thanks @rnbdsh, this is really cool, here's my review:

• The implementation is clean and it works very well.
• We should also add support for the additional settings in lightdm-settings.
• The position coordinates are hard to use and don't adapt well to different monitors. That makes it tedious for distributions to set defaults, and tedious also for users using monitors of different resolutions. I'd recommend using enums (i.e. "top-left, top-center, top-right, etc...") instead, and have the greeter calculate the appropriate coordinates based on that, on the resolution, on the presence of a panel, on the size of the logo etc etc..

Waiting on this to get merged :)

Hi, I think what @clefebvre mentioned above needs to be done here:

• Logo: upper-left, upper, upper-right, left, center, right, lower-left, lower, lower-right, maybe default
• Main window alignment: I don't understand why there is an alignment setting as well as x and y positions, why not just have the same positioning method as for the logo - 9 positions

I'm not sure the default logo position is even worthwhile, it's pretty dumb half off the bottom of the screen. (At least that's where it ends up for me) - I'd be ok with doing away with it entirely, but other may not share that opinion.

A couple of other things:

• There's nothing stopping you from positioning stuff entirely out of bounds of the monitor.
• x and y are transposed in the main box offsets (you adjust the y and x moves)

We always have to consider how to present these types of customizations to the user - we'd like to keep this accessible to all users, and it's far easier for everyone to understand simple alignments, and less likely to cause them issues - you prevent them from getting into trouble.

The two respective (logo and main) settings could be strings like previously mentioned - 'upper-left', 'upper-right', etc...

• The main window alignment, you should probably keep using the GtkAlignment positioning, since the absolute size of this may not be very well-defined - you could just use 0, .5, 1 for both directions.
• The logo size you'd need to do some calculations based on the image and monitor size, but since both are well-defined, it wouldn't be complicated.

Sorry for the length - we would like to see this get in. If you need any guidance or assistance don't hesitate to ask.

Thanks

The original post was from ~1 year ago, and I currently don't have time to get into GTK/vala again.

I initially tried something like this 9-position variant but GtkAlignment didn't behave the way i expected, that's why I chose the X/Y method.

I'm going to close this for now then. If there is additional interest down the road we can revisit.

Not sure of the etiquette here as I'm new to github but I was trying to work out how to position the login window, because the default placement conflicts with features of the backgrounds I've chosen, and found this thread; just like to express my interest in this feature being made available. Thank you!
