[Bug 744812] Re: FontConfig/Qt stack choke on Ubuntu Medium font meta-data (No medium in Inkscape and too bold in Qt apps)

[Michał Sawicz]

I've built patched packages in ppa:saviq/testing, you can first:

$ sudo apt-get install ttf-ubuntu-font-family

to get the Medium fonts back, and see how that affects Qt apps.

Then, upgrade Qt with packages from my ppa:

$ sudo apt-get upgrade

And the results:

Bug description:
  [Kubuntu natty up-to-date]
  Hi,
  Without any change on my system, I noticed some days ago that my default font (ubuntu) changed. Some odd behaviour appeared : ubuntu medium 10 pt was ok but ubuntu medium 11pt was bold (-> in my taskbar clock or in kpackapgekit). In fact, after some play with kcm kubuntu font manager, the ubuntu medium 10pt was wrong, since kcm module shows the true appearance of ubuntu medium, which is quite bold. I swapped to ubunu light font
  SO ! I changed font hinting to light (default in kubuntu seems to be medium) and it seems to have solved bugs.
  Anyway, "ubuntu font" management by KDE seems to be strange, and firefox 4 font rendering is worse (imho) with light hinting (but maybe because of unselected "system default" parameter in fonts kcm).
