Intel Mac + Catalina = no clamshell

Solved my 5.2.5 issue (and now able to do everything I want w/ clamshell working!)

Fully uninstall 5.2.5
Turn laptop off
(Then I had to disable csrutil and delete the old kext which would never delete during the uninstall: )
Boot to recovery, open terminal, csrutil disable
Reboot again
Navigate to: Macintosh HD\Library\StagedExtensions\Library\Extensions\
Delete "DisplaylinkDriver.kext"
Install 5.2.5
Reboot normally
Enable Screen recording
(Then you'll probably want to renable csrutil: )
Reboot to recovery again
Terminal: csrutil enable

The hidden one in there of course is deleting the bad kext which can't be done without disabling csrutil
