mac wont wake from sleep after Catalina upgrade
Upgraded to Catalina several hours ago. iMac has gone to "sleep" 4 times and each time failed to "wake". Had to do "hard reboot". Anyone else?

I contacted J5 create customer service and they said they had a work around until new driver is updated:
It worked for me:

Hello Debbie
Before installing the latest driver software, it will require that we uninstall any currently installed j5create device driver first.
Please uninstall the driver software for the j5create USB adapter by doing the following:
1. Click on the desktop background
2. In the upper left-corner of the display, locate and select "Go" then select "Computer".
3. Select "Macintosh HD".
4. Select "Library".
5. Select "Extensions".
6. Find the following: "AX88179_178a", "MCT_trigger2.kext", "Trigger5Core.kext", "DJTVirtualDisplayDriver", "MCTTrigger6USB" and/or "MCTTriggerGraphics.plugin.
7. If any of these files exist, drag each of them to the trashcan.
After completing the uninstall process, proceed with the following:
Immediately after installing the device driver, please do the following:
Finally, after the computer has fully rebooted, plug the display adapter into a USB port directly on the computer, then connect the video cable into the video OUT port on the j5create adapter and into the video IN port on the display. Power on the display and ensure that the display is on the correct input mode, i.e. on VGA, HDMI, DVI. From here, on the connected display, you should see the desktop background and the display should now be ready to use.
However, if the display does not activate after everything has been connected, I recommend that you do the following:
Please be aware, If you are running the official release of macOS 10.15, we do not guarantee that this driver will allow for optimal functionality of j5create USB display adapter on your system. However, the driver being provided has been tested with the official macOS 10.15 Catalina release and we can confirm that the driver should allow for moderate functionality of the j5create device on macOS 10.15. Depending on your system specifications, you may experience general bugs. General bugs/glitches are to be expected with the beta driver, however we welcome all feedback!
Please let us know if you have any questions or concerns regarding to this matter!

Got the same thing again today after doing the 10.15.1 update. So mad.
Me too, now I have two displays that won't work at all......... I am so upset with this, this is a lot of work.
I did the workaround and just had the same issue. Sorry.
I’ve done the update and mine seems to working fin now. Have you tried?
I tried the Opt+Command+p+r and it does not work.
If Apple spent half the money did photoshopping the image of Catalina from a fancy helicopter, we would have a functioning OS that didn’t hold MacBooks hostage in perma-sleep.
There are many people who make this suggestion, but I have this problem EVEN with a CLEAN INSTALLATION!!!!!
All- I have had enough and have decommissioned catalina. Now using Mojave...so much better
Has there been a solution to this? I have tried NVRAM, SMC, and safe boot but the problem persist. Thanks.
I have still issues. Can you help me to understand what NVRAM and SMC means. I would try. Thanks.
Same issue.
any solution?
Yes
Thank you man 💪
it seems to solve the saga on my 10.15.2 (15" 2018).
@Apple, 🙏 check it out
Forget about sleep mode, you will not solve it forever, switch back to authentic Apple blade!
