Also, you'll have to specify the inifile directly on the commandline; the configuration chooser is graphical only.

Re: [Emc-users] Run Keystick Without X
In emc 2.2.x, the emc script always tries to create a terminal to run keystick inside. In the development version, this has been changed. keystick will start with DISPLAY unset (I just tested this with configs/sim/keystick.ini). Here's the main change that made this possible: http://cvs.linuxcnc.org/cvs/emc2/scripts/emc.in.diff?r1=1.81;r2=1.82 I don't know for sure if that will apply to 2.2, and I chose not to apply the change in 2.2 because I did not want to risk breaking the run scripts for any users for whom it was currently working. You may also need this change http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/src/emc/usr_intf/keystick.cc.diff?r1=1.9;r2=1.10 which I believe fixes an error in keystick at startup due to a kind of race condition. I'm pretty sure I didn't apply this to 2.2 either.

Not many people use it, so it may have bitrotted some. Last I tried it it ran pretty ok (as ok as it can run after that many years, and lots of emc2 redesign). It only supports 3 axes iirc, so anything beyond that won't work. Another gotcha you need to take care is that in the emc runscript (/usr/bin/emc) there is a switch statement based on the GUI used. For keystick it used to run xterm and keystick inside it (it causes some font/display issues if we run it in one of the other X terminals that are installed by default on debian and Ubuntu). You might want to change the reference to xterm (running no X won't allow you to run xterm :D).

One quick check is to hit Ctrl/F3 or one of those function keys between F1 and F7, these all bring up glass TTY screens without X services. As long as it responds to the basic cursor control sequences to move to specified rows and columns (which these screens do) then the curses package should handle the screen display. > Why would I want to do this?

Ubuntu and other Debian-based systems use both runlevels 2 and 3 as "multi-user, graphical" levels. "Standard" UNIX usually uses runlevel 2 as "networked, non-graphical". To prevent X from running, you can disable GDM from running by renaming the file S##gdm to K##gdm (I don't know what the ## will be, but it's a 2-digit number) I don't recall how much more you need to remove, that may be all. You should probably change the DISPLAY to "keystick" in some config and try it in a gnome terminal before fiddling with your system configuration. If you're in a console login and don't want X to load when you run EMC2, you need to specify the path to the ini file on the command line. (I don't know the specific syntax, I never do this ;) ) If you last ran a keystick-using config (even in a gnome terminal), you can also type "emc -l" (no quotes) to run the last used configuration. I believe (but I'm not positive) that this will bypass the graphical config chooser. >>Why would I want to do this?

Re: [Emc-users] Run Keystick Without X
If you had another machine somewhere with a graphics display, even a Winders box running an X server, the X client (on the EMC) machine could display there. I think what you are asking is can you run without X at all? Someone else will have to answer that definitively, but I think it currently needs AXIS running somewhere. It would be nice if there was a character (CURSES?) based version without the nice 'display' of the real time motion. And possibly there is, I just don't know about it. Or were you wanting to run 'headless', without Axis or equivalent at all? (I think of something like the CarveWright, that you can't do much more than stop/start it, everything else is pre-canned on another machine!)
