Unity/control center: Wrong text-scale-factor at session init

[Jorge Juan]

My laptop is a Dell XPS 13 9333. It came with Ubuntu 12.04 installed. I updated to 14.04 without problem. I removed the obsolete/local packages inherited from the Dell repositories. Everything seems to work fine (except for the bug reported here).

I have the menu and title bar scale in control center -> display set to 1.25. It works fine most of the time but some times, when I start a session text size is much bigger than normal. Using gsettings I see that:

xps:~$ gsettings get com.canonical.Unity.Interface text-scale-factor
1.953125
xps:~$ gsettings get org.gnome.desktop.interface text-scaling-factor
2.44140625
xps:~$ gsettings get org.gnome.desktop.interface scaling-factor
uint32 1

It seems that text-scaling-factor = "menu and title bar scale" * text-scale-factor.

I do not see a way to change com.canonical.Unity.Interface->text-scale-factor from the interface.

Manually setting text-scale-factor to 1 solves the problem inmediatry except from some text misalignment in the dash that is corrected aftere a session restart:

xps:~$ gsettings set com.canonical.Unity.Interface text-scale-factor 1
xps:~$ gsettings get com.canonical.Unity.Interface text-scale-factor
1.0

I use it as a workaround.

I report the bug in unity-control-center becouse it is there where the relevant desktop option can be acceced but the problem is most probably related to unity session start.

unity is tweaking those factors on start, reassigning to it
