Unable to change Docky configuration in Lubuntu 18.04

This maybe a stupid question, with easy fix. But I searching around to no avail.

I'm unable to change docky configuration, I tried opening the docky setting on the dock, but the option to make it hide was grayed out.

How would I modify the option ? Or is the Docky project really dead, before Docky I'm using Plank but it doesn't have animation. If Plank has animation, I would stay with that.

FYI: I install it with sudo apt install docky

Solution 1:

To make Plank show animation on hover with Compton as the compositor

Open a terminal and run plank --preferences

You'll get a window looking like this:

You can adjust the value of Icon zoom to suit your needs.

Compositing

• Lubuntu 18.04 comes with its own compositor called Compton which you can start from Menu > Accessories > compton.
• There's also a very nice interface for adjusting Compton's settings. This GUI is called Window Effects and is found under Menu > Preferences > Window Effects.
• Once you start Compton make the changes you want in Window Effects, go to Menu > Preferences > Default applications for LXSession and in the window that opens, add Compton to your Autostart as in the image below.

Solution 2:

After searching around, it turns out Docky require compositing in order to work properly, and compositing reside in Compiz window manager.

So I tried to find the workaround, and found the fix:

sudo apt install xcompmgr

or

sudo apt install compton ###I USE THIS

Both will apply compositing, which enable Docky full capabilities.

However, there are price to pay. The compositing made Lubuntu desktop buggy, for example:

• Desktop background only shows gray color.
• Screen tearing
• etc.

I guess Im gonna stick with Plank, the dock that works stable on Lubuntu without further hack.
