Fixed 'prepend' terminology in comments, restored old loop as it seems to work for me now in overwriting the file as one overall multiline instead of overwriting the file with each line at a time, code simplification based on review comments... credits-adding will come in the next commit.
This change fixes a few issues and adds a few improvements to the LightDM Autologin configuration process:
Fixes:
- Fixes malforming of configuration file out of the box, as without `[SeatDefaults]`, `[Seat:*]` or similar in the configuration file LightDM will break on a lot of distributions using LightDM
- Preserves the intended lightdm.conf file settings outside of `autologin-user` if the distribution has an /etc/lightdm/lightdm.conf file of its own
Misc. changes:
- Small spelling fix
- If a distro provides an install-scenario that doesn't provide a DM,
(e.g. via netinstall) then that should be ok; if there **is** a DM
it should be configured.
FIXES: #1095
- The parameter list was wrong, and could never have worked
(apparently noone mixes LightDM with basic setup, even though
it's one of the few with basic_setup()).
- Shorten some lines.
- Move variable initializations closer to where they are first used
- Also warn if no implementations are available
- Handle sysconfig as any other DM; there's no real reason
to treat it specially.
- Add (empty) implementations of all the abstract methods that
are not needed (or supported) by various DMs.
- Order the abstract methods by calling order
- Fix up have_dm
- Make root_mount_point a parameter of the DM classes
- Create instances as needed, then check if they're available
- Keep instances that actually need to be configured
- Clean up remaining cruft from removing old setup_autologin()
with all the string-comparison magic.
- Some DMs allow setting up the default DE. Factor that
out into a method like basic_setup() and setup_autologin()
and add it to the configuration chain.
- For all the DMs that have some kind of basic setup,
introduce a method in the DM class for doing just that.
- The Python code now doesn't call basic setup anywhere,
so this specific revision isn't going to work properly.
- Split the entire body of setup_autologin() to a method
per implementation class.
- Make the check for presence of a DM a class-method,
since if it fails, instantiation is going to be useless.
If displaymanagers is not set in the job config or globally,
it wasn't set at all, leading to a runtime error. Set to
None, so that the regular error message will be triggered.
FIXES#1002
- no matter if for example slick-greeter is installed as "lightdm-slick-greeter" or whatever.
tested with lightdm-deepin-greeter and slick-greeter.
- plus some little simplifications
- added Copyright

Since sddm.conf follows the INI format we can use configparser
with a few added options to properly parse the config and write
it out instead of manually parsing each line which is slow and
prone to error.
For eg. The old code would fail to parse a conf which had no
commented out User key but where the user had configured autologin
in Calamares.
