[SOLVED] LightDM & WebKit greeter: temporary time-outs during start

MilanKnizek · 2015-06-20 09:09:44

Hello,

I am trying to figure out what is causing the webkit greeter to time outs. (It takes about 11 seconds do display the greeter.)

The lightdm.log reads:

It is probably related to webkit (or one of its dependencies), since with the gtk greeter this does not happen. I had a similar temporary freeze with html themes for MDM (Mate DM).

I was not able to find out what actually searches for /usr/lib/nspluginwrapper/i386/linux/npviewer. After installing nsplugginwrapper, the log got extended with search messages for ICA client... Might be some old configuration files? But where?

I have the following versions of lightdm and webkit related packages:

    A lightweight display manager
community/lightdm-gtk-greeter 1:2.0.1-2
    GTK+ greeter for LightDM
local/lightdm-webkit-greeter 0.1.2-6
    A lightweight display manager
local/lightdm-webkit-theme-userdock 1.0.2-1

    Classes for a WebKit2 based implementation and a new QML API
extra/qtwebkit 2.3.4-2
    An open source web browser engine (Qt port)

Ok, solved now.

I had an obsolete ICA client "so" file in /usr/lib/mozilla/plugins dir, which required nspluginwrapper and did not work anyway. It must have been several years when I used ICA last time.
