There was a problem hiding this comment.
What if XDG_SESSION_TYPE is not set? Or alternatively, if the X11 connection is not configured properly (e.g. DISPLAY is not set)? The following is set on my Ubuntu 20.04 (in WSL), with the DISPLAY value being valid only when I do not forget to run my X server. I imagine the DISPLAY value could be invalid for other reasons as well.
$ set | grep DISPLAY
DISPLAY=:0
$ set | grep XDG
XDG_DATA_DIRS=/usr/local/share:/usr/share:/var/lib/snapd/desktop
local -a dirs=(${BASH_COMPLETION_USER_DIR:-${XDG_DATA_HOME:-$HOME/.local/share}/bash-completion}/completions);
for dir in ${XDG_DATA_DIRS:-/usr/local/share:/usr/share};
$I think a better option is to use a try-except block instead to prefer X11 over gnome-screenshot: #7143

Alternative to #7143
#7100 (comment)
For this reason, a later comment in the thread requested that X11 be preferred over gnome-screenshot.
This PR modifies ImageGrab to not use gnome-screenshot if X11 is in use and Pillow has XCB support.
