Although I'm not a friend of Ubuntoids (since Debian exists) I decided to try it new edition Ubuntu 19.10 Eoan Ermine.
Installing the new operating system won't be difficult for you, since it hasn't changed anything in the installer that Canonical has been using for years. Canonical's operating system comes in many flavors (different desktop environments). I first chose the Ubuntu 19.10 Eoan Ermine ISO that uses it Gnome DE, knowing that I would have to change it to KDE Plasma later, because Gnome's desktop scaling never pleased me.
The Gnome DE comes with x1 and x2 display options, which doesn't help with 1920 × 1080 HD screens. On the contrary, KDE Plasma's HiDPI system is much more manageable with more options as it offers scaling of 1.1, 1.2, 1.3, 1.4 etc.
Choosing the standard ISO rather than Kubuntu was because I wanted to see the default tools of Gnome.
But before we go into the description of the KDE installation, let's take a look at the picture above.
The new version supports (experimental) the ZFS file system. Yes it's still in the experimental phase, but you can choose to use ZFS instead of the default EXT4 file system when installing Ubuntu 19.10.
Another very important thing is to add NVIDIA's proprietary drivers to the ISO standard. This means that you can now install your own NVIDIA graphics driver while installing Ubuntu 19.10 even when you are offline.
NVIDIA drivers are about 115 MB in size and this increases the size of ISO. Flavors like Ubuntu MATE have removed less commonly used programs like language packs to maintain the ISO size of around 2 GB. Of course, you can download these packages after you install your operating system.
After a first glance, I decided to install KDE Plasma, since trying to increase the font size didn't have the expected effect of scaling important applications such as the Firefox browser.
To install Kubuntu DE:
Open the Terminal application via Dash or Ctrl + Alt + T shortcut.
We will first install Tasksel, a basic application for installing Kubuntu.
The system will ask you to provide the password for your sudo account. Enter the password to start the installation process. During installation, the system will prompt you with a Y / n option to confirm the installation. Type y and press Enter to finish the software installation.
Now that you have tasksel installed on your system, type the following command to install the Kubuntu desktop:
The two images below will appear. Simply press Enter on the first one, and in the second, select the display manager you want.
I chose the KDE DM (SDDM) because it's my closest.
In some systems, this second option is not presented alone. For these systems, you will need to manually install sddm using the following command:
After setting up sddm, you will need to restart your system. After login you will have a base, with all Gnome applications, but with the KDE HiDPI configuration capabilities.
