinfo command does not do anything. The only thing that I have done which changes the error message is to set /etc/rc.conf hostname="xenon" Then in .bash_profile put "DISPLAY=xenon:0.0 export DISPLAY" Then I get the different error message: "_X11TransSocketINETConnect() can't get address for xenon:6000: hostname nor servname provided, or not known Error: Can't open display: xenon:0.0" So I guess now I have tried every combination of the following: setting hostname in rc.conf to either "" or "xenon" setting "DISPLAY=xenon:0.0" or leaving that line out in .bash_profile And finally, putting in xinitrc "xdpyinfo -display :0.0 or just leaving that line out. So I am still baffled. Sincerely, Rob. -- ----------------------- http://www.roblytle.org Rob Lytle Home Page
