It sounds like it does work, but something else is changing the
settings on you later on.
I don't think you've said how long your change works for.
Well, I'm not too sure. Right now it feels intermittent
and unrepeatable, at least with a value of 255 and/or 254.
And I've tried using a 60 second interval 'touch' with those values.
Some times the touch prevents the unload/load,and sometimes it doesn't.
Again, I need to attempt a scientific analysis.
Today I've been trying 253 with the 60 second 'touch', and that HAS
worked for 24 hours, so I declare that my official workaround
(pending better test results).
I don't recall you saying what desktop you use. It may help people
narrow down what might be periodically undoing your setting.
I use KDE, but there may be a few Gnome utilities/apps also installed.
(And this is Fedora 26)
