I am running into a weird problem. I have a tool which allows for
offline rendering of some quartz compositions (somewhat like the
Apple example QuartzComposerOffline).
It has been running for test quite some time on my development
machine (a couple of months).
Now it is going to be deployed and it did work initially without any
problems. But suddenly I get errors like this:
The last message is from my code and telling me that an OpenGL
context could not be created.
I could not find a solution why this would happen just suddenly ...
I rebooted and I even tried the QuartzComposerOffline example which
is giving me exactly the same errors:
The machine is running in the server room without anybody logged in
and without monitor. Could this be the problem?
I ran scutil to see if maybe power management was enabled, but it
does not look like:
> get State:/IOKit/PowerManagement/CurrentSettings
> d.show
<dictionary> {
Wake On LAN : 1
Sleep On Power Button : 1
System Sleep Timer : 0
Wake On AC Change : 0
Automatic Restart On Power Loss : 1
Wake On Modem Ring : 1
Reduce Processor Speed : 0
Disk Sleep Timer : 0
Display Sleep Timer : 0
Dynamic Power Step : 0
}
