Change file association in KDE Plasma (5.24) – open PNG with different default application

Changing the default file association in modern KDE Plasma Desktop under any Linux Distribution is pretty easy. Here are couple of screenshots how easy is to change the default file association to open a PNG file with different application. Sometimes the default application to open a file may not be convenient for the user or just the Linux Distribution did not change it when installing a new application.
For example, in the sample workstation, the PNG file is meant to be open with the KDE KolourPaint, which is good for simple image manipulation, but not to view multiple images in a series.

SCREENSHOT 1) Launch KDE Plasma System Settings

KDE Plasma windows force resize – iKVM virtual keyboard

If you happen to use KDE Plasma these days and you encounter view problems like you cannot see the whole viewpoint of a window (especially JAVA/GTK based programs?).

KDE Plasma Desktop offers the ability to force a window to expand to new dimensions.

STEP 1) The Java-based iKVM program window has a handful virtual keyboard.

It could be used to “click on” specific key combinations, which otherwise could be caught by your system. But in sometimes the virtual keyboad window is trimmed and you lose some important keys like Ctrl, Alt, Space, arrow keys and more (the last line of buttons).

Review of freshly installed Fedora 31 KDE Plasma Desktop (KDE GUI)

After the tutorial of Install Fedora 31 KDE Plasma Desktop this tutorial is mainly to see what to expect from a freshly installed Fedora 31 KDE Plasma Desktop – the look and feel of the new KDE GUI (version 5.13.5 of KDE Plasma).
Here you can find how to Install Fedora 31 KDE Plasma Desktop (KDE GUI). Here it worth mentioning the included versions of KDE software for Fedora 31:
The Fedora 29 KDE Plasma Desktop comes with

KDE Plasma version: 5.16.5
KDE Frameworks version: 5.61.0
QT version: 5.12.5

The idea of this tutorial is just to see what to expect from Fedora 31 KDE Plasma – the look and feel of the GUI, the default installed programs and their look and how to do some basic steps with them, it is included also screenshots of the KDE settings program. Here you’ll find more than 200 screenshots and not so many texts we do not want to turn this review of many texts and version information and 3 meaningless screenshots, which you could not see anything for the user interface because these days it is the primary goal of a Desktop system. You can expect more of this kind of review in the future.
It may be interesting to compare with the Fedora 29 review – Review of freshly installed Fedora 29 KDE Plasma Desktop (KDE GUI)

Install Fedora 31 KDE Plasma Desktop (KDE GUI)

This tutorial will show you the simple steps of installing a modern Linux Distribution Fedora 31 KDE Plasma Desktop with KDE for the user graphical interface. First, we present the basic steps for installing the Operating system in addition to your present operating systems (here we have two: Windows 10) and then you can see some screenshots of the installed system and the look and feel of it. We have another tutorial showing more screenshots of the installed and working Fedora 31 (Gnome and KDE plasma) – so you can decide which of them to try first – coming soon.

The Fedora 31 KDE Plasma Desktop comes with

Xorg X server – 1.20.5 XWayland is used by default
linux kernel – 5.3.7
KDE Plasma version: 5.16.5
KDE Frameworks version: 5.61.0
QT version: 5.12.5

The installation process is very similar to the old Install Fedora 27 KDE Plasma Desktop and Install Fedora 29 KDE Plasma Desktop (KDE GUI). Our system is relatively new – Asus X399 with AMD Ryzen Threadripper 1950X and NVIDIA 1080 TI and the setup loaded successfully and there were no problems till the end.

We used the following ISO for the installation process:

https://download.fedoraproject.org/pub/fedora/linux/releases/31/Spins/x86_64/iso/Fedora-KDE-Live-x86_64-31-1.9.iso

It is a LIVE image so you can try it before installing it. The easiest way is just to download the image and burn it to a DVD disk and then follow the installation below:

SCREENSHOT 1) Here is our “UEFI BIOS->Boot->Boot Override” and in most modern motherboard you can choose to override the default boot devices.

Choose the “UEFI: HL-DT-STDVDRAM…” to boot and install Fedora KDE Plasma Desktop 31 with UEFI support. You should do this, because most of the new hardware like video cards would not work properly without beeing in UEFI mode.

Gentoo kde-frameworks/kdewebkit failed compilation with Qt5WebKit could not be found because dependency is required

Updating the KDE Plasma Desktop in our Gentoo workstations this time failed with

CMake Error at /usr/share/cmake/Modules/CMakeFindDependencyMacro.cmake:48 (find_package):
  Found package configuration file:

    /usr/lib64/cmake/Qt5WebKit/Qt5WebKitConfig.cmake

  but it set Qt5WebKit_FOUND to FALSE so package "Qt5WebKit" is considered to
  be NOT FOUND.  Reason given by package:

  Qt5WebKit could not be found because dependency is required to have exact
  version 5.11.x.

It was strange because the previous emerge included the QT upgrade from old 5.11.2 to 5.12.1 and this dependency should have been resolved properly before:

emerge -vau $(qlist -IC|grep dev-qt|sort|uniq)

But apparently despite that the emerge built all QT libraries in dependency order the “dev-qt/qtwebkit” was built against the old QT libraries. And this is what is saying the above error!

The solution is really simple just rebuild the dev-qt/qtwebkit

root@srv ~ # emerge -va dev-qt/qtwebkit

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] dev-qt/qtwebkit-5.212.0_pre20180120:5/5.212::gentoo  USE="X geolocation hyphen jit multimedia opengl printsupport qml -gles2 -gstreamer -nsplugin 
-orientation -webp" 0 KiB

Total: 1 package (1 reinstall), Size of downloads: 0 KiB

Would you like to merge these packages? [Yes/No] yes
