[KDE] When 'exit' doesn't kill the application

[johnzbesko]

Here's a weird bug. When I close konqueror either with File-Exit or clicking the X in the top right of the window, the window closes, but the job/process is still running, as shown by 'ps -ef/grep konq'. I am unable to reopen konqueror, unless I 'kill -9 00000' the job. Using xKill on the window does kill konqueror and I am able to restart from the start menu. Also, the video previews do not show up even though I have kffmpegthumbnailer installed. These problems arose with my upgrade from 16.04 to 18.04.

Konqueror

Bug 388333 - How to create new konqueror processes? : https://bugs.kde.org/show_bug.cgi?id=388333
KDE forums: problem using konqueror - https://forum.kde.org/viewtopic.php?f=309&t=142697

The Konqueror is not terminating from the window decorating close button or from the Konqueror Quit button. This prevents the start of a new Konqueror window.

A workaround: Konqueror settings > Performance > Disable the 'Always try to have one preloaded instance'.
Note ! You will need to kill (system activity) existing Konqueror session before this takes effect.

KDE video thumbnailer plugins

The Konqueror,

$ konqueror -v
konqueror 5.0.97

is a KDE Frameworks 5 (KF5) application. It can use KF5 / Qt 5 plugins.

kffmpegthumbnailer - https://packages.ubuntu.com/search?k...pegthumbnailer

An old videothumbnailer for the KDE4, using Qt4.

ffmpegthumbs - https://packages.ubuntu.com/search?k...ll&section=all

Official KDE videothumbnailer for the KF5, using Qt5.

Preview plugin settings

Konnqueror settings > File Management > General > Previews

Thanks, the "pre-loaded instance" workaround worked. Another puzzle- when I attempt to "Configure - Konqueror" only two menu choices are visible, Performance and Bookmarks. All the others (that I have seen in the past) are missing. I had both the kffmegthumbnailer and the plain ffmegthumbnailer packages installed and then I removed the plain one and reinstalled the k one. No help. Where did my "Configure - Konqueror" go to

BTW, I upgraded (not fresh install) from 16.04 to 18.04.

Missing modules ?

If there are 'Unable to load "****" configuration module' when starting the Konqueror from the terminal window.



If the suggested package: https://packages.ubuntu.com/bionic/konqueror is not installed.



Is the Package: konq-plugins: https://packages.ubuntu.com/bionic/konq-plugins installed ?



kffmegthumbnailer

The kffmegthumbnailer won't work with the KDE Frameworks 5 !

[johnzbesko]

OK, all your suggestions/instructions (konq-plugins, ffmpegthumbs, not kffmpegthumbs) worked for me. Thank you!

I have weird problems with vlc, but that's for a different forum.
