Black screen when resuming from hibernation

[ysalmon]

Hello, sometimes, when I boot my computer after having hibernated, TuxOnIce 4.4.0-31 proceeds to restore the RAM in its former state, but instead of proceeding to the X session, the monitor goes to sleep mode (other devices, like my USB mouse, also become unpowered). When this happens, I cannot do anything else than powering the computer off then on again (Alt-SysReq REISUB does not work, presumably because the USB keyboard is also not powered).

This happened today, and, to be sure, I tried to resume from this image 3 more times, and the behaviour was exactly the same.

This has been happening more frequently than in the past, so I tried with an earlier version (4.4.0-24), and it also happens with it.

It might be the case that this behaviour is triggered or aggravated when a Steam game has been run during the session (or even just the Steam client). Indeed, I have been using this more frequently for a month or two.

I would like to attach logs, but for a reason I do not know, /var/log/pm-suspend.log et al. only contain information about what was done in March.

I take bake the hypothesis about Steam et al. as today the problem appeared without it having run.

An update on this problem :

• when the monitor goes into sleep mode, I can (quite often, in fact) manually switch to virtual terminal 1, then the display works again, then I can switch back to the lightdm login screen on VT 8.
• the Ubuntu standard kernel does not behave like this anymore ; when resuming from hibernation, the NVIDIA logo (from the proprietary driver) briefly displays and the lightdm login screen shows up.

I realize that since I opened this issue, I have got a new machine ; lspci is now
