Thanks for the tip! KeepassX works great, but the author(s) don't seem to bother with pull requests and therefore useful features like keepasshttp or autotype won't get implemented. Keepass 2.x with mono never worked for me.

Autotype works just fine for me on KeePassX, do you have the latest version (2)? You also need the appropriate x utilities installed.

Can you explain which appropriate x utitilies are needed? Tried that several times but never got that working.
