Uninstalling Unity and Replacing it with Kubuntu-desktop the right way?

[Goddard]

I installed Ubuntu using the alternative installer because none of the graphical installers support software raid configurations at least that well. I then installed ubuntu-desktop, but have since install kubuntu-desktop because I like it better. I noticed something that made me thing possibly Unity is running in the background in some fashion because when rebooting, or shutting down I see a flash of my old Unity desktop, meaning the wallpaper changes to what I previously had on Unity.

First is this a bug?

Second how can I remove this issue? Should I replace LightDM? What is a nice KDE way of doing this? Thanks.

Sounds like you haven't removed Unity and its dependancies. Try this

sudo apt-get remove ubuntu-desktop

[Goddard]

Thanks NickStone I have already removed unity, ubuntu-desktop and a few other packages, but the problem still exists. I was going to remove LightDM as I thought it might be related, but wanted to ask you all first. Maybe I can get a video showing what I mean.

You might go through the list and remove as many of those as you can without removing kubuntu-desktop.

Just as a comment, I've installed KDE over "Ubuntu" and then "Ubuntu Unity", and also...."on" Debian... and I've said this before, but was laughed at..."KDE" is there, but it just doesn't "seem the same"...it works...... but... the best word I can come up with is "hard/brittle(not breaking, but..."hard" in "feel/texture, whatever, a....."rendering thing'...

But, it does work if one just "lets synaptic do it".

Installing the unity-desktop (or kubuntu-desktop for that matter) meta-package pulls in vastly more packages than ypu might think. the *-desktop package in and of itself has no software in it whatsoever, and simply depends on everything that makes up the base desktop for that particular flavour. Removing unity-desktop will NOT remove any of the unity components, just like removing kubuntu-desktop will not remove any of KDE.

Now this flash of the other desktop probably is a bug of sorts, one I remember from many many years ago, and I do not think is related specifically to one login manager, or distro (I used to see this when I had multiple desktops installed, well before lightdm) ever existed.). I am not positive, but I think it might be some cache or the like, and always was the Gnome desktop that would show itself during login/logout.

I do not think that Unity is actually running, you would probably see that in a task manager.

**UPDATE** from a super duper quick web search, it could be nautilus running in the background, or possibly some buffer in the gpu.
You can try switching to lightdm-kde-greeter or KDM to see if that helps.

Yep looks like it was Nautilus. Nautilus for what ever reason was started and that also runs the "desktop" apparently for unity. After I removed Nautilus the problem went away.
