Doh!...looks like I shot myself in the the realtime foot... was created by pferrick
Hi all-
In goofing around with pygtk, Glade and popup windows that refuse to go away, I very regrettably deleted a file which is important to the health and well-being of 2.7, namely:
Error: could not load module /usr/realtime-3.4-9-rtai-686-pae/modules/rtai_hal.ko: No such file or directory
Please tell me that there's a fix that does not require a full re-install!!
Thanks,
Patrick

Best is on this error
Go to bios
SAVE and exit and that is the Trick
it simply stuck in the realtime loader

Not sure I understand what you mean. Are you saying that some change has (or needs to ) happen to the BIOS??
If you could be just a bit more specific I would really appreciate it! Thanks.

can you post more of the error?
Unless you were using a sudo command you can't delete a file in there.

Well, I hate to admit it but sudo WAS involved. Basically I was experimenting with having windows appear via pygtk, and for a while some could not be gotten rid of, because I hadn't yet connected the destroy signal to the right place. And of course I designed them without a iconify/fullscreen/close bar across the top.
In the process of dealing with these windows, linuxcnc didn't start up as usual and it looked to me (at the time, anyway) that there was a file related to the realtime part of linuxcnc that was hanging around that shouldn't be. That's essentially what led me to mistakenly delete the file in question. Super dumb move, I know.
Anyhow, here's the whole error output:
and here's the contents of linuxcnc_debug.txt:
and finally, here's the tail end of dmesg:
(everything before this is I believe unrelated to this particular problem...)
Well, I've got my asbestos underwear on so flame away!
Many thanks,
Patrick

You might try this and see if it fixes it.
Open Synaptic, search for "rtai", then mark every thing in that search which was already installed for re-installation, apply, reboot and see if it works again.

It worked! Todd gets the gold star today.
Y'know, it's been said many times on this forum but I'll say it again: if ANY of you guru-types are ever passing through central NY (ie. the Syracuse area) you should really drop me a line. I would really enjoy heading out for a cold one and talking cnc, and you've certainly earned it! As a matter of fact, now I'm wondering what (if any) linuxcnc gatherings there might be in the works...now THAT would be a lot of fun.
Thanks again.
Patrick
