I have a Waveshare 3.2 inch touchscreen that I am using with a Raspberry Pi 3 and Raspbian OS. The screen works fine and I can toggle to a HDMI monitor and back with no problem. The problem I am having is that nothing fits on the 3.2inch display. Any window I open is too big and gets cut off on the right and bottom of the screen. What settings do I need to change in the /boot/config.txt file in order to make the windows stay within the 320x240 bounds of the touchscreen? Any and all input is appreciated.
I just found out a solution, if you're running a raspbian stretch (not lite) distro, you can simply go back to the terminal mode (cli mode) and enter the following command :
sudo apt-get --purge remove lightdm
This will remove the DE in which raspbian boots into, and then it will install the standard LXDE desktop environment, in which almost all the applications (not all, some of them still go out of the screen) will run within the screen itself, Good Luck! Trust me, it worked
Edit : The Default DE for raspbian stretch is PIXEL
