You have been subscribed to a public bug: I have several Dell Laptops model Precision 5520. Ubuntu LTS 20.04.2 seems to run fine without issues. After do a software update which appears to update to LTS 20.04.3, the laptops no longer boot properly. I end up at a black screen with an underscore cursor blinking at the upper left. If I then hold the Alt key down and click the right arrow a few times followed by the left arrow a few times, eventually I see the normal GUI login screen and I can log in.
Please let me know if there is anything that can be done to avoid this problem. I have tried on several Dell laptops and I get the same behavior on all of them. There seems to be something broken in Ubuntu 20.04.3 for these lapotops.
