Delete XFCE but keep KDE Plasma – Ubuntu?

Hello, I installed XFCE on Ubuntu. However, it wouldn't start, so I installed KDE Plasma. Now I wanted to uninstall XFCE, but keep KDE Plasma. However, XFCE simply won't uninstall anymore! It can be reset, but it always remains!

How do I get XFCE back down?

Xfce4 is a metapackage, meaning it doesn't have any content of its own, but it does point to dependencies. If all of these dependencies are installed, then Xfce4 is installed.

At least apt cannot do this backwards because apt does not remember what it has installed as a dependency. For this, apt has the command

 apt autoremove

This removes dependencies that are no longer needed. This might help you – as long as you haven't manually installed the Xfce packages individually. Then they'll be marked as manually installed and won't be automatically removed.

But it's interesting that Xfce wouldn't start, but Plasma did. I only know it the other way around…

Then xfwm4 or something similar is still present. Otherwise, it wouldn't be able to boot into it.

But you can simply select Plasma on the login screen, and it should remember that. Although I trust Ubuntu to do anything…

I had this a year ago after a kernel update under openSuSE Leap 15.5

With this kernel I was able to start a KDE session, the one with xfce only showed a green screen

the defective one was: vmlinuz-5.14.21-150500.55.7-default
currently it is: 5.14.21-150500.55.68-default

that works.

Luckily I was still running 15.4.
How can you assume there is a kernel bug when the system runs fine before starting a window manager on a console?
At some point, before installing Leap 15.5, I unplugged the Ethernet cable. It worked!
At some point, I decided to file a bug report at bugzilla_noreply@suse.comSuSE. [Bug 1213438]

4 days later there was a kernel patch for me (only for me?) from Japan
14 days later an official package

I understood from the information shared by many reviewers that this only affected my AMD A10-9700 RADEON R7 CPU.

🤷‍♂️ It doesn't bother anyone. It's just a theme. You can download the themes via the packages

 elementary-icon-theme elementary-icons elementary-xfce-icon-theme

remove.

Das sind nur Designs. Das hat mit Xfce wenig zu tun.
