Bug#814394: xserver-xorg-legacy: Fails to start xserver after upgrade to 1.18.1

I haven't noticed that recommendation before. I run `apt-rdepends xserver-xorg' without any other options and noticed that systemd is not a dependency. But since it is only a recommendation, I assume you allow such configurations when the recommended package is missing. Link you sent previously contains reference to #814313, which shows that I am not the only one who have such unusual configuration. > While this could be changed into a Depends, it would probably not really > make you happy.

I installed xserver-xorg-legacy for its - let me quote the short description - "setuid root Xorg server wrapper". It is really surprising to hear that the wrapper drops the root privileges is some situations. Probably this fact should be better announced - maybe in the package's description or via README.Debian. Or maybe would it be possible to add some reference to the `needs_root_rights' variable into /etc/X11/Xwrapper.config during initial installation or upgrade of the package? Finally - as I suggested in the retitle line - maybe the wrapper could check for working systemd-login before dropping root privileges. Anyway, with `needs_root_rights=yes' I was able to upgrade the package to the latest version and it works! Thanks a lot, robert

The xserver-xorg-core package recommends libpam-systemd for a reason.

There is a change in behavior in 1.18.1, but it is actually a bugfix. According to the Xwrapper.config(5) manpage , | needs_root_rights = yes|no|auto | Configure if the wrapper should drop its elevated (root) | rights before starting the X server. Use yes to force exe‐ | cution as root, no to force execution with all suid rights | dropped, and auto to let the wrapper auto-detect. The | default is auto. | | 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 capa‐ | ble auto-detection may fail, in this case manual configuration | should be used. ` Now, the bug is that the kms detection did not actually work[1] and so the wrapper never dropped root rights, contrary to what the manpage says. This is fixed in xserver 1.18.1, and so you now need "needs_root_rights = yes" in /etc/X11/Xwrapper.config if you don't want to install libpam-systemd (or a display manager that starts X as root).

Which dependencies? xserver-xorg *does not* depend on systemd xserver-xorg-legacy *does not* depend on systemd either (to be honest it does not even depend on xserver-xorg...) Previous version of xserver-xorg-legacy worked without systemd. My system is pretty workable without systemd (I removed the equiv-generated packages yesterday). Believe or not, I am writing this email in icedove, which is running on X from xserver-xorg 1:7.7+13 & xserver-xorg-legacy 2:1.18.0-3. packages. Regards, robert

I had dummy systemd and libpam-systemd created by equiv (to make few packages like gnome-settings-demon or lokalize happy), however I've just removed them: /home/robert> LC_ALL=C dpkg -l *systemd* Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version ArchitectureDescription +++--===-===-== un libpam-systemd (no description available) ii libsystemd0:i386 229-1 i386systemd utility library un systemd (no description available) un systemd-sysv (no description available) (Unfortunately I couldn't remove libsystemd0, because more packages depend on it, including xserver packages).

It's not supposed to, when using the X wrapper and needs_root_rights=yes. There used to be an upstream patch that even allowed X to start without this, and skip the ioperm check (it's not actually needed with KMS), which Debian dropped, because I guess they want to require everyone to use systemd. However, even with needs_root_rights, startup broke for me recently as well, I had to install systemd-logind temporarily until I can switch to a distro which doesn't force me to run systemd stuff. Even with systemd-logind installed, you still have to invoke it on the same tty you run X on, even with needs_root_rights=yes, it won't change the perms for you. This, too, worked fine for me up until a month or so ago. I think the solution is to just use a distro which does not require systemd, such as Gentoo. Debian's X maintainers do not appear to be interested in making X work without systemd, as it has for the last 30 years or so...
