xorg log

After the latest update to 2.99.917-45-g653b8a4d8321, when the system issues dpms off, it won't turn on on a key press event. I have to switch to console and back to turn it on.

Hmm, worksforme. Please grab a full-debug log and lets see how it gets confused.

One minor tweak, as I see that you go through DPMS sleep/standy. But also I've added a couple of steps to the logging.

Ok, that extra DPMS sleep is starting to explain everything. That might be the whole fix!
Comment 5 Chris Wilson 2015-01-26 11:45:05 UTC
Pretty sure it is now fixed. Please reopen if I missed something.
