Hello,
first of all... shame on me ! I didn't search the forum before posting... too bad.
Now, it's time for explanations. When I do 'tail -f /var/log/XFree86.0.log' :
FreeType: couldn't open face /usr/share/fonts/truetype/Arial_Bold_Italic.ttf: 1
So, I get the package 'msttcorefonts' which contains some Microsoft's fonts. Everything goes fine and directory 'msttcorefonts' was created in /usr/share/fonts/truetype/ . I edited my X configuration's file and restarted it. But I get the same message... I decided to softlink all the fonts from /usr/share/fonts/truetype/msttcorefonts to the directory /usr/share/fonts/truetype/
And now aMule works again !!
I got some font problem with Mplayer... and my ugly trick also solve it. Maybe some Debian's upgrades broke something ! or not... ?(
Thanks again for all your work and perfect support !
Best regards,
Thoseg
