Ive found a solution.

just open ubuntu normally and open terminal

write:
sudo edit /etc/default/grub

then find this line:
GRUB_CMDLINE_LINUX ""

then make it like this:
GRUB_CMDLINE_LINUX " i915.powersave=0 "

then save , then back to terminal and write:
sudo update-grub;

Regarding Peter's suggested solution, the correct syntax would be:

GRUB_CMDLINE_LINUX="i915.powersave=0"

Otherwise, update-grub returns an error.
