In order to make the change build-able on Trusty, we need to add new
interface into cairo.vapi:

--- vala-0.22-0.22.1.orig/vapi/cairo.vapi
+++ vala-0.22-0.22.1/vapi/cairo.vapi
@@ -645,6 +645,8 @@ namespace Cairo {
public void mark_dirty_rectangle (int x, int y, int width, int 
height);
public void set_device_offset (double x_offset, double 
y_offset);
public void get_device_offset (out double x_offset, out double 
y_offset);
+   public void set_device_scale (double x_scale, double y_scale);
+   public void get_device_scale (out double x_scale, out double 
y_scale);
public void set_fallback_resolution (double x_pixels_per_inch, 
double y_pixels_per_inch);
public void show_page ();
public Status status ();

Those two functions are indeed in Trusty's cairo, so I think it's safe
to expose these interface for Vala.

[Kai-Heng Feng]

Hi Sebastien,

When we enabled OEM products with HiDPI display, the "let's wait before
xsettings settle down" hack was applied [1], so the unity-greeter is
actually scaled to the right resolution, hence this issue.

So it would be great if this fix can be put into Trusty.

[Sebastien Bacher]

Great work Kai, thanks for looking to that bug, the fix seems to work
nicely!

@Artur, why did you nominate for trusty? I don't think we have hidpi
working in that Ubuntu serie at the moment so the bug shouldn't impact
it

[Sebastien Bacher]

Ok, after talking to Shih-Yuan there are still plans to backport some of
the hidpi work to trusty so it might become relevant for that serie,
accepting the nomination
