Hi Pierre-Olivier,

I am running as root and I added the RemotePBuffer attribute to my Pixelformat.

If I have a monitor connected everything is running fine.
Then I unplug the monitor and reboot the machine. After that I get:

2007-02-22 10:02:56.823 ImageService[187] invalid pixel format
2007-02-22 10:02:56.823 ImageService[187] invalid context
2007-02-22 10:02:56.823 ImageService[187] Cannot create OpenGL context

So the RemotePBuffer attribute didn't seem to help. It looks like I have to find a way to make the hardware think there is a monitor connected. Maybe this works:

Btw. I am running on a G5:

I have made some tests. Indeed offline rendering does not work after a while if no monitor is connected. If you plug in a monitor all of a sudden everything works again.

Does anybody know how this can be avoided?
Are you using the RemotePBuffer attribute? What do you mean "after a while"? Any kind of error message in the output (QC will always print in case of errors)?
