Erik, thanks for the tip. My motherboard was already in Auto mode. I tried switching it to "S3 only" and also toggling ACPI 2.0 and other suspend-related options to no effect.
Attempting to suspend in S1 only mode results in an altogether different problem, where the computer powers down into suspend, but instead of resuming, instead simply reboots. -- [Asus P5E-VM HDMI] suspend/resume failure [non-free: fglrx] https://bugs.launchpad.net/bugs/347657 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
