Newbie Ubuntu user here, currently running 18.04. I haven't had any issues with the kernel until now.

I had to unplug and move my PC out of the room whilst cleaning, and when I plugged everything back in and booted it up, the desktop, login screen and such were all zoomed in, as if I was set to a resolution of 640 x 480. I tried going into the resolutions option menu, but the drop-down has nothing in it. I assumed my video cards needed an update, but every attempt has resulted in a "command not found" output from the terminal. What am I doing wrong? This is what it looks like

Edit: To clarify, all that I have done was the following: I shut down my PC, unplug it following its complete shutdown, plug everything back in and turn it on. It started with the 640 x 480 resolution on its own, with seemingly no user input. I made no changes to the system before this procedure, and in an attempt to fix it, I entered the following command line into the terminal

sudo apt-get-update

Which resulted in an output of

apt-get-update: command not found [like this][2]

  • I can login, no problems there. I simply thought that a visual aid would assist, and the login screen was the first thing I saw.

    Will do, and apologies about the missing information. Still new to all of this.

  • After login, you can open "Display & screen" and try to change resolution. – turbulence Jul 26 '20 at 02:26
  • I gave that a try, but unfortunately the options in the dropdown box were completely missing. – QuantumPizza Jul 26 '20 at 02:27
  • The command not found message is correct, you're not using valid commands (the space is a delimiter and cannot be replaced by a "-") – guiverc Jul 26 '20 at 02:28
  • How would I go about ordering the terminal to update my drivers, then? – QuantumPizza Jul 26 '20 at 02:30

    sudo apt-get-update is not a valid command. You should use sudo apt update followed by sudo apt upgrade to complete system updates. For these two commands, you can also use apt-get instaed of apt, but apt is more user friendly. Please let us know if this helps resolve your issue – Nmath Jul 26 '20 at 03:02
  • It did, thank you. Turns out that there were some drivers that were out of date and needed upgrades, and this solved it. – QuantumPizza Jul 26 '20 at 03:20
