Created attachment 139008 [details] Initial boot - everything was fine. If I leave my computer at the logon screen and the monitors fall asleep, I cannot wake them. Requires a reboot. Looks like there was a dmesg error, and Xorg.0.log reflects a failure when attempting to use screen 0. I'll include the xorg.conf because that may have had something to do with it according to the Xorg.0.log.
