We are creating a series of YouTube videos under the “edu-“ label to guide users through the migration from ArcoLinux to Arch Linux. These tutorials aim to make the transition process smoother by explaining each step clearly and providing practical examples. Whether you’re switching to gain more control or to learn vanilla Arch, our edu- videos are here to support your journey.

ArcoLinux has stopped

Teaching never stops—because learning is a lifelong journey for all of us.

44 How to change the icons in Plasma

short video

The short video can be summarized in one simple sentence.

IF qt5ct is installed, change your icons in the QT5 Configuration Tool.

Take a look at the top image.

Long and technical version

In the long video we will show you the code inside the configuration files and reboot many times in order to see and understand where the settings are coming from and why things seem not work.

You will see why icon themes ARE NOT APPLIED even when you told Plasma to apply it.

QT5CT is installed

the settings from ~/config/qt5ct/qt5ct.conf are applied.
Change the settings via qt5ct and apply.

Qt5ct overrules the settings of plasma.

QT5CT is removed or not installed

the settings come from ~/.config/kdeglobals
Change your icons in system settings now.

Over time we will evaluate the best approach for plasma.

To qt5ct or not to qt5ct, that is the question.

TIP : Reboot your system so that the icons are applied

SKEL will copy/paste the original settings back
