Disco "check disc for defects" appears not to function

[Erick Brunzell]

Just testing the 20190413.2 image and after selecting "check disc for defects" the Ubuntu splash screen appears very briefly, no testing text is displayed, and a "no errors found" message appears in under one minute.

As recently as 20190326.2 the test ran as expected displaying "scrolling" text on screen before completing and reporting a pass or fail so I doubt this was an intentional change but I could be mistaken.

Indeed, the current experience is confusing, empty screen with a cursor in the top left for a while which looks like it's stuck/not working

It's supposed to use plymouth to display that text. The script that's calling plymouth is in casper (casper-md5check). I'll reassign this bug there, but it may turn out to be elsewhere.

Trying to look but I'm not very familiar with this area so wouldn't decline any help.
