MacPro 3,1 (2008) suspend hangs

[Gary Renes]

Thanks for the reply.

> Automatic sleep is something I always turn off on other OS I am sometimes forced to use, but on FreeBSD I've never seen it in the first place, and I'm not aware of anything in the base system that would do this - in fact, it would be a major problem if there were such a thing, for reasons which should be obvious.  Do you have something other than the base system installed?


It was late when I wrote my email last night and realised once I’d gone to bed that the last part about automatically going to sleep may be confusing. I’m dealing with a few issues on the system, and I’ve accidentally wrapped two of them up in to one email. Apologies!

> If by sleeping automatically you mean only when the lid is closed, then try checking in /etc/devd/, but I'm not sure that will be it, since when I installed my system there wasn't anything lid-related turned on by default.  Make sure also that sysctl hw.acpi.lid_switch_state is NONE.


The bit about automatically sleeping is when the machine is running X - the monitors go off and won’t come back on without restarting X. From what I’ve read this is an X / Nvidia driver issue so please ignore this part of my email.

Apologies again for the confusion. Just to clarify, it’s a desktop machine with no lid to close, and it doesn’t automatically sleep via ACPI, it just hangs when trying to suspend.

Regards,
Gary.
