I start my laptop up and it hangs during boot at

ACPI: Video Device [VID1] (multi-head:yes rom:yes post:no)

I've already tried setting the kernel boot parameter nox2apic:

GRUB_CMDLINE_LINUX_DEFAULT="nox2apic"

but it slows the system way down and I can't play my steam games. Would installing drivers other than the nouveau drivers fix the problem and speed it back up?

My machine is a ThinkPad T420 running 16.04

@JeffyJefferson: Why is it not a duplicate of the question linked by Pilot6? Did you try its (applicable) answers? What happened for each of them when you did? – David Foerster Jun 11 '17 at 22:29
Could you please try some of the other answers in the linked question? The nomodeset option is very promising in general. Which graphics adapters does the computer in question have, i. e. what's the output of lspci -nnk | grep -A3 VGA? – David Foerster Jun 18 '17 at 08:58
