Speed Up ‘Alt-Tab’ Task Switcher Popup in Ubuntu 18.04

Last updated: August 23, 2019

Feel that Gnome desktop ‘Alt+Tab’ popup is slow? There’s by default 0.15 second popup delay when you pressing Alt+Tab on keyboard.

It’s nothing serious for some people including me. But if you want to remove the delay to speed up task switcher popup, it can be done easily via gnome shell extension.

Open Ubuntu Software, search for remove alt tab popup and install the extension.

It takes effect immediately after you installed the extension. And as noted it effects all kinds of pop-ups.

To manage the Gnome Shell extension, install and open Gnome Tweaks, then go to Extensions tab.

How to Enable On Screen Keyboard in Ubuntu 18.04

Last updated: July 22, 2019

In Ubuntu 18.04 and higher, Gnome’s built-in screen keyboard can be enabled via universal access menu.

However, it only triggers automatically in Gnome Activities and Application menu, nowhere else. See the bug. Though it’s marked as fixed, I still have the problem in my laptop.

For those have the same issue, you can install the previous Ubuntu 16.04’s default onboard screen keyboard utility in Ubuntu 18.04 as a workaround.

Open Ubuntu Software, search for and install onboard as well as onboard settings.

Once installed, launch the utility from Gnome application menu.

In onboard settings, set up auto-show, layout, theme, etc and enjoy!
