I'm trying to learn how to use Ubuntu, but I must say I didn't have half as many issues with 16 as I have had with 18.04

I'm using a laptop and I'm at a beginner-level. (But I'm willing to learn) And basically I'm having a lot of lag, and perhaps I don't have the correct drivers.

I'd need an easy command to pull up my system info, and then run a check on my drivers and download what's needed.

Proc: AMD e1-1200 APU with Radeon HD graphics x2, Mem: 3.5m total, 1.7g used, 651m free, Swap: 3.6g total, 29m used, 3.6g free

CPU MHz: 778.147, CPU max MHz: 1400.0000, CPU min MHz: 777.0000

This has been answered before but in two parts.

First displaying loaded kernel modules.

Linux (and Ubuntu as well) doesn't have separate entity as "device drivers", Linux has kernel modules which could be called "drivers" for real or virtual hardware depending on their functionality.

Use lsmod or cat /proc/modules to see list of loaded kernel modules. Also you can see list of all available (installed) kernel modules in system using:

ls -R /lib/modules/`uname -r`/kernel/

Source | find list of installed device drivers ubuntu

Next, using Software Sources > Additional Drivers, for installing device drivers, often proprietary.

Unity (15.10 and 15.04/14.04/13.04/14.10/13.10/12.10)

Click on the gear icon on the top right corner of your screen and click on "System Settings" from that menu, click on Software Sources (or you can click on the Ubuntu button and search for "Sources":

and then on the Additional drivers tab:

In 20.04, go to the application launcher and launch "Additional Drivers" here you can find available drivers for your hardware as well as see the ones you are using Whereas in 18.04, you need to go to Software And Updates to : additional drivers and select the fifth option which is : Additional Drivers

You may just not have enough horsepower to make Ubuntu speedy. Or you may have not installed the Radeon-specific video drivers. One solution is to use a version of Ubuntu that takes less resources, like Xubuntu. However, lets try these two things first...

Attempt #1:

Disable wayland, if it's running...

In terminal...

sudo pico /etc/gdm3/custom.conf # edit this file

change:

#WaylandEnable=false

to:

WaylandEnable=false

then reboot.

Attempt #2:

Use the lightdm display manager...

In terminal...

sudo dpkg-reconfigure lightdm # select lightdm and click OK

use

sudo dpkg-reconfigure gdm3 (ignore any error messages about gdm3 not running)

if you wish to set it back to gdm3 display manager.

then reboot.

Attempt #3:

Download the xubuntu .iso and burn it to a DVD or flash USB key. Boot to it, and see if things operate better for you. If they do, you may wish to switch from Ubuntu to Xubuntu.
