Per Bug #861683, xserver-xorg-legacy is a "recommend" for xserver-xorg, and as such, is likely to be installed by default. Section 2.2.10 of the Debian Stretch Release Notes indicates that Xorg will now run as a non-root user for most setups, indicating 3 requirements for this to function correctly. However, there is no mention of the need to remove xserver-xorg-legacy. The Releases Notes currently indicate that Xorg will run as a regular user if:
1) logind and libpam-systemd are installed 2) The system supports Kernel Mode Setting 3) GDM3 is used as the display manager (if X is started from the DM) However, after spending 30 minutes trying to figure out why a newly installed Debian Stretch system refused to start Xorg as a regular user, I realized it was *also* necessary to remove xserver-xorg-legacy (I didn't realize this package was installed). This is not documented in the Release Notes or at https://wiki.debian.org/Xorg. Rather, the release notes gives the strong impression that the aforementioned items are sufficient to ensure Xorg will not run as root. I replied to Bug # 861683 but the mail bounced back as this bug is now archived. My question is how do I go about requesting that the Release Notes be updated to make this issue more clear to new users.
