I have had a similar issue it was fixed by installing my GPU drivers from the manufacturer. But I went to my laptop manufacturer and found a complete linux driver pack with rpm and autoconf downloads.
Here is the link to the drivers page for your laptop but they have only Windows drivers. I also could not find third party linux drivers for your laptop. You probably have mesa nut it is a gnu compatible version of openGL I would recommend updating/installing other packages for mesa.
Sorry I could not be of further assistance.
okay lucio this is an unconventional fix but you could change this:
GRUB_CMDLINE_LINUX="quiet splash acpi_osi=Linux acpi_backlight=vendor"
in the file
this adds brightness adjustment but still no fix for the screen to turn on. it seems this is a very common issue with acer aspire series.
