arctica-greeter does not honor gsettings changes

[Bill (franksmcb)]

Ubuntu MATE 20.10 daily iso

Expected result:
Change login background
Change settings in: org>ArcticaProject>arctica-greeter>background
Change login backgroud to /usr/share/backgrounds/ubuntu-mate-common/Grey-Wall.png

Actual result:
Login background does not change to reflect gsettings changes
Login background remains as default value.

Editing /etc/lightdm/lightdm.conf.d/90-arctica-greeter.conf does not change settings.

Status changed to 'Confirmed' because the bug affects multiple users.

Just to add that editing schema file from dconf-editor as suggested in the release notes (https://ubuntu-mate.org/blog/ubuntu-mate-groovy-gorilla-release-notes/) also does not work.

[ironfoot (ironfoot)]

Editing /usr/share/glib-2.0/schemas/30_ubuntu-mate.gschema.override works.
You have to recompile schemas after editing: sudo glib-compile-schemas /usr/share/glib-2.0/schemas/.

[Sai Vinoba (saivinob)]

While this may work (I did not try tbh), it is not an ideal solution. The greeter should reflect changes done via gsettings/dconf-editor.

Also, as I checked today, this is not specific to Ubuntu MATE. Same issue exists in LinuxMint when arctica-greeter is installed and enabled. I raised an issue on github. Ref: https://github.com/ArcticaProject/arctica-greeter/issues/17

The correct verbiage, for schema override in file 30_ubuntu-mate.gschema.override, line 6: enable-hidpi='on' and I also change onboard from auto to = true as well under the Arctica section for good measure. Then run the command to update the schema as Ironfoot states in #5.

For anyone seeing later, the Github comment in comment #6 by Sai has been closed as "works as intended." I could not run dfcon-editor as lightdm user using several command methods so I had to revert back to the schema override per #5.

Arctica defaulted back to super high resolution after the beta release update of 21.04 today. I was once again shown a super tiny login on boot (onboard buttons are less than 1cm square, smaller than my pinky finger nail). Its VERY difficult to login on touch devices/tablets without a physical keyboard. I have performed: "sudo glib-compile-schemas /usr/share/glib-2.0/schemas/" for a third time now. This doesn't stick across updates, is a temp work around, not a permanent fix. Please advise.

[ironfoot (ironfoot)]

It is expected that updates may overwrite system files. Try creating your own gschema.override file (for example, /usr/share/glib-2.0/schemas/40_arctica-greeter.gschema.override) and put arctica section header and your changes there. Then recompile schemas.

[chris (gripfastistech)]

Thanks Irongfoot for the tip. I've created the file as suggested.
Today, the greeter was normal but its been weeks since I booted the
device. Hope it sticks.

Still an issue with 21.10

Still a bug in 22.04 LTS. I'm running Ubuntu Mate.
