Feature request, but must be universallly accepted by ALL blanker authors

[Gene Heskett]

Greetings x-people;

The LinuxCNC people have just brought it up from Debian wheezy to buster 
for a base install.

But the security paranoia is going to get someone maimed or killed.

Someone has decreed that the screen blanker must be subject to a new 
login before anything can be done about a runaway machine with enough 
horsepower at its disposal to kill.

I have now been 3 days looking for a way to disable this blanker, trying 
several methods by way of xset, only to find 15 minutes later that its 
been undone and the blanker kicks in regardless.

So I am proposing that an env variable be named an agreed upon name, and 
that its presence totally disables any and ALL screen blanker's 
regardless of whose desktop of the day is installed.  We can incorporate 
the setting of this, on launching LinuxCNC, and unsetting it when 
LinuxCNC is being shut down.

If you agree that safety overrides paranoia, please consider this as part 
of the supplied X11 implementations.

In the meantime, since xset seems powerless to disable it, can someone 
tell me how, in xfce4, to disable it. Haveing it kick in in 10 minutes, 
while the machine is carving a part, and a miss-command does something 
wrong that needs to be stopped as quickly as possible, having a locked 
screen requiring a login via a swarf covering equipt keyboard is simply 
dangerous to both the operator and the machine.  So I'm asking how do I 
get rid of it, totally.  We can operate a monitors power switch if we 
are done for the day, but we can't tolerate anything getting in the way 
of controlling that runaway machine with one keystroke during the day.

Please advise.  And thank you.

Cheers, Gene Heskett
