Package: wdm Version: 1.28-17 Severity: wishlist Since the following information is helpful when a .service file for wdm is created, but #761236 is already closed, I'm creating a new bug report tracking this.
Here's the mail, Agustin kindly sent to #761236: ----- Forwarded message from Agustin Martin <[email protected]> ----- Date: Mon, 15 Sep 2014 12:14:07 +0200 From: Agustin Martin <[email protected]> To: Eliad Bagherzadegan <[email protected]>, [email protected], [email protected] Subject: Bug#761236: wdm does not work with systemd as the init system Control: tag 748668 +patch 2014-09-13 10:46 GMT+02:00 Axel Beckert <[email protected]>: > Control: affects 748668 wdm > Control: severity 748668 important > > Hi Eliad, > > Eliad Bagherzadegan wrote: >> On 09/12/2014 02:04 PM, Agustin Martin wrote: >> > I guess that if you remove slim wdm will work again. >> >> Thank you.

Hi, Axel, Sorry, I forgot to mark this bug report as affecting wdm, thanks for doing. IIRC, last time I looked about how other display managers deal with this I found no info. I later switched back to sysv until I can make two local services behave exactly as I want under systemd, so forgot about this until now. However seems that more info is now available, some of it from the gnome folks. There are service files for at least gnome3 and lightdm. lightdm is probably closer to slim (and wdm) needs and the most useful place to look at. References for the bug reports, https://bugs.debian.org/733220 Also info available in https://titanpad.com/s-gsprintchangelog section "= default display manager selection =" In short they suggest using something like ExecStartPre=/bin/sh -c '[ ! -f /etc/X11/default-display-manager -o "$(cat /etc/X11/default-display-manager 2>/dev/null)" = "/usr/sbin/lightdm" ]' but there are some other details like symlinks and aliases discouraging to care about. >From titanpad: * /etc/X11/default-display-manager is and remains the definitive selection * graphical.target has Wants=display-manager.service which provides the dependency for auto-starting DM * In DM packages' .service files: Don't have an [Install] section (Dependency or Alias) as systemctl enable will otherwise make the last installed package "win" instead of the one selected in debconf * DM postinst: Create symlink /etc/systemd/system/display-manager.service → /lib/systemd/system/$(basename $(cat /e/X/d)).service * Until all DM .services are converted: Add ExecStartPre= check that /e/X/d is pointing to "me", and fail otherwise I think that might be useful for fixing slim and for the future implementation of a wdm.service file.
