No need for that since we're starting our own Xvfb > I tried these steps : > 1. Start container in level 3. > 2. lxc-console into container > 3.

I don't have SELinux to contend with; you'll have to fix that first. Here is the script I use which runs at boot time. The apps are all run as an ordinary user "ag". I use display :1 out of habit (after testing on machines where there is already an existing :0) but you can choose anything reasonable. # Commands to provide display environment for AGServiceManager & vic # su -c '/usr/bin/Xvfb :1 -screen 0 1024x768x24' ag & su -c '/usr/bin/mwm -display :1' ag & # Run the service manager as user 'ag' # su -c 'DISPLAY=:1 /usr/bin/AGServiceManager3.py -d' ag & Thats enough to run what I need in that container without further input from me. If I do want to use that X environment remotely for some reason, I ssh as user ag (or lxc-console and su - ag) into the container and run: x11vnc -rfbauth /home/ag/.vnc/passwd -display :1 & (assumes you've previously set up a vnc password) and then from a remote machine, run: vncviewer conatiner_ip_addr:0 chris Christoph Willing +61 7 3365 8316 QCIF Access Grid Manager University of Queensland ------------------------------------------------------------------------------ Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl _______________________________________________ Lxc-users mailing list Lxc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/lxc-users
