If the Raspberry Pi isn't detecting the screen size correctly, you might need to tweak video mode settings and maybe tell the Pi to ignore the capabilities reported by the display. For example, some of the Chalkboard Electronics screens require installing an EDID file and/or changing the boot configuration.
If you run into problems with input events being dropped, you should try reducing the USB bus speed. You need recent firmware to do this, so first you should update firmware:
| Code Block | ||||
|---|---|---|---|---|
| ||||
sudo apt-get update
sudo apt-get install raspberrypi-bootloader --reinstall |
Then open /boot/cmdline.txt in an editor and add on the same line as the other options dwc_otg.speed=1. Run sudo sync and reboot. This drops USB speeds from 480Mbits/s to 12Mbits/s, which is known to resolve issues with a variety of USB devices on the Raspberry Pi.
