Correct Hibernation settings for Catalina

[Nexxusone]

o.k used the master disabled command from utils (gatekeeper)

and disable hibernate.command to turn off hibernation... still just not enough

I'm thinking Catalina updates may have altered the way of setting these settings.

I can NOT replicate a working hibernation setting(s) on a new fresh install

on 10.15.3 / Asus b360g /i5=9400f / rx5700 8gb pulse

now I know it can be done as have a CCC clone of a WORKING 10.15.3 which was updated from 10.15> 10.15.1> 10.15.2> etc -  so I can always reload that

by working I mean screen saver comes on after 5 mins - blank screen at 10 mins then into sleep mode , monitor powers off and then pc powers off, to a flashing power button, leave alone 30 mins or 8 hrs and wiggle mouse it all comes back working fine. SO I KNOW IT CAN BE DONE.

a new fresh install gives me VTXDecoderService error, when it goes from screen saver to blank screen and panics and rebootd

any ideas?

the problem is I applied so many fixes to 10.15 / 10.15.1 /10.15.2 I can't pinpoint the correct fix....

an advice: disable hibernate ever, use sleep

 

use shikigva=144

[Nexxusone]

both using same clover EFI (copied over) and Bios settings unchanged, so its a Catalina setting at fault.

my current settings in the working 10.15.3 CCC clone - which goes off for 8+hrs and comes back on fine and fully working

just agdpmod=pikera in boot arguments

System-wide power settings:

Currently in use:

autorestart          0

Sleep On Power Button 1

hibernatefile        /var/vm/sleepimage

proximitywake        0

powernap             1

gpuswitch            2

networkoversleep     0

disksleep            10

sleep                1

hibernatemode        0

ttyskeepawake        1

displaysleep         10

tcpkeepalive         1

womp                 1

 

this works fine.....

 

will do a clean install of 10.15.3 with same EFI, and do the master disabled and hibernate-disable.command, but add in shikivga=144 ( I had tried 128) 

this will sleep and wake fine if set to 1 min screen saver and 2 mins screen off - but if LEFT idle for 5-10 mins panics and reboots.

so will try fresh... luckily I have 2x clones of 10.15.3 on separate bootable media to restore from (2 for safety incase one goes corrupt or accidental changes)

so will play tonight on fresh install.

Well........ I'm not sure if shikivga=144 fixed it, or myself putting in correct password in terminal when it asks for password and I was putting xxxxxx and it should have been yyyyyyyy.........

any way, clean install NOW fully working!!!! 

what does shikivga=144 do? 

=128 is for AMD+IM/IP with all decoding via hardware, correct? , what is =144 doing?

spoke to soon it did a couple of cycles of sleeping / use / normal shutdowns and then started panicking .... so panic is not straight away....

o.k for now the 10.15.4 Beta1 has 'FIXED' the RX5700 reboot / kernel panic on entering Display off, so there seems to be a RX5700 / MacOS fix in the new Beta 10.15.4
