Ubuntu – Kubuntu 16.04.1 boots slowly


I have been using Kubuntu 16.04.1 for almost a month, so far so good, but the boot is very slow, I was using Ubuntu Gnome before it and it booted in 5 seconds, Kubuntu takes a minute and a half just loading the Kubuntu logo, And nothing else is installed alongside Kubuntu.

Any idea how to fix this? I have an SSD by the way.

Best Answer

Well, Kubuntu is the slowest ubuntu-based distro.

If you want to make it faster, try to:

  • install e4rat (not recommended if you use an SSD);
  • Disable useless services. I may suggest you to disable network manager, the splash screen (How to disable Plymouth), wpa_supplicant, your display manager (KDM) - just use TTY;
  • Remove bloatware packages (packages you never use but are preinstalled)

... or just install Xubuntu / Lubuntu.
