[Bug 1870816] [NEW] received update then got stuck on blackscreen in login screen. Changed "qiuet splash" to "radeon.modeset=0" in order to boot normally.

[Tymour Kadry]

Public bug reported:

I received an update yesterday 3/4/2020 that had important security and
kernel updates, so I launched it as I usually do with any security or
kernel updates I receive. It downloaded and installed the necessary
files and requested a restart.

I restarted and kept receiving a black screen with only my mouse visible
on the login screen and nothing I tried worked until I went to Grub and
pressed "e" then changed the "qiuet splash" to "radeon.modeset=0" (since
my graphics card is ATI Radeon) in order to boot normally. And it
worked!

But that means that there's a bug in the latest update release and I
don't like to change in the system files in order to boot my laptop. So
please fix and let me know when can I revert back what I did and login
normally without the change I made.

Thank you
