[SOLVED] Linux Mint 19.2 Cinnamon, how to install & use KDE [SOLVED]

Post by theeo123 » Thu Oct 10, 2019 2:07 pm

As A preface I DID try to search around for this, and my problem is not that I found no solution but I found too many different solutions, many of them very recent.
After trying a few of them I had mixed success. More than once I to use Timeshift to rollback my system as it became unstable.

Code: Select all

 sudo apt install kubuntu-desktop kde-plasma-desktop kscreen
was one of the more frequently mentioned methods

I also see KDE-standard and KDE-Full in the software manager,

another method mentioned adding

Code: Select all

sudo add-apt-repository ppa:kubuntu-ppa/backports
and then

Code: Select all

sudo apt install kubuntu-desktop 
At this point I'm tired of refreshing the system So I thought I'd ask here
what is the best, most stable, way to install and run KDE on my Linux Mint 19.2 Cinnamon system ?

You shouldn't do that. You've created a Frankendesktop. You could start with LM Xfce and go from there, but if it's KDE that you want, install a KDE-based distro. Generally, you shouldn't mix DEs. I use and recommend KDE neon.

That makes me a little sad,
I've grown to Love mint. Especially the great support I've gotten here on the mint forums. but I do like the experiences I've had with KDE. I'm not familiar with Neon as a distro but I'll look into it. Thank you

Mixing DEs can be done, but as you've found out, it often requires a fair amount of work to maintain. There are some distros that will let you install multiple DEs, where the developers have done all the hack work that you've discovered is necessary.

Unfortunately, the Mint devs have seen fit to discontinue producing a KDE spin. The latest and last KDE for LM is 18.3, which is supported until 2021. As for support, the neon forums are quite good.

I use neon :)

Thank you so much for your help, you've been a constant source of knowledge on several of my posts, and I'm learning more each day.
I tried my hand at Manjaro-KDE but has serious problems with both WINE and Samba which were deal breakers. From what I've seen at a quick glance KDE-Neon might be a very good fit.

Thanks again

Not to discourage you from trying KDE Neon, but you also should consider Kubuntu. Or maybe try that next if KDE Neon doesn't work for you.

To be clear, I've not used either one as my main Linux system. I only have them installed in test boxes for comparison.

Ok Tried Neon had some issues with it trying to install the wrong Video card drivers, tried Kubuntu, tried Manjaro


Getting frustrated, Samba/file-sharing on KDE seems to be a real mess,
Wine's support, and EASY file sharing are deal breakers for me. I like the KDE look feel, the effects, the wobbly windows, and all that cheesy stupid little stuff but it's not worth having a system that won't function So I may be back on Linux Mint very soon

Each of those distributions has a forum, you know.
You can pursue issues with them before throwing in the towel.
Or not, if you've already invested as much time as it's worth to you.

Manjaro treated me rather unkindly when I tried their forum, which is a shame because overall it seems like a great distro. I tried for about a week to get file sharing working the way I want, and have had no success.

In Mint it just works out of the box with no problems for me

There is an article in the tutorials forum (at least that's where I think it is) by forum admin xenopeek that shows how to install KDE over the top of xfce. I'll see if I can find it... a few seconds later... viewtopic.php?t=267121

You should read and understand the entire thread before you try it.

Thank you So Much!!

I might try it, but I am trying to take to hear what you said about creating a frankendesktop, i may just stick to Cinnamon for now, and make sure everything is working and stable first

If you follow advice at the first link then that at the end of the second link to uninstall xfce, it should work quite satisfactorily. Perhaps you could try it in a virtual machine.

No worries. Just don't install virtualbox from the software manager or ubuntu repositories. Let me know if you need help installing it and I'll post the instructions for you.

No worries, worked with Vbox a lot before making the switch to Linux, I'm more or less familiar with it. But again thank you for being such a big help.

You haven't really said why KDE will not install. From what you wrote you were on the right path to getting it installed. Use kubuntu backport then install kubutntu-desktop, etc.

I just upgraded a system to mint 19.2 and then installed KDE on it successfully. The second one I have done.

There is an issue though. An old version of a package creates a conflict because it is no longer maintained by Mint and KDE needs it installed.

The package software-properties-kde (0.96.x) in Linux Mint 19.x creates a conflict with mintsources (1.8.x).

The way to resolve this properly is to install software-properties-kde (1.8.0 or greater). This can be obtained from UbuntUpdates.org: Download 1.8.0 package for Tara here (Tessa version 1.8.4 also available): https://www.ubuntuupdates.org/package/m ... erties-kde

The 1.8.x version contains almost nothing and depends only on mintsources being installed. Thereby eliminating the conflict for Mint and allowing kubuntu-desktop and other software to install correctly.

I have fixed a system that had this exact problem, where I forced the old 0.96.x version in only to have an issue with mintupdate constantly wanting to install mintsources 1.8.8 (in Tina) and remove kubuntu-desktop! Installing software-properties-kde 1.8.0 with dpkg gave no errors, then trying mintupdate again it installed mintsources without conflict or asking to remove kubuntu-desktop.

Good luck.
