There is no writren record nor recordings (of course) of such ancient music. Yes, there are some hints like greek musical modes but they are not trustable in terms of historicity. You could guess greek folk music has a relationship with this ancient music and speculate a little based on archaelogical evidence of instruments, but: nobody knows how roman or greek ancient music sounded.
To enable gesture typing, download Google's gesture typing library at https://github.com/erkserkserks/openboard/tree/master/app/src/main/jniLibs/arm64-v8a and then import it by opening the OpenBoard settings app, going to "Advanced", and then choosing "Load gesture typing library". Note: Google's library is proprietary and not open source.
Ok I understand the technical reality you poin to, I just refer to the user experience. For a normal user, you probably won't notice that technically manjaro is not arch and EOS is.
IMHO Manjaro breaks a lot and EOS just works and needs less manteinance.
