On boot, press Esc to get the language-selection screen. Press Enter to select English. Press F6, which gives you a menu. Press Esc to dismiss that menu. Then you can use the arrow keys to edit the Boot Options and (e.g.) add "nomodeset".

If "nomodeset" doesn't give you full resolution, you could try deleting "quiet splash --" and adding "drm_kms_helper.poll=0". If that gives you full resolution but with no brightness control, you could try deleting "quiet splash --" and adding "drm_kms_helper.poll=0 acpi_osi=Linux acpi_backlight=vendor" (or maybe "legacy" instead of "vendor").

My machine is a Dell Vostro 360, so I'm not sure how applicable my observations are. But I've recorded them at "Linux in full HD (with brightness control) on Dell Vostro 360".
