htop showing duplicate applications with very odd bizarre results upwards of 20,30,40 or more, see screen grab

Solution 1:

What you're seeing is perfectly normal. If you'd like to have an easier view on the eyes (that still shows correct information) you can perform the following steps in HTOP:

1. Press F2 to enter the Setup menu.
2. With "Setup" selected on the left, press the down arrow until you have "Display Options" hilighted.
3. Press the right arrow (->) to move the cursor to the next column and press the "space" key to select "Tree View".
4. Press the down arrow and select "Hide kernel threads" by pressing the "space" key.
5. Press the down arrow again and select "Hide userland threads" with the "space" key.
6. Press F10 to save your changes.

What you are seeing by default is a representation of all of the kernel and userland threads being reported. By following the above steps, you'll not show these threads and have a cleaner view of the running processes on your system.

If you'd like, here is what I have in my ~/.config/htop/htoprc file:

# Beware! This file is rewritten by htop when settings are changed in the interface.
# The parser is also very primitive, and not human-friendly.
