12.04 Pure Simulator no longer starts

12.04 Pure Simulator no longer starts was created by Bryan_W
Short version -
Followed the wiki for a pure simulator install yesterday and (much to my surprise) was able to at least get to the axis gui after the "linuxcnc 2.6~pre" image popped up and a "manual tool changer" message popped up. However, each attempt at running any gcode left me with a "Program exceeds machine maximum on Z axis" message.
Today, ater googling, I started "playing" with homing and touching off per some suggestions in the forum.
Unfortunately, my computer crashed (gui disappeared and gave me a screen full of text that ended in - "Panic occurred- switching back to text console" ) while the simulator was running and I ended up having to power down to get out of it.
After restarting the computer the simulator will show startup image and "tool changer" message, but then shuts down.
So, (me) being a wiz at git and compiling after one day, I tried each of the following but the program still shuts down:
ran dpkg-checkbuilddeps (which came back clean)
ran "make clean" in git/linuxcnc/src.terminal
ran make
My question is, can I get the simulator back without a fresh install of 12.04?
Thanks in advance,
Bryan

Just thought I'd report that I have the simulator running again - I re-cloned the git and recompiled.
Now I'm just back to working on the "Program exceeds machine maximum on z axis" message problem.

That's not a problem... it's telling you your trying to move outside your configured boundaries.

I'm having this same issue (at least it sounds the same).
I'm running 12.04 Ubuntu on a 32 bit machine. A few days ago I succumbed to the repeated notifications from the system that "Updates were available" and click "Oh, OK, go ahead and update the darn thing!"
Before I did that I had a working sim version of EMC 2.5. After updating Ubuntu, it no longer works. The toolchanger screen pops up, and the terminal reports a few "waiting for s.axes" before quitting.
Rather than try to get to the bottom of that, I thought I'd go ahead and load new source, build it, and go from there. I followed the directions here and things seemed to go correctly. But I only get the splash screen (2.6.0~pre), the toolchanger screen, and then a crash.
Here's the terminal output:
And here's what's in linuxcnc_debug.txt:
and, finally, what's in linuxcnc_print.txt:
This is my first post here, so please tell me if I'm posting inappropriately in some way! I've been using EMC (now linuxcnc) for 7 years and it has been a huge help. Normally I can get to the bottom of problems with searchng on these forums or on the wiki. I think my problem this time is trying to use the simulator on a new-ish version of Ubuntu.
Thanks in advance for any pointers!

Try sim-tklinuxcnc if that works then it is definitely a graphics problem.

Thanks, Andy Pugh: Its working now.
I wasn't able to run the tklinuxcnc simulator, either. But your tip about it being related to openGL sent me in the right direction. Synaptic showed me updates related to my AMD graphics hardware and, when I installed those, the axis-sim is again working.
I really appreciate your help.
