Random flickering of QHD monitor #20

Closed pjeorge closed 4 years ago

pjeorge commented 4 years ago

Hullo, I followed your guide. Everything works great. Thanks! But I get random flickering from the built-in QHD monitor. I tried even with the guest accounts but it happens there as well. What could I do to debug and improve the issue?

Thanks for your time

(I wasn't having this problem with Linux or with Windows on the same machine) (I saw that there is a Beta version with Big Sur, but I'm more interested in a stable setup nowadays)

@pjeorge what do you mean by random flickering? does this occur after sleep? -- I think this happens after a sleep sometimes because of the QHD screen. run this command and let me know the results.

sudo pmset -a sleep 0; sudo pmset -a hibernatemode 0; sudo pmset -a disablesleep 1;

the issue i think is random artifacting which you are describing which happens after wakeup

I actually already tried that but to no avail. The screen basically turns completely off and on in less than a seconds. It happens also from a fresh startup without sleep.

@pjeorge add this into the plist config

-igfxmlr -igfxonln=1 igfxonln=1 igfxmlr

add all of those as separate arguments using clover configurator the config.plist

use the - and without

@pjeorge let me know if it helps

Had to revert cause I wasn't able to login in without external monitor. Still, thanks! I'm going to try Big Sur EFI folder.

Nope. Still flikers after sleep disabled. When from shell mode gets detached and used standalone without external monitor 🤷
