As a temporary workaround (at least for me, Toshiba Z830) I:

- removed "acpi_backlight=vendor" in the boot parameters (which I was using in the past)
- Used the program "light" available in AUR to control the brightness (with appropriate global keyboard shortcuts)
- added this -> light `light -c` <- in a hook in /usr/lib/systemd/system-sleep to execute it right after wake up to restore the brightness.

Tada! The screen turns on and the brightness can be controlled with the keyboard shortcuts.

I can confirm the bug in 3.8.3-2-ARCH, too.

acpi_osi='!Windows 2012' in grub seems to solve the issue
