Keyboard and Mouse become unresponsive in AXIS.

I mentioned this before.

LinuxCNC (2.8, AXIS, Ubuntu 20.04, Intel Duo core with isolcpus=1, Mesa 6i25, open-loop stepper system) is executing a program.

To amuse myself while it's running, I'm zooming, rotating, dragging, etc. the model in the AXIS window when--just like that--AXIS stops responding to mouse AND keyboard inputs. It doesn't seem to be a buffer issue that recovers later. They never seem to come back.

Meanwhile LxCNC continues running the program just fine.

The most troublesome thing about this is that F1, F2 and Esc are all ignored: no E-stop from the keyboard.

If AXIS is full-screen, I can't minimize it to get to anything else. (I didn't think to try Ctrl-T to open a new terminal.)

I finally opened a new (what's it called: "terminal") with Ctrl-Alt-F5 [so THOSE keys were honored] and logged in and ps'd and killed every linuxcnc routine I could find.  When I went back to the original terminal and restarted LinuxCNC, keyboard and mouse worked fine.

Has this been seen before?

Is there a recovery procedure?

I'd hate to have to kill and restart over this.

You Linux gurus, could I do something like restart the workspace manager, display manager or desktop, or something like that? (I don't even know what I'm saying...)

Thanks.

:thumbsup:

Thank you. BOTH graphics card AND memory sticks are questionable in this old Dell 780.

As it was, I ran the million-or-so lines of G-code and didn't amuse myself by fussing with views, and it came out fine, if a little off-center, but I think that one's on me.
