Go figure... I'll try again.

And now it does not crash! Weird. I'll wait to see what happens to the display.

No crash, and it works: my display doesn't go to sleep. Success!


Success of a kind... I actually would prefer the display to go to sleep, the problem is that it never awakes :-/


I found another problem. Yesterday night, before leaving for bed, I closed the lid for a minute while I moved the unit. Well, it suspended, which I was unaware of till this morning:

I found out this morning when it did not respond to pings. Of course, the display was dead, and it did not respond.


But it was very hot!

The fan was blowing full time, the CPU was HOT. What kind of 'suspend' is that, with the CPU warmer than when running normally!


The laptop sits with the bottom cover removed, on top of a blower unit plugged to a mains-usb power converter, so cooling is as appropriate as can be.


I'm trying to avoid suspend with a inhibit script in /etc/pm/sleep.d/.
