Won't wake from sleep with 1080p screen #51

Open deformedcurv3 opened 3 years ago

I swapped out the original 1600x900 screen for a 1920x1080 screen and now it will not wake the display after sleep. I made no changes to my EFI partition, all I did was replace the screen. I played with the one-key-hidpi package but disabled it since macOS appeared to recognize it was a 1080p display on its own. If it sleeps for only a couple of minutes it will come right back up but if it sleeps for about 5 minutes or longer, the screen stays dark - no light at all. I press the power button to wake it and the power button turns green and the mute key light comes on but the screen does not. I have to force it off and turn it on again. Sleep worked perfectly before swapping screens. using hidpi vs not appears to have no affect on sleep.

Any ideas to fix sleep?

Try my EFI. It's more up to date

I have a T450s with a 1080p touchscreen from factory, wakes up fine from sleep for me but the problem is I am required to sleep/wakeup when I first turn it on to get rid of screen corruption (which weirdly doesn't affect the cursor)

This is because you have CSM support turned off. Turn it on. There's a weird bug for Intel HD 5500 on macOS that doesn't play nicely when CMS support is disabled (running fully on UEFI).

Thanks, I've figured that out since.
