Lost anti-aliasing

Hi all,

On a newly installed machine with Ubuntu 12.04.03 I have lost the capability to display the fonts anti-aliased with root 5.34.10:

I do have XFT enable during configuring
I do have a libGX11TTF.so.5.34 file
root-config --features says I have "xft"
I do have set to use Xft in two places:
(1) X11.UseXft: yes
(2) gEnv->SetValue(“X11.UseXft”, “true”);

I do have set to use TTF fonts:
.rootrc:# Path where to look for TrueType fonts.
.rootrc:Unix..Root.UseTTFonts: true
..Root.TTFontPath: $(ROOTSYS)/fonts
.rootrc:Gui.DefaultFont: -
.rootrc:Gui.MenuFont: -
.rootrc:Gui.MenuHiFont: -
.rootrc:Gui.DocFixedFont: -
.rootrc:Gui.DocPropFont: -
.rootrc:Gui.IconFont: -
.rootrc:Gui.StatusFont: -

I do have 34 fonts in the ROOT font directory…

The guitest example also does not have smoothed fonts.

Has anybody any clue how I could get anti-aliasing back?


Hi Andreas,

See for example [url=https://root-forum.cern.ch/t/adobe-helvetica-on-ubuntu-11-04/12319/1 thread[/url] and [url=https://root-forum.cern.ch/t/x11-fonts-under-kubuntu-12-04/15584/1 one[/url], they may help

Cheers, Bertrand.

Hi Betrand,

sudo apt-get install t1-xfree86-nonfree ttf-xfree86-nonfree ttf-xfree86-nonfree-syriac xfonts-75dpi xfonts-100dpi xfs xfstt libXft-dev libXext-dev python python-dev gcc g++ make binutils libx11-dev libxpm-dev libxft-dev libxext-dev build-essential
(Most of the things were already installed!)
Recompile ROOT


Thanks a lot,
