On my Asus x201e, after updating from 13.04 to 13.10, intermittently when awaking from suspend, my screen will blink to a black screen a few times, offer a lock screen, and then go back to suspend unexpectedly (during this it is possible to quickly login to the desktop before the system suspends again). This will repeat each time I subsequently awake it from suspend. Only a restart will escape the suspend loop.
The problem only occurs when suspending by closing lid, not by manual (pm-suspend) or menu suspend. Opening the lid after a manual or menu-initiated suspend works as expected.
When an external monitor is attached, the black screen and second lock screen still appear twice upon wake, but the system does not fall back into suspend (though networking is disabled and needs to be restarted).
This issue arose in tandem with the already raised issue regarding networking not restarting on wake from suspend, though appears to be distinct from that issue and persists after a fix is applied for the networking issue.
This issue only occurs on waking from suspend, never upon booting. And only on the second suspend cycle after reboot.
Any ideas for a workaround?
