I have a problem when resuming from hibernation. Sometimes work fine, but most of the time it freeze before the display manager.
I tried to remove the "quiet" from the kernel parameter, but doesn't show anything.
The symptom is, there is a cursor blinking, like usually waiting to run the display manager. But around 1 minute later, the cursor does not blink anymore. Keyboard or mouse help nothing.
Reboot, then run the "journalctl -xb -1" shows the previous success boot, not the one failed when resuming from hibernation.
Tried to use linux-lts, it did not work also.
Does anyone have idea what is the possible solution?

I tried to disable the lightdm, and used the "systemd hibernate" in the TTY. It seems work fine, but I tested once only. So, I reboot, and start with lightdm, and run the Xfce4. Then when I wanted to hibernate, I switched to TTY2. Then from the TTY2, I used the "systemd hibernate".
And when I resume, it works fine, and resumed to the TTY2. And I can switch to the TTY7 for the Xfce4. Then after I finished my work, and wanted to hibernate again. I found that, all the other TTYs cannot work. All the other TTYs show the output as in the TTY2. They "look like" freeze, but I cannot confirm yet. Need to try to enter some command blindly.
I suspect it is related to nvidia. I will check for the dmesg next time.
When using systemctl hibernate from another TTY, then resume, then the X windows workable. But after some time, switched to the TTY, TTY "looks" freeze. But I can run the "systemctl hibernate" again from the TTY. Then resume 2nd time, this time is totally freeze. Cannot blindly enter any command.
I tried to switch to uswsusp, but freeze also.
Cannot check with dmesg, because it is freeze. SSH server is not running either.
I have similar behaviour on my desktop machine with Arch 64 bit, KDE, SDDM. It goes to suspend without problems, but resume from hibernation (suspend to disk) always fails. I can't check logs because i don't have anything exept when Arch was booted and worked fine till resume from hibernation. Cursor blinks, nothing works, cant swtich to tty, only reset. I have this on all kernels. I've been fighting with this since i bought an Skylake and Z170 platform...previous Haswell had the same problem for about 1.5 year till bios was relased...but for Z170 i checked six bioses...nothing so far - it must be something in kernel...
What is more strange, and funny - suspend to RAM works always, whenever i want, how many i want...suspend to disk fails often. I thing that it is something related to this:
It works when i just boot, suspend to disk, resume from suspend to disk. I do something...suspend, resume - black screen, blinking cursor, no display, have to reset.

This is an old post. But just found that it seems like being solved since few days ago. Though I tested once only with hibernation and it success.
The symptom is, every time shutting down will display the systemd messages (GRUB_CMDLINE_LINUX_DEFAULT="", no "quiet"). However, previously, shutting down only shows the blank black screen.
I am now using linux-lts 4.9.13-1 and nvidia-dkms 378.13-2
