If you add a config option like this, then the user must somehow know, that when using this particular plugin, he should set this other config option too. That seems cumbersome, because the plugin itself certainly knows if it supports an input method or not. Why should the user be second-guessing the plugin? Rather than this new config option, I would be much happier seeing the shell plugin directly indicating whether it supports input methods or This could be realized by the shell plugin initializing the input method directly, or iff that's too complicated, perhaps something like a weston capability bit set by the shell. Is the only reason for this patch to avoid the errors at startup, or are there other reasons for users wanting to disable the input method even when the shell plugin does support it? If you really need a config option, how about setting [input-method] "path" explicitly to empty to disable loading the input method client? Thanks,
