I’m having problems finding your original request for support in this forum. All I can find in your user activity (All - Activity - wtechgo - Manjaro Linux Forum) is a tutorial you posted ([HowTo] Getting NVIDIA Geforce GT740m working on Manjaro with mhwd and Bumblebee390xx) and the above post.
Why do you consider this community to be unhelpful if you (apparently) never requested help in the first place?
