Make App Window Transparent in Ubuntu 18.04, 18.10


This quick tutorial is going to show you how to make any application window in Ubuntu Gnome transparent.

Since Ubuntu 18.04 switched to Gnome 3 desktop, you can no longer set transparent application window with CCSM utility.


As a workaround, you can run following steps to set any application window opacity in Ubuntu 18.04, and Ubuntu 18.10.

1. Open terminal either via Ctrl+Alt+T or from software launcher.


2. When terminal opens, paste following the command and hit enter:

sh -c 'xprop -f _NET_WM_WINDOW_OPACITY 32c -set _NET_WM_WINDOW_OPACITY $(printf 0x%x $((0xffffffff * 80 / 100)))'

Your mouse cursor will become cross-shaped, simply click on any window and it become 80% opacity.


In the command, you can change 80 to number range from 1 ~ 99 for other window opacity.

3. To reset the window opacity, run command:

sh -c 'xprop -f _NET_WM_WINDOW_OPACITY 32c -set _NET_WM_WINDOW_OPACITY $(printf 0x%x $((0xffffffff * 100 / 100)))'

When mouse cursor changes, click on the window to reset its transparent level.
