I have a bunch of files on /etc/X11 XF86Config-4 HAS a DRI section, mode=666. XF86Config Does not. The file backed up by the script dialog that I aborted is a copy of the -4 file XF86Config-4.debconf. There is also XF86COnfig.in, -4.in, -4.kxconfi.backup:q All of the -4 files have a DRI section. They also have 1187 line modes, etc.
