Finally got it to work, I followed this solution from the previously mentioned askubuntu thread:
sudo gedit /etc/default/grub Replace GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"With GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pcie_aspm=force acpi_backlight=native”
press ctrl+s , close the text editor sudo update-grub (did "sudo grub-mkconfig -o /boot/grub/grub.cfg" instead)Then reboot your system.
