Ubuntu – Taskbar and Tray on Lubuntu gone missing but not on guest account

Seems like setting window type to desktop is not enough sometimes.

Try:

own_window_type desktop
own_window_hints undecorated,below,sticky,skip_taskbar,skip_pager

Got it from here.

Works for me in XFCE. I'm guessing it'll be fine for lxde/openbox as well.

You can remove the Lubuntu splash screen in several ways. If you want to change splash screens every once in a while you can run:

sudo update-alternatives --config default.plymouth

You will be presented with a screen like the following:

In this case, entering a 0 or a 1 will set the splash screen to the Kubuntu logo, while entering 2 will set it to the default Ubuntu logo.

If you want to get rid of the Lubuntu logo permanently, you can remove the package using:

sudo apt-get remove plymouth-theme-lubuntu-logo plymouth-theme-lubuntu-text  

Replacing lubuntu with the desktop environment you installed.

You might be asked to remove lubuntu-desktop that's OK, as its a meta package.

If you've configured gdm using sudo dpkg-reconfigure gdm you shouldn't have a KDE (KDM) login screen. If your login screen looks something like this:

Then try configuring gdm again. If that doesn't work you can remove kdm with:

sudo apt-get remove kdm

Again, you might be asked to remove kubuntu-desktop. Its also a meta package, so go ahead and remove it.
