Welcome back! This is a continuation of my previous blog but before we move further, let's start off with an Attitude of Gratitude! Today, I'm grateful for technology and the way it has kept us all connected with one another. I got to catch up with my brother abroad, whom I haven't seen in person for over 3 years, connect with my relatives over in our hometown, and pray with my boyfriend every night, who lives 2 cities away. I'd love to know, what are you grateful for today? Let me know in the comments!

Alright, back on track...

You probably have read my previous blog post and may be thinking, "what do I do next?!"

When I was watching the video guides on how to set up the Raspberry Pi computer from scratch, I noticed that one had the GUI and the other did not. I wasn't sure if they had set that up or that their GUI loaded automatically after they finished their initial setup in the terminal console but I wanted mine to also have an interface as if I was using my main computer with windows, folders, and files, so here's what I did. Here's what I tried, what worked and what didn't work.

From the Terminal Console

  • log in using the same username and password you used from the initial setup

Troubleshooting opportunity

  • if there are any issues, try using this default

    username: pi / password: raspberry

Tip

Default credentials can be easily found on the Internet in one search. For any default credentials, always make sure to change them into something unique once you successfully log in to prevent anyone from potentially compromising your account.

Some common combinations of requirements for strong passwords are (at least):

  • 1 UPPERCASE
  • 1 lowercase
  • 1 special character/symbol (~, !, @, #, $...)
  • 1 number (0, 1, 2, 3...)
  • avoid consecutive numbers
  • avoid numbers repeating twice in a row
  • avoid commonly used passwords
  • change default passwords
  • use a difficult phrase

Software Configuration Tool page

  • after you've logged in, enter the following command to enter the RasPi Configuration screen

    sudo raspi-config

  • from here, select the first highlighted option using the arrow keys (1 System Options - Configure system settings) IMG_2888.jpg
  • then select S5 Boot / Auto Login - Select boot into desktop or to command line IMG_2889.jpg
  • then B4 Desktop Autologin - Desktop GUI, automatically logged in as '[username]' user IMG_2890.jpg
  • This part popped up so I did what it advised me to do once it sent me back to the Terminal Console

    sudo apt-get install lightdm IMG_2891.jpg

  • after this, type in "yes", then reboot the system by running this command

    sudo reboot

Tip

  • to switch back to the Terminal Console, press Ctrl+Alt+F6 on your keyboard

We did it! (almost)

I was excited to see that we made it to a log-in page of the GUI. Once I logged in using my username and password that I created from the very beginning (see previous blog), the screen went black and brought me back to the same login screen! IMG_2895.jpg At this point, I thought that maybe I was using the wrong login credentials but when I used a different one, it would notify me that the password was incorrect. I tried the same login credentials from earlier and it continued to loop me back to the same page.

Troubleshooting opportunity

  • when in doubt, google!
  • most times, others may have gone through the same issues as you and left documentation somewhere on the Internet -- all we have to do is use it to our expense
  • here is an awesome short blog post that solved my issue

lxsession

  • go back to the Terminal Console (Ctrl+Alt+F4 or F6)
  • run the following command

    sudo apt-get install lxsession What is lxsession: Lightweight X Session Manager -- this is used to initially set up a working environment and applications in the GUI (click the heading to read more about it)

Previous to this, I was running other commands suggested online that did not do much or kept giving me error messages but this one seemed to fix my looping problem.

Now that the login issue is solved, I am able to run my RasPi like an actual desktop!

On to the next projects!
