https://wiki.gentoo.org/wiki/Non_root_Xorg http://lists.x.org/archives/xorg-devel/2010-June/010511.html 'Kernel mode-setting' really just adds interfaces to the kernel which enables userspace software to request that some 'graphics card' is programmed/ configured in order to do XXX, as opposed to 'the userspace software' (aka 'the X server') accessing the hardware directly in order to do this. As far as I can tell, systemd only comes into play here in order to change 'device node access permissions' automatically and (indirectly) relies on KMS itself. BTW: Considering that X has worked 'as root' for over 20 years and the sky didn't fall, why's that suddenly a serious problem? Especially nowadays, where 'devices running an X server and used by "untrusted users"' are virtually extinct? _______________________________________________ Dng mailing list [email protected] https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
