--- Comment #5 from Sylvain BERTRAND sylvain.bertrand@gmail.com --- I cannot reasonably tell you if it is a regression, because my usage rarely gets my monitor in dpms off mode. That on top of the fact I did a new custom gnu/linux distro recently. If you have some compilation or not flags to enable tracing of video mode related code (in any/all components), I'll give it a shot.
I must say that the keyboard and mouse are responsive and I can use the computer blindely when the monitor is looping in trying to restore the video mode, thus I am able to get on the spot logs.
