Hey Mike, thanks for the update but I'm not sure I get everything. user-background=true seems the default in lightdm-gtk-greeter and relies on the liblightdm api. I couldn't identify at first sight where does LightDM find that user background, but maybe it actually comes from AccountService? If so, swingrock, could you try removing gdm3 and everything else you installed, and just install accountsservice package? And then report back. Regards, >
Bug#1085934: lightdm: No background displayed when user-background = true
Hi, 1st of all, i'm migrating from ubuntu to debian because i'm enough with snap package. Regarding lightdm, my familly would like to see the their background on login screen. It's very usefull for child. I agree that adding gdm3 as dependencies is a very bad idea because it makes me run into many difficulties like having 2 keyboard manager/settings and many other annoying things. But there's something missing in order to have the feature "user backgound" on login screen working. (should be working, it's the default) In order to produce log, i ran : $ sudo apt remove gdm3 $ sudo apt autoremove but lightdm still display backgrounds of users I'm busy this weekend but next week, i'll try to reproduce on a fresh install into virtualbox in order to get logs. regards, Emmanuel On Wed, 23 Oct 2024 16:34:03 +0200 Yves-Alexis Perez wrote: On Wed, 2024-10-23 at 14:34 +0200, swingrock wrote: > * Walkaround > after further analysis, lightdm failed to display the background because > org.gnome.settings-daemon.plugins.background doesn't exist > So i install gdm3 but i keep lightdm as my dm. > and it works but cause so trouble in xfce because of many package such as > keyboard settings and so on were also installed as a part of gdm3 !! > * Excpected solution > It would be nice that the lightdm package contain all nessessary > dependencies in order to have its features working fine. Hey, thank you for the bug report. I'm not sure exactly what are the dependencies of user-background = true (which is the default) but there is no way we would add gdm3 as a dependency to lightdm-gtk-greeter, that wouldn't make sense at all. Also I'm not sure I see the link with org.gnome.settings- daemon.plugins.background but maybe some logs would help. Regards, >
Bug#1085934: lightdm: No background displayed when user-background = true
Hi, Mike said : "So, the solution probably indeed is to add AccountsService under Depends: or Recommends: of lightdm and done with it. " I would like AccountsService to be added under Depends. So that all features were working fine out of the box for light-gtk-greeter. This should be ok for gnome, unity and xfce4. Because it's build for it. For KDE user, most of them use KDM and in case they use lightdm, they would use lightdm-kde-greeter So "AccountsService" should be added only as a Depends of the package : "lightdm-gtk-greeter" regards, Le 25/10/2024 à 10:07, Mike Gabriel a écrit : Control: tag -1 - wontfix Hi Yves, On Fr 25 Okt 2024 09:58:20 CEST, Yves-Alexis Perez wrote: control: tag -1 wontfix On Fri, 2024-10-25 at 07:56 +, Mike Gabriel wrote: So, in a nutshell, without a considerable amount of effort and cooperation from Debian's AccountsService maintainer, this bug report should be tagged as "won't fix" for now. Eh, thanks for the precision. I guess work from both Debian maintainer and upstream. Do you know if they are aware of the patch by the way? - -- Yves-Alexis As Emmanuel tested the whole thing once more, it seems I am mistaken. One more closer look, it seems that LightDM has changed to be more generic and they made the BackgroundFile code (and also the keyboard layout AccountsService attribute) usable on non-Ubuntu distros, as well: See https://github.com/canonical/lightdm/commit/6015bce25f241e7580c03594d846769f8236232f So, the solution probably indeed is to add AccountsService under Depends: or Recommends: of lightdm and done with it. Second part is with the desktop envs then, they need to write the background image file name into the above BackgroundFile attribute in AccountsService, but that's not on us. Obviously, Xfce4 has that feature (as Emmanuel's test worked under Xfce4). Mike

Hi, This is perfectly understandable for users that are aware of what Recommands is. However, even if i know about, i do not have the reflex to look on recommanded packages to in order to made "working" a features that is enabled as defaut. I suggest to disable it as default and add an explanation in the config file that the feature require AccountsSetting. Regards, Emmanuel Le 04/11/2024 à 08:42, Yves-Alexis Perez a écrit : thanks for the suggestion, but we won't do that. AccountsService is a nice add to the lightdm features, but it's in no way necessary, it's not even a basic feature. It's currently in the 'Suggests' field and I think it's just fine that way. Adding it to Recommends would install and run it by default and I don't think we want that at this point.
