Passing noacpi results in similar results (screen flickering on movement, launching fullscreen video causes black screen) though no errors in dmesg.
Passing acpi=off results in normal operation (screen doesn't flicker, launching fullscreen video is fine), however, dmesg gives "vgaarb: this pci device is not a vga device" and the secondary screen does not work.
