I have no experience with this, but just in case the variable is important. You have a typo in your grub.cfg

acpi_baklight
should be
acpi_backlight
You omitted the 'c'

Thx, I fixed it. Unfortunately, the problem still exists. =(

It looks like some trouble with video driver after suspend, but I don't know how detect it.
