KWin is installed by default, but to run it needs a dependency, xwayland, which is NOT installed. There is probably a reason why it wasn't installed by default.

If you have your GPU running without problems then the old advice still applies: if it ain't broke then don't fix it.

Hello thanks for your answer , I see one I have the choice between "SSDM" and "lightdm" during install ... aie , I have choice "lightdm" big error ...many thanks I return

[GreyGeek]

Na, your fine. Just install
sddm
kde-config-sddm
sddm-theme-breeze
(and any other sddm themes you want).

Then
systemctl enable sddm
systemctl disable lightdm
(uninstalling lightdm will remove it)

Then reboot.
If you boot into a console then you may have to issue
systemctl start sddm

kwin on

@ greygeek,
Dac-o-dac , but I have many OSs not exclusive kubuntu.... usually I use plasma 4 , but with the new plasma5, it's a big problem for me .... KDE /kubuntu decide to change any "advantage" virtual office" 1 or 6 always the same picture on anyone not possible to change any one for an other..... and the best for me screensaver with the choice the "clock"... disappear and they other also .... It's not critical .... just a reflection..... I have install the last Xubuntu 16.04 just plasma 5.... What do you think about it ? I try it on my xubuntu 16.04 with success and the right to do thank you see you soon

[GreyGeek]

If you don't want plasma 5 then stay with 14.04. Its End Of Life is 4/2019. There is no practical way to remove systemd or revert to plasma 4

Many thanks, I try to renew the plasma 4 on xubuntu or kubuntu 14.04 .... I think it's not possible , I'm happy to testing that

[GreyGeek]

14.04 is a GREAT release, and very stable by now. It does not have systemd. Upstart is still in control, which means you'll be using "sudo <someservice> start"
where the services are listed in the /etc/init.d subdirectory.
Best to reinstall it from the latest point release freshly downloaded, sum checked, and burned to a USB stick or a DVD.

[jibel]

Okey thank you, I do that for my next test on kubuntu 14.04
