Python runs headless on Linux until I manually set DISPLAY #120067

Issue Type: Bug

Whenever I exit vscode and come back in, matplotlib doesn't produce any display. Attempting to set the backend elicits a message saying that I am running headless. If I open a VS code terminal window and export DISPLAY=:0, then plotting works until the next time. Disabling extensions (except Pythion) does not make a difference
