[Solved] Raspberry Pi 5 - Display Resolution and Orientation stuck

[Krishnakanth Alagiri]

The Issue I had

The resolution and orientation was stuck to 1920x1080 and portrait when I tried to install MPI4008-show

Simple fix

• Raspberry Pi OS appears to be bundled with the ads7846 kernel module.
• Most of the scripts are configuring the OS to work with the screen than installing new drivers/modules.
• Just install sudo apt-get install xserver-xorg-input-evdev
• Add the below to your /boot/config.txt

dtparam=i2c_arm=on
enable_uart=1
dtparam=spi=on
dtoverlay=ads7846,cs=1,penirq=25,penirq_pull=2,speed=50000,keep_vref_on=0,swapxy=0,pmax=255,xohms=150,xmin=200,xmax=3900,ymin=200,ymax=3900

• (Optional) You can change the resolution via Start Menu > Preference > Screen Configuration or Screen Layout Editor. If you're working without a desktop environment, modify the hdmi_mode and hdmi_group on /boot/config.txt. 480x800 works best for me.
• (Optional) If your Pi is confused with touch coordinates after modifying the orientation, you might need flip swapxy to 1.
• (Optionally) Calibrate your touch screen.
• Have fun!
