When I used Fedora FC3 yesterday, GDM suddenly didn't come, I have been helping for a long time. Today, I saw it, and I suddenly found that GDM and Fontconfig conflicts. When SIMSUN is configured in /etc/fonts/fonts.conf, GDM cannot be started after SIMSUN's alternative font. Conflict configuration is:
Sans-Serif
Luxi Sans
Albany AMT
BitStream Vera Sans
Verdana
NIMBUS SANS L
Arial
Helvetica
Kacstqura
Nachlieli CLM
Lohit Bengali
Lohit Gujarati
Lohit Hindi
Lohit Punjabi
Lohit Tamil
Kochi Gothic
Zysong18030
SIMSUN
AR PL SUNGTIL GB
Ar Pl Mingti2L Big5
Baekmuk Gulim
SIMSUN
Similar configurations are not allowed. It's ok after shielding. However, this configuration is very important, which will automatically use SIMSUN in GNOME to display Chinese. Also intend to study how to configure Fontconfig, so that SIMSUN can display the black body.
