rpib runniing bookworm. Private net. rt-preempt kernel. Security is a 
closed garage door and lead projectiles for unwanted guests.

xfce4 desktop, running linuxcnc, which controls all 255 volt power to an 
11x56" lathe with several horsepower at its disposal. New install, came 
across a dangerous situation yesterday.

Basically using the lathe as a jig to hold a long piece I was tapping by 
hand, powered up but stopped. screen blanker came on and locked me out 
till I logged back in leaving linuxcnc live but hidden behind a black 
screen.  This is a dangerous condition if he wrong key is hit to wake it up.

That monitor AND the idling rpi4b draw about 22 watts, and is turned off 
only for maintenance.  UPS, standby generator, uptimes might be years.

Replacing a CRT power hungry monitor means the only reason to blank a 
screen and interpose a login is security against prying eyes in an 
office environment.

Soooo, what do I remove to absolutely, permanently disable the screen 
blanker? And I mean no chance it can ever do that to me again.

Thanks.

Cheers, Gene Heskett, CET.
