Tracking down the elusive lightdm-webkit-greeter bug

[newtusmaximus]

Took upgrade route to 2.4 from 2.0 on desktop.  been running fine everyday use for a few weeks.  Today the "greeter" raised it head and refuses to close. Minimised.  Screen running on default  desktop settings.  Updates done weekly.

When this happens, please check the logs in /var/log/lightdm/
also kernel messages

Code:

cat /var/log/dmesg

I wonder if it has to do with the certain hardware like graphic cards or just because of some configuration.

Whilst making changes to the new login screen, I noticed in the /usr/share/lightdm-webkit/themes/linuxlite/index.theme file the following line was:

Code:

session=gnome

So I changed it to:

Code:

session=xfce4

and it seems to have done no harm. I've made this change on my main system as well as in VB.
I am hoping that this is the cause of the occasional time where you login and the webkit-greeter window appears and you have to close it.
If you'd like to jump on the 'test that theory bandwagon' please feel free and let me know how you get on

Jerry,
I've set it to

Code:

session=xfce

because session deskop file is named xfce.desktop

Code:

ls /usr/share/xsessions/
xfce.desktop

This never happens to me. Maybe I've changed something else too.
Here is my full conf:

Code:

Thanks for sharing your file contents misko. We tried setting session=xfce and it still occurs completely at random. I'd actually like to use gdm given its support and theming but the list of deps it pulls in is crazy!
