I would describe N900 behaviour as sane: you have sshd running, you are on a network with IP assigned, whether your screen is on or off people on the network can come and say hello through SSH.

Jolla behaviour is a bit insane, same setup: if your ssh connection hit before screen went dark all is fine and good (until you try to ./configure/make/sudo something), but after screen goes dark (might need an extra minute or two to reproduce) no way to connect.

Does anybody know how to make Jolla more sane in such situations?

edit: This supposedly could help (from irc when asking if screen on could be faked):
Workaround by keeping screen on, but will be horrible on battery. Any other way?
