Opening PyCharm/IntelliJ IDEA terminal starts a new Xorg session

Question

I have installed PyCharm Community Edition 2017.2.1 and Arch Linux with Zsh as my default shell and i3 is my window manager.

When I open a new terminal window inside PyCharm, it starts a new Xorg session (exec i3 I think) and switches to a new TTY. When I come back to my main session with ctrl+alt+F1 I see these logs in the terminal:

When I set the shell to bash in settings it works normally. How do I make terminal behave as normal?

Answer 1

Go to File -> Settings -> Tools -> Terminal and uncheck the "Shell integration" checkbox and click OK. Terminal should behave as normal.

This is happening because when "Shell integration" is checked PyCharm (and IntelliJ IDEA) sources a .zshrc file located in the terminal folder under plugins of PyCharm distribution.

From https://www.jetbrains.com/help/pycharm/terminal.html :

Shell integration:

If this option is selected, the terminal first loads a custom rc config file (located in the terminal folder under plugins of PyCharm distribution) which provides an additional set-up, and then the user's rc file. Note that presently shell integration works for Bash/sh (bashrc), zsh(zshrc) and fish shell (config.fish).

An alternative solution is to comment out this code in /opt/pycharm-professional/plugins/terminal/.zshrc:

if [ -n $LOGIN_SHELL ]; then
  if [ -f "$DOTDIR/.zlogin" ]; then
       source "$DOTDIR/.zlogin"
