Public bug reported: With any Ubuntu variant I've tried (Ubuntu, Ubuntu Mate, Ubuntu Budgie), the graphical installer works correctly, but on every post-install login, the screen goes black at the disk decryption screen.
Other things seem to be working. If I'm careful, I can enter the disk decryption password and tell (via sounds) that I've gotten through to the login screen, but the screen remains dark. This happens with standard or minimal installs. If I then try to boot with the previous kernel--4.15.0-20-generic-- everything works flawlessly. The only non-standard thing about this system is that I replaced the onboard wireless card with an Intel Dual Band Wireless-AC 8625. --- I don't have a clue about kernel debugging, but I can provide further system info as needed.
