Ethan Shalev,

for GRUB2 the file is /etc/default/grub
then "sudo update-grub" (no quotes) to apply changes

my changed line looks like
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="

As for non-persistent check, when the GRUB boot menu comes press the key
'e', and modify the boot parameters from there. Look for "quiet splash"
and add acpi_osi= after that.
