Hibernation sometimes works, but many times:
- Screen flashes then goes blank, black, or just returns to desktop view.
- Everything freezes entirely, not even typing in the blind works.
- Nothing happens after 1-2 seconds of disk I/O.
- Nvidia Optimus using
bumblebeeand proprietary drivers.
- ArchLinux with everything at the latest
- Unencrypted drives
bumblebeefails after wake from suspend, which I don't know if related.
There are not errors or anything in
journalctl, except that the log ends with:
Nov 16 14:20:34 localhost kernel: PM: Syncing filesystems ...
How can I dig further in the issue or how to resolve it? I waited about 5 minutes at that hibernation attempt before I force-shutdown the PC.
