I have installed fvwm on my latest ubuntu installation, but don’t have a clue how to get it to work. Definitely not as obvious as on 14.04
Can anyone give me some pointers please?
You should ask ubuntu support. If using a display manager there should be an fvwm session listed you can select, or add ‘exec fvwm’ to your ~/.xsession file. That is what is needed in debian at least.
