Modify PATH for Desktop Enviroment on startup

cf flag
OS: Kubuntu 22.04, freshly installed.

I have script called test.sh:

echo $PATH
sleep 10

when I call it by clicking on file by mouse right button and choose run in Konsole the echo $PATH shows:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

but when I call it by firstly entering terminal Konsole and switching directory to directory of test.sh and then call it by typing command: ./test.sh then echo $PATH shows:

home/myuser/.nvm/versions/node/v16.18.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

  • there is a difference,

that is because i've installed something (node.js) before (in terminal by apt-get). As I understand, Desktop Enviroment has his own PATH variable, that is why that PATH (first one) doesnt has home/myuser/.nvm/versions/node/v16.18.0/bin part at the begining.

So I've decided to modify Desktop Enviroment's PATH manually. In order to do this, I've created a file called .xsession and fulfill it with:

#!/bin/bash

export PATH="/home/myuser/.nvm/versions/node/v16.18.0/bin:$PATH"

and I've put that file inside my home directory right beside .bashrc and .profile files.

As far as I know Linux will run this file when I log in to my user again. So I've logged out and logged in and tried calling test.sh by clicking on it and choosing run in Konsole from drop-down menu. But it shows PATH the same way as before, without my additional part.

I am using Kubuntu 22.04 and I saw autostart options in settings App, so I've added my script there also, but with different name because .xsession wasn't allowed there. Still after logging out and logging in nothing works as expected.

What else can I do to modify PATH of Desktop Enviroment on start? Did I sth wrong?

EDIT:

.xsession file is called, because I've added read command at the bottom of that file, and after logging in I see process running that file in process list. But why it does not modify PATH as it should?

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
