Description of problem: Lightdm does not show user image which is created from KDE password & user account settings dialog. I believe this image is stored in the users home directory as .face.icon - instead a default image is used. I also saw Bug 911826 which was related to lightdm-gtk - and it mentions kde in passing, it talks about F19, so not sure if it is a match. I did a google search and found postings which mention this problem in other distributions. Suggestions range from copying .face.icon to .face to changing the permissions of the file. None work. Version-Release number of selected component (if applicable): lightdm-kde-0.3.0-2.fc18.x86_64 How reproducible: Activate lightdm and either reboot system or logoff userid. Default image is shown. Steps to Reproduce: 1. Create user image using KDE user & account settings dialog 2. Activate lightdm using display-manager switcher 3. Reboot or logoff userid Actual results: Default image is shown Expected results: User image is shown Additional info:
I upgraded to the following from the testing repository: lightdm-qt-1.4.1-3.fc18.x86_64 lightdm-kde-0.3.2.1-1.fc18.x86_64 lightdm-1.4.1-3.fc18.x86_64 lightdm-gobject-1.4.1-3.fc18.x86_64 Additionally I created the .face file in my home directory some google searches suggest as follows: ln -s .face.icon .face Same issue, doesn't work.
Works for me, testing with those same versions, *if* you change default home directory permissions to allow other users' access to your $HOME : chmod o+x $HOME
In particular, the 'lightdm' user, must have adequate permissions to read your $HOME/.face (or $HOME/.face.icon)
is there some way to make this 'just works'? (besides running lightdm as root)
ah I think we're supposed to utilize accountsservice. You can set an icon file using it's dbus interface. It puts the file in /var/lib/AccountsService/icons/ now lightdm-kde shows the proper icon file, even without read access to $HOME. surprised this works...
Ah, we can consider modifying KDE Password & User Account Setting module: 1. add support to KDE Password & User Account Setting to use this accountsservice dbus interface and/or 2. adding code to the KDE Password & User Account Settings module to check-for and fix $HOME permissions when setting a custom $HOME/.face.icon (for legacy DM's that don't yet support accountsservice, like kdm)

Thanks for the heads up. I didn't want to change my permissions, so I logged into Gnome, went to account settings, clicked on the default avatar, and assigned a photo. Then logged off, and lo and behold... there is my photo in lightdm. Amazing...LOL... At least we have two simple workarounds... Thanks!
(In reply to comment #6) > 2. adding code to the KDE Password & User Account Settings module to > check-for and fix $HOME permissions when setting a custom $HOME/.face.icon > (for legacy DM's that don't yet support accountsservice, like kdm) Though that sound dangerous to me. User management tools shouldn't silently relax $HOME permissions...
And it shouldn't be needed for KDM because KDM always runs as root.
adjusting summary, I'll see if I can whip up some basic proof-of-concept code to support this today.
any progress rex? Suppose I can finish this as well.
Turns out to do this right was a wee bit more than trivial (but not *hard*), so no, nothing to report yet. @work has kept my free/play time at a minimum for the foreseeable future, so no eta either. sorry.
allright I'm going to take it then
yeah wasn't too hard. see here for a working solution: https://git.reviewboard.kde.org/r/110875/
Good work, thanks! Let's see what upstream thinks of the patch, but IMHO it's definitely good enough for us.
Thanks, I tried building your submitted reviewboard patch on f19, and ran into a problem. Seems qdbusxml2cpp chokes on /usr/share/dbus-1/interfaces/org.freedesktop.Accounts.User.xml : Got unknown type `a(xxa{sv})' on f19, the problematic xml snippet looks like: <property name="LoginHistory" type="a(xxa{sv})" access="read"> <doc:doc> <doc:description> <doc:para> The login history for this user. Each entry in the array represents a login session. The first two members are the login time and logout time, as timestamps (seconds since the epoch). If the session is still running, the logout time is 0. </doc:para> ... which may indeed be a newer/complex type that qt4's dbus code doesn't handle (yet).
(In reply to Rex Dieter from comment #18) > which may indeed be a newer/complex type that qt4's dbus code doesn't handle > (yet). And it never will be able to. But what we could do is annotate the xml and teach Qt about the custom array type [1]. Dunno if thats ok with the accountsservice guys. [1] http://techbase.kde.org/Development/Tutorials/D-Bus/CustomTypes#Edit_the_XML
It's not only OK but required for Qt to work with such complex types; another side of the story is that you have to add custom marshall/demarshall[1] methods should you want to actually use the function in question. http://qt-project.org/doc/qt-4.8/qdbusargument.html
I'd be happy to reach out to accountsservice maintainers and help apply fixes/patches to the xml as needed.
