I believe the only thing missing to getting SQL Workbench working is by having your authorization agent of choice launched in your i3 .xinitrc file
Hi again! Thanks for replying! I don't know what do you mean and how to do this, would you like to help me with that?
I see!
I included it into the i3 config file (I saw that it was set up to execute gnome-toolkit (which isn't installed)), but after changing it to KDE's, it gets initialized when logging in, but it doesn't seem to affect Workbench
