"window->screen()->physicalDotsPerInch() / 25.4" may be negative on

Status
Invalid for Mir. Unless you can show Mir returning bad data using the
'mirout' command or such.
Mir will indeed have some DisplayConfigurationOutput structures whose
contents are not fully populated. However QtMir should be ignoring those
structures on the basis of the 'used' and 'connected' flags
I'd say error of negative values is when running under xvfb, we just
workarounded that in unity8 version of that code, so probably not a mir
problem?

It appears QScreen.physicalDotsPerInch for Mir is implemented in QtMir:
void Screen::setMirDisplayConfiguration(const
mir::graphics::DisplayConfigurationOutput &screen)

m_physicalSize.setWidth(screen.physical_size_mm.width.as_float());
m_physicalSize.setH

Or (possibility #3) comment #1 might be wrong and maybe Qt gets the DPI
from the new DPI events, and fails.

I've been testing and trying to reproduce this issue, including hacking
'mirout' so it works with unity8.
In all cases I only see valid positive numbers for the physical display
dimensions. So this bug is either nothing to do with Mir, or some
device-specific problem. What device do you see the pr
Found the aforementioned expression in the unity8 source. Of course the
data comes from Mir still.

Qtubuntu reads the physical display size from Mir's
DisplayConfiguration. That is then used by Qt to calculate
physicalDotsPerInch().
