** Description changed:
- A green Xubuntu splash screen with a spinning circle normally appears on
- boot up.
+ [Impact]
+ plymouth has been crashing a whole bunch and notifying users about it.
+
+ [Test Case]
+ We don't have a specific test case but luckily :-( there are thousands of crashes in the Error Tracker about this issue. Subsequently, it should be enough to verify that the new version of plymouth doesn't appear in the following bucket:
+
+ https://errors.ubuntu.com/problem/6aa06f1bc51946c787a01d38e58bc76114555334
+
+ [Regression Potential]
+ The fix has to do with keyboard handling so a possible regression would be the inability to unlock your disks.
+
+ Original Description
+ --------------------
+ A green Xubuntu splash screen with a spinning circle normally appears on boot up.
Now just a blank black screen shows until the login box appears. On
logging in, the desktop appears as normal but an error message pops up
offering to report a bug to developers.
