Like on lxqt when you insert a usb key and it shows a dialog.
I use nemo as file manager and independent WM (bspwm).
https://github.com/coldfix/udiskie the closest thing I can thing of.
also a simple script that looks at udev event would do.
Is it supposed to open a notification that clicked opens the file manager?
For that you'd need something a notification daemon as well. Assuming bspwm doesn't have one.
A quick search throws up https://github.com/dunst-project/dunst
You might get more specific ideas here https://old.reddit.com/r/bspwm/
In fact searching 'usb' on the sub produced this
https://github.com/carvalhudo/usb-rofi
Which, from a quick scan, seems to do what you want ?
I use dunst but clicking doesn't open the file manager.
I tried lxqt live and there it was so.
Maybe it use udiskie and dusnt too.
Do I need to configure it?
I'll look usb-rofi thanks.
I can click on udiskie tray to do that though and it automounts fine.
If you're willing to change your file manager, doublecmd has inbuilt support for managing the ext mount stuff without (to my knowledge) anything running, except for dbus of course. They will just pop up in the top right corner.
On nemo they pop up too, in Devices menu.
I found out the problem I need to use middle click to perform the action with this config.
I copied one from internet.
