Raspberry Pi & iPad thru VNC Server

Hi. I really enjoy musescore easy to use and clean printing.

To minimize my carrying stuffs, I’m trying switching to raspberry pi (RPi) from laptop.

I could install musescore onto RPi, and it seems working okay so far.

Due to tiny 3.5” screen on RPi, I’m trying connect to iPad (as a monitor with touch pad) thru VNC Server.

It boots on iPad, however, Bluetooth keyboard doesn’t work correctly, layout is messed up (ig, “a” key inputs “g”, “s” key inputs “b”).

This problem is only on musescore.

Bluetooth works good on iPad, also terminal on iPad from RPi thru VNC.

I have no idea where is wrong, if anyone can help me...?
