I installed the
xfce-desktop package in order to give myself a lighter GUI to improve the performance of Kerbal Space Program -- and KSP now works great! However, since first logging into the XFCE Session or Xubuntu session, every time my screen locks (manual or timed) while logged into KDE Plasma I get an XFCE login, followed by a KDE login to unlock the screen. I'm also seeing the XFCE login screen when fresh starting the system, and I'd much rather have the KDE Plasma login.
If it matters, I'm on a Core2Duo, 8 GB RAM, nVidia GTx950 w/ 1 GB. Everything was working fine before installed XFCE, except (I was told) the load from KDE Plasma was affecting my game's performance.
$ sudo dpkg-reconfigure kdm dpkg-query: package 'kdm' is not installed and no information is available Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents. /usr/sbin/dpkg-reconfigure: kdm is not installed
I'm pretty sure I've had
lightdm from installation of 14.04, rather than
kdm -- and
lightdm is still present (shows in task list).
How can I correct this?
