I don't know why, I can't start X, INIT: ID "X" Respawning Too Fast: Disabled for 5 minutes to write down the resolution process: find some information,: http://www.unixguide.net/linux/faq/ 09.24.SHTML However, the error is not specifically indicated by x =, so it is not possible to use a method of comment out of the following row. # Run gettys in Standard Runlevels 1: 2345: Respawn: / sbin / mingetty TTY1 2: 2345: Respawn: / sbin / mingetty tty2 3: 2345: Respawn: / sbin / mingetty tty3 4: 2345: Respawn: / sbin / mingetty tty4 5: 2345: Respawn: / sbin / mingetty Tty5 6: 2345: Respawn: / sbin / mingetty TTY6 Viewing the log in / var / log / message, there is no specific illustration where it is wrong. .
