No video after hybernation

[Mijzelf]

Yesterday I updated my Dell Inspiron Mini 10 (Atom, GMA500, ... ) from Mageia 3 to Mageia 4. And now I have a problem. The laptop runs fine, but after restart from hybernation (suspend to disk) the screen is off.
I can see the grub menu, then the kernel log, and a part of the userland log. Directly after loading the hybernation file the screen switches off, and so far I found no magic key combination to get it alive again.
Aside from this the box boots normally. I can login over ssh, and see all processes running.
After poking around in the /sys directory and echoing '1' and 'on' in several files (like /sys/class/backlight/acpi_video0/bl_power) the screen suddenly waked up after I touched the right ctrl. Unfortunately I couldn't reproduce that.

Another problem, maybe related, the backlight doesn't switch off after some idle time anymore, which it used to do.

GMA500, like in Poulsbo?

Please show the output of

Yes, indeed.

Meanwhile I found that the problem doesn't always show up. My laptop once woke up from hibernation normally.

I have a dmesg trace of a 'problem wakeup':

You should take a look at https://wiki.mageia.org/en/Mageia_3_Err ... regression and maybe play around with acpi/apic kernel options.
