Question: black screen in Catalina

I'm suffering from a black screen on my MacBook Pro after every sleep event.

Only way out is to hit the off button and restart every single time.

Does anyone have a solution?

I just came up with a workaround where I DID NOT get the black screen after locking and walking away for a long time. I went into Energy Saver in Preferences and turned off Automatic graphics switching, and checked Prevent computer from sleeping automatically when the display is off. Screenshot of my settings attached.

I have to do the same thing too - turns out the MCTTriggerGraphics.plugin and Trigger5Core.kext are the culprit, and I can even put them back after restarting - the moment I put the back the issue came back.

I remembered at some stage I used a USB Video Graphics adapter from j5create and must have installed one of their drivers then. A search on their website indicated that their Mac drivers are not fully compatible with Catalina yet and they are asking people to delay upgrading to Catalina.

As I don't use either of those devices now I am happy to remove those drivers.

Hopefully my MBP would now stay this way and all will be OK...

Thank you to whoever found this solution/workaround.

My work MBP is having the same issue, 2019 15 inch MBP. If I lock the screen and wait for it to turn off I don't get this issue, but if I do the same thing and walk away for a few minutes the issue happens. Also the touchbar shows options like it's unlocked, like my outlook was the last program with focus, and when the issue occurs I see the outlook options in the touchbar.

Looks like it is no only me who is suffering from this issue. And just for the record I have a 2014 13" Retina Macbook Pro. Tried doing (multiple) SMC and PRAM/NVRAM reset but to no avail, was going to try reinstalling Catalina again but will now hold off since i'm not the only one facing this issue.

I did some research and found something perhaps unrelated, and that is to change the hibernatemode to 25 (i.e. full hibernate). Just going to try it and see if it can be a viable workaround, but obviously hoping for a fix soon.

That sounds like an interesting workaround. Not sure how sidecar is involved, but maybe turning off sidecar helps?

How do I go to arrangement when I have black screen on my laptop? Can I connect sidecar from iPad side and get the screen in that way? Sidecar is not connected for me when the issue happens (it happens every time the screen powers down due to inactivity)
