To start the +Xorg X server with these rights your system is using a suid root wrapper +installed as __suid_wrapper_dir__/Xorg.wrap which will execute the real +X server which is installed as __suid_wrapper_dir__/Xorg.bin . +.PP +By default Xorg.wrap will autodetect if root rights are necessary, and +if not it will drop its elevated rights before starting the real X server. +By default Xorg.wrap will only allow executing the real X server from login +sessions on a physical console. + +.SH CONFIG FILE +Xorg.wrap's default behavior can be overridden from the +\fI__sysconfdir__/X11/Xwrapper.config\fP config file. Lines starting with a +\fB#\fP in Xwrapper.config are considered comments and will be ignored. Any +other non empty lines must take the form of \fBkey\fP = \fIvalue\fP. +.TP 8 +\fBallowed_users\fP = \fIrootonly\fP|\fIconsole\fP|\fIanybody\fP +Specify which users may start the X server through the wrapper. Use +\fIrootonly\fP to only allow root, use \fIconsole\fP to only allow users +logged into a physical console, and use \fIanybody\fP to allow anybody. +The default is \fIconsole\fP. +.TP 8 +\fBneeds_root_rights\fP = \fIyes\fP|\fIno\fP|\fIauto\fP +Configure if the wrapper should drop its elevated (root) rights before starting +the X server. Use \fIyes\fP to force execution as root, \fIno\fP to force +execution with all suid rights dropped, and \fIauto\fP to letter the wrapper +auto-detect. The default is \fIauto\fP. +.PP +When auto-detecting the wrapper will drop rights if kms graphics are available +and not drop them if no kms graphics are detected. If a system has multiple +graphics cards and some are not kms capable auto-detection may fail, +in this case manual configuration should be used. + +.SH "SEE ALSO" +Xorg X server information: \fIXorg\fP(1) |
