Computer cannot wake after auto-suspending itself - gkk1969 - 01-14-2018
Hi,
I have MacMini 2.1, Core2Duo @ 2 GHz, 2 GB RAM, running Linux Lite 3.6 (x64), kernel 4.4.0-93-generic.
LL runs very smoothly on it. I'm very pleased. The only problem is my MacMini cannot wake after being auto-suspended (based on Power Management setting). What is interesting is that if I see the computer going to sleep and shortly go and press the power button to wake it up, it will. Bit if I leave it overnight, the next day when I press the power button, it only shows a black screen and never wakes up (it just hangs) and I have to restart it.
I tried to fix this by reading various posts, but it's not working great. I have the following setting in GRUB:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=/de/sda3 video=1280x1024 reboot=warm,cold,bios,smp,triple,kbd,acpi,efi,pci,force"
GRUB_CMDLINE_LINUX="module.sig_enforce=0"
In The Power Management settings I have:
System Sleep mode - suspend after 30 minutes being inactive
(the other settings I did not specify since think they are not relevant to the problem)
I used this MacMini with Bootcamp which I usually booted to Win7 and the sleep/suspend modes were working correctly (same for the OSX on the maachine). Also, I could wake the computer by just clicking with the mouse or pressing a key (while with LL I had to press the power button).
I'd appreciate any help on my issue? Thank you!
Regards,
George

I have the same problem, different box. Tried wiggling the mouse, hitting various keys, esc, ctrl, ..., and tapping the power button. Solid black screen. Had to reboot.
Here's my box info from:

sudo dmidecode -t 1

Useless fix!
Nothing new to me try ctrl+alt+f2,f3,f4,f5,f6
log in with your username and password even when it is not shown when you type it. then hit enter
type sudo htop
type your password again and hit enter
use arrow keys and find Xorg
kill it with f9 and send "sigkill" to Xorg
press ctrl+alt+f7
Done all programs gone thats it. a faster way to fix it (Xorg fixed). Sometimes reboot needs to be more fun now it is.
