Title: Problem recovering from a Sleep mode
Post by: some1 on July 01, 2018, 05:55:59 am
I did fresh install of Peppermint 9 and everything seems to work good except recovery from a sleep mode.

After I close a lid, laptop goes into sleep mode as expected, but when I open it again I'm mostly stuck with a garbled screen, or sometimes mouse cursor is missing, for some reason.

The same problem here. Has no one responded to your question as yet?

A conflict between the BIOS power management and Linux power management is the most common cause of such wake-up failure. Experiment with different settings in the BIOS to see if that might solve the problem. For example, a PC might not wake up if Advanced Power Management (APM) is enabled in the Power Options of Control Panel, the BIOS is configured to suspend the computer, and the BIOS time-out value is less than the value configured in Linux. To correct this, you would set the BIOS time-out to be higher than the Linux time-out.

I have tried so many things to fix this myself but I just stick to putting laptop to sleep with power button. It always comes out of sleep mode perfectly that way.
As far as the graphics glitch, installing laptop-mode-tools fixes that but you just end up with a blank screen instead. You can remove laptop-tools and effect is persistent.
I just change run-level and restart lightdm. People have had luck changing to GDM from what I've read, but I had no such luck.
Funny thing is, I never had this problem until 4.10 and later.  :(

Unfortunately, I did not find any of the relevant settings in BIOS of my laptop.

offtopic, but still worth trying. It's called TLP:
