Does the display work at startup? Like does it POST and do you have a boot loader? Do you have another device that you could use to check that the cable and monitor are not the issue? What graphics card are you using and which driver? And change to kernel or initrd? Awhile ago I believe xf86 video intel was deprecated in favor of mode setting. Are you using UEFI?
