Debian 12 - KDE Setup Desktop Script

I'm upgrading from Xubutu 20/22 to Debian 12 with KDE because I really don't like what Canonical are doing, especially with regards to shoving snaps down our throats, and I really like the KDE desktop. So far everything has pretty much "just worked" and I love how easy it is to configure the KDE desktop exactly how you want it.

Disable Trackpad Middle Mouse Pasting

I have a buttonless trackpad, and I was having all sorts of issues until I realized that I was occasionally pressing the "middle" mouse button and pasting text instead of left/right clicking. One can easily disable this.

Sublime Theme

After having done this, one may wish to refer to installing the Flatland Sublime theme.

Screenshotting

Coming from Xubuntu 22.04 where I am used to using Shutter and Ksnip, neither of these tools would work for me. I think this is because of Wayland. In the end, one can configure KDE's spectacle application how one wishes, or one can simply install and use Flameshot, which is also pretty good and I added to my script.

Modern Firefox

Debian 12 comes with Firefox ESR (extended support release) by default. To upgraded to the latest firefox, follow my tutorial: Install Firefox From APT Repository
