Having the ability to diagnose the X.Org problem within the fail-safe mode is very nice to see. In earlier releases the user would either need to diagnose the Xorg.0.log.old once reconfiguring the xorg.conf with displayconfig-gtk or disable the FailSafeXServer within the gdm.conf. When the user chooses to troubleshoot the error they have the option of reviewing the X server logo, reviewing the start-up errors, or editing the configuration file.
Reviewing the X server and startup logs will launch the text files within gedit. The standard GNOME text editor is loaded within the FailSafeXServer outside of GNOME and without a window manager. Once quitting gedit, they return to the FaileSafeXServer prompts. When choosing to edit the configuration file, the xorg.conf.failsafe is opened within gedit.
