I can agree this. More curious, after I install the nvidia blob I have
leave my laptop inside the dock, so I don't run with battery power and
don't see the bug again. With let me think it was caused by nouveau.
I've give it a test and pulled it out to run with battery power, and
after 5 minutes or less/more the screen turns black. So I guess this
is relay a power management issue as Bob mentioned and not a X driver
one.
