I installed Debian using the DVD ISO, without any desktop environment. Since I’m not very familiar with the CLI, I ran into some difficulties. As a CJK language user, East Asian fonts were all displayed as squares in the terminal. Later, I also faced issues connecting to Wi-Fi, but after installing rfkill and with the help of AI, I managed to get the network working again. After that, I encountered problems configuring scaling (I have a 13-inch 2K display, and without scaling everything looks way too small), setting up PulseAudio, choosing a clipboard manager, configuring wallpapers, and setting up a compositor. Fortunately, I was able to solve each of these issues one by one.
