[Daniel van Vugt (vanvugt)]

I think I've seen that unhandled promise in _loadFile in other peoples' logs too, maybe even my own. And it sounds related to a black screen, but nobody else is reporting a black screen!?

[David (roastedtoast)]

The black screen occurs regularly (but not systematically) when I click on "Settings" or sometimes even when I try to change a setting, like Bluetooth or WiFi.
And this error is one of those that appear in the logs.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Daniel van Vugt (vanvugt)]

The log messages seem common so I've made this bug just about them (fixed in 42.1 in theory).

If you still have black screen issues after this reaches 'Fix Released' then please open a new bug.
