Recent purchase of KVM-A3 device, set it all up with a downloaded OS. Everything seems to be working ok, and I can view and control a PC connected to KVM-A3, the only issue us that the 0.96" OLED display is dead, never lighting up. Any idea why this might be?
Display is inserted correctly into connector and screwed into place.
Found some information and got it working:
Set file system to read/write with
rw
Added this to /boot/config.txt:
dtparam=i2c_arm=on
Then did this:
echo i2c-dev | sudo tee /etc/modules-load.d/i2c-dev.conf
Then enabled kvmd-oled with this:
systemctl enable --now kvmd-oled
Then set file system back to read only, and rebooted:
ro
reboot
OLED now working.
If the KVM-A3 itself is working fine but the OLED never powers on, it could be a firmware/config issue rather than a bad connection. A couple things to try:
Make sure you’re on the latest firmware for the KVM-A3 (some earlier builds had display bugs).
Double-check the ribbon orientation in the socket – even if it feels seated, flipping/reseating can help.
If it still doesn’t light up at all, the OLED panel itself may be defective and you might need a replacement.
