My redhat9.0 suddently can't boot into Xwindows mode while working normally before now. I don't remember I had changed any configuration files. The wrong messages it printed: "fatal error: cant't open the cursor font "cursor"". but when i reboot and in rescure mode it can work perfectly. how did this happen? then what can i do ? I hate to restore operating system for its long installation time , up to three hours last time. Any help will be appropreciate.
