Using xdg-open to open file make dolphin opened first

English Applications
1

Hi all, I got problem opening any file from eg: chrome, which called xdg-open to open specified file. It called out dolphin first and then used dolphin to handle the opening of file. And after opened the file, dolphin was left there and had to be closed manually. How to open the file directly or handle the opening of file through dolphin and closed automatically after opening the file?

Here is my system info gethered using inxi -bI:

I tired to track what xdg-open does and found that it handles the input to kde-open to open these files.

 ❯ xdg-open ~/2023-02-13-23-01.png
+ check_common_commands /home/ddqi/2023-02-13-23-01.png
+ '[' 1 -gt 0 ']'
+ parm=/home/ddqi/2023-02-13-23-01.png
+ shift
+ case "$parm" in
+ '[' 0 -gt 0 ']'
+ '[' -z '' ']'
+ unset XDG_UTILS_DEBUG_LEVEL
+ '[' 0 -lt 1 ']'
+ xdg_redirect_output=' > /dev/null 2> /dev/null'
+ '[' x/home/ddqi/2023-02-13-23-01.png '!=' x ']'
+ url=

+ '[' -f /run/user/1000/flatpak-info ']'

+ return 0
+ case "${BROWSER}" in
+ case "$DE" in
+ open_kde /home/ddqi/2023-02-13-23-01.png
+ '[' -n 5 ']'
+ case "${KDE_SESSION_VERSION}" in
+ kde-open5 /home/ddqi/2023-02-13-23-01.png
+ '[' 0 -eq 0 ']'
+ exit_success
+ '[' 0 -gt 0 ']'
+ exit 0

So this behavior is actually as expected?

I finally managed to solve this… The following are steps to find solutions:

  1. The file handler is related to mime type under ~/.config/mimeapps.list. So create a new user to recur this problem may help.
  2. Create a new user. Create sample files. And open them with kde-open.
  3. kde-open gave out errors:
kf.service.services: KApplicationTrader: mimeType "x-scheme-handler/file" not found
  1. So x-scheme-handler/file must be set , which is the problem.

And I found these lines in mimeapps.list. After remove theses lines things are finally normal.
