How is that the same this has nothing to do with a lock the screen? When I said it lock I mean when you boot up the machine after logging in with user. And and password and sighting in you get a black screen and there is nothing u can do. Also know as lock. Not as in a lock the screen with Carl alt delete and it goes black!

So it def has nothing to do with VMware video display drivers for sure. I remove xbuntu and installed Ubuntu and you can install 4.19.1. .2 .3 .4 but the log in process takes a long tine and it eventually logs you. Except kernel .5 and .6 completely black screen after long on. Same goes for all 4.20 RC releases
