Shutter screenshot tool in Ubuntu 20.04

I frequently use screen capture to record the steps in using software. The best tool for doing this is Shutter. So I make it available every time my Ubuntu 20.04 starts.

Step 1: Open Startup Applications

---

From the left corner button, click Show Applications

 

then select Startup Applications

---

Step 2: Add shutter in startup list

Shutter should be listed in the startup program by adding the command. 

For the name field, type: shutter

For the command field, type: shutter --min_at_startup

the click Save button.

Step 3: Restart Ubuntu

---

To make Shutter runs on startup, then restart the machine and you can see the shutter icon. Shutter is now ready to use.

and enjoy using Shutter.

Minbar Prayer Times in Ubuntu 14.04

I recently installed Ubuntu 14.04 replacing the old version 11.04 (not upgrading), then I did the following steps to install Minbar Prayer

a) Install Minbar Prayer Times from Ubuntu Software Center
b) Include minbar in startup program

c) Set the preference of minbar to "startup minimised to tray"

In older Ubuntu versions Minbar Prayer Times should be located on right top panel, but now it is missing. Rebooting the machine did not help.

Then I did the following steps to show the Minbar icon:
Step 1: From Ubuntu terminal (Ctrl+Alt+T), enter the command
sudo apt-add-repository ppa:gurqn/systray-trusty

Step 2: enter the command
sudo apt-get update

Step 3: enter the command
sudo apt-get upgrade

Step 4: then reboot the system by entering the command
sudo reboot

Finally the icon Minbar Prayer Time shown on top panel, and it starts (but minimised mode) every time the system starts.
