I successfuly installed Kubuntu 20.10 on my tablet but did not managed to setup touchscreen. I always get this dmesg output: [ 8.265859] chipone_icn8505 i2c-CHPN0001:00: Warning ACPI _SUB failed: 0x5 [ 8.267159] chipone_icn8505 i2c-CHPN0001:00: Direct firmware load for chipone/icn8505-unknown.fw failed with error -2 [ 8.267166] chipone_icn8505 i2c-CHPN0001:00: Firmware request error -2 [ 8.267341] chipone_icn8505: probe of i2c-CHPN0001:00 failed with error -2 When I tried to rename firmware file to icn8505-unknown.fw only first line remained but it's still not working.

I also tried to compile chipone driver but I always get this error (It's partly in Czech but it's understandable):
