lightdm-tiny-greeter's Issues

failed to start session

when i go to login it says failed to start session and im unsure of how to fix it

as far as I know, gtk3 is wayland-ready, isn't it? Yet, I did not find anything in the readme about whether this has been tested with wayland, is compatible with wayland (or whether wayland is out of scope, which would also be okay for me).

Would be nice if you could add a short disclaimer/note about wayland support.

Can't start X session

Hello!
Although usual lightdm works fine, I can't log in with lightdm-tiny-greeter. After every attempt login screen just appear again.
In my /usr/share/xsession I have only:
bspwm.desktop
In config.h I have this line:
static const char *session = "bspwm";
The only thing I have in my /var/log/lightdm/seat0-greeter.log is:
** (process:847): WARNING **: 16:51:52.046: Failed to open CK session: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ConsoleKit was not provided by any .service files
I will appreciate any help.

CSS not loading?

I'm having a weird problem and I'm not sure where the responsibility lies. When my computer starts, X spins up, lightdm is spawned, and this greeter starts but I'm unable to see anything that should be in white. I use this greeter on one laptop without problems. I'm trying it on a different laptop and this problem crops up. I can see the cursor blinking and I can authenticate and login. However, graphically I'm "flying blind".

I've recorded a video (on my phone...) that demonstrates this problem. Notably, this problem can be fixed for a single login round by systemctl restart display-manager.service. However, logging out after this results in the same problem until the service is restarted again (killing all pre-existing sessions).

Any ideas whose responsibility this is and how I might fix it?

Please note that I've already added the below to lightdm.conf

logind-check-graphical = true

Greeter won't start, scarce logging.

here's the contents of lightdm.log, the seat0 log is supposed to have logging from the greeter right? It's empty so this is all I have, not sure what else I should really report on this.
My system is Void so no systemd, just runit if that might be an issue.

Default User Patch

This isn't really an issue, but not sure where else to add this :P

I've created a patch for this (since it is the suckless way :P) to enable a default user...
(i.e prefilling the username box on login)

there's a new prop in config.h called default_user, just set that to a username and presto, no need to type a username anymore as it will be prefilled, just hit enter and type the password :P

If anybody is interested here it is

Linking error

When using make I got a lot of undefined reference errors.
After fiddleing and googleing a lot, I discovered that changing the order in the build part of the Makefile (moving $(LIBS) to the end of the line, so that they become the last arguments, not the first) resolved my issue.
Not sure what's happening, didn't look that much into it, but a source that gave me this idea mentions that new gcc versions are more strict about argument order.
I'm quite new to git and github, don't know if this is the apropriate place for this.

show password prompt one more time if password was mistyped

I get that this might sound bold but hear me out.
All login prompts I am familiar with, operate on the same basis.

type in username
type in password
enter
if username and password match profit
if password is not correct ask the user to reenter the password

If you mistype your password you are asked to reenter your password at least once, until some escalation takes place.
With this greeter it is possible for people to leak their passwords due to the fact that a mistyped password results in a new username field which shows characters in plaintext.
