White screen on lightdm-webkit2-greeter

Hi all

Yesterday lightdm was working fine using the lightdm-webkit2-greeter. Today I get a white screen on login so I had to use another greeter.

Any idea what could cause this? I don't see anything in the upgrade list between the working and not working times.

GTK greeter also goes white on the second screen after login briefly. Not sure if its related...

Just so you know I fixed my issue by upgrading to Kernel 4.5, doubt its the same thing as yours but worth a shot

Hi,

Sorry to bring this up again, but I'm facing the exact same issue.
Happy to switch to any other greeter, if this resolves the issue. I'm currently on a tty, so I'd appreciate any help on how to switch the greeter from the command line...

There's probably a specific config for that?
Which greeter should I use instead of the lightdm greeter?

Thank you!

Hi,

additional info:
when I'm in a tty and run "startx" my DE loads...

is there anything to bypass this problem or to fix it in general? It seems to have broken with the last major KDE plasma update on June 14th.....

It is very unlikely for a plasma update to have broken this...

The webkit greeter is available from the AUR you might want to  try to rebuild it and see if that helps, or switch to a different greeter https://wiki.archlinux.org/index.php/LightDM#Greeter

My KDE greeter also went completely white today, from a recent update. lwebkit2 greeter with antergos also did not work, as no input fields or buttons were visible in the center. Changing the webkit2 theme to simple allowed me to login.

Edit file /etc/lightdm/lightdm-webkit2-greeter.conf
Change webkit-theme to simple. So that it looks like;

[greeter]
webkit-theme = simple

Re: White screen on lightdm-webkit2-greeter

Same here, trying to make buggy LightDM less buggy. Pawh's workaround helped; thanks, Pawh. As you probably know, the KDE greeter shows the white screen too. A similar workaround works for it. ? Change in "/etc/lightdm/lightdm-kde-greeter.conf":

[greeter]
theme-name=userbar

Themes reside in "/usr/share/apps/lightdm-kde-greeter/themes".

This worked for me as well; just did a fresh install with plasma, xorg, lightdm & lightdm-kde-greeter, had to change this to not just get the white screen.
