Bug Description

If running --dedicated without X server it crashes with no valid video driver.

If running --dedicated with X running, a black window comes up, it does not fork (as mentioned in bug 1330068), and I can not close the window, and not close the process by ^C. After KDE brings up the Popup to close the program, deciding to close the program thrashes the X server (100% cpu, not responding anymore, no entry in the log).

hjd mentioned he was able to kill the widelands process. I do not know what KDE process killing does differently as this did not work for me. I did not try to kill the widelands process on the console.

I ran `ps -ef | grep widelands` and got the PID. I first tried `kill`, which didn't have any effect, so I had to use `kill -9`.

I know we have discussed dedicated and the need for graphics before. I could only find bug 1322869 right now, though I believe there was a related issue found by scan-build?

--dedicated is a hack build into the game because hosting is hard - opening ports and so on. The correct solution here is to make hosting easy (through the proxy we have discussed a few times already). I'd much rather somebody spent time in building this proxy than fixing dedicated.

The design of dedicated assumes that no Graphics() object is created. That means that everywhere g_gr is used and the code can pass by (many places) we now need a if (g_gr) /* not in dedicated mode */. That is fragile and has probably broken in the last 100 commits or so - since there are no tests it would not have been noticed.

I am not sure if dedicated even directly jumps into the game logic anymore - the code is super hard to follow.
