Problem with fonts

Dear ROOTers,

I have moved from ROOT v5.20 to v5.22 at ccali-in2p3, configuring it with:

setenv ROOTSYS /usr/local/root/root_v5.22.00/root
setenv LD_LIBRARY_PATH /usr/local/root/root_v5.22.00/root/lib/root/
setenv PATH ${ROOTSYS}/bin:${PATH}
setenv PATH ${ROOTSYS}/lib:${PATH}

When openning ROOT, I get:

Couldn't find font "-adobe-helvetica-medium-r-*-*-10-*-*-*-*-*-iso8859-1",
trying "fixed". Please fix your system so helvetica can be found, 
this font typically is in the rpm (or pkg equivalent) package 
XFree86-[75,100]dpi-fonts or fonts-xorg-[75,100]dpi.

and if I try to draw an histo I get the following error:

Warning in <TAttText::Modify>: cannot find the right size font

which is surely related,

do you have an idea where that may come from ?

Thanks,

Xavier

In $ROOTSYS/etc/system.rootrc , is X11.UseXft set to “yes” in your case ?
can you check (may be it is not the problem anyway…)

Is the font server (xfs) running on your machine ? (ps -aef | grep xfs)

You said you get this error when you try to plot something. By default root uses the freetype fonts. so it should not load the X11 fonts (for plotting at least) . Did you request ROOT to use explicitly X11 fonts ?
