Unable to install KDE Plasma Desktop Environment from Manjaro Gnome

Support KDE Plasma

I wanted to install KDE Plasma alongside with GNOME, so I followed the instructions on the wiki: https://wiki.manjaro.org/index.php/Install_Desktop_Environments#KDE_Plasma_5 but I faced this issue

What I am missing?

Thanks in advance

You can’t install both – you need to chose one. Better option for install KDE is plasma-meta package. And also it’s not recommended mixing different DE in one installation.

Replacing plasma to plasma-meta seems to work. Thanks.

 ~ sudo pacman -S plasma-meta kio-extras

I am aware, but thanks for the warning :slightly_smiling_face:.

So now make sure you have proper services enabled/disabled when you use different DE.

What do you mean?

Optional: Install and use SDDM, the recommended display manager for KDE

SDDM is installed as a dependency of plasma. To enable it

systemctl enable sddm.service --force systemctl reboot

This for example?

I don’t have a list and that’s what you should research for upcoming issues you will surely have mixing two different desktop environments.

The Risks of Using Multiple DEs

Installing multiple DEs is not without risks. Here are some things that can pop-up when running more than one DE:

  • The settings packages overlap so you can only have one DE pre-configured with the Manjaro theming. The others will need to have the theming applied manually.
  • You can end up with more than one instance of similar applications. For example, it is common to end up with 2 Bluetooth managers. It takes some tweaking to get a single manager working in multiple DEs
  • Sometimes two different DEs will share the same configuration files causing strange things to happen, especially with theming

These risks are greatly reduced by using a different user account for each DE.

In summary, running multiple DEs is possible and a great way to enjoy Manjaro but it requires a willingness to troubleshoot and work through minor problems. If you are the type of person who wants everything to “just work” out of the box, running multiple DEs might not be for you.

hi, is this meta packages full of latest KDE plasma feature?

10

If I understand correctly, plasma-meta and plasma should provide the same functionality, with the difference that plasma is a group of packages while plasma-meta is a meta package.
