启动时执行 setpci

我在 MBA 上启动 Arch 时使用 grub 执行两个 setpci 命令。这些命令为我解决了“startx 黑屏”问题：

setpci -s "00:17.0" 3e.b=8
setpci -s "02:00.0" 04.b=7

现在我想摆脱 grub 并切换到 rEFInd。如何在不使用 grub 的情况下执行这些命令？我已经尝试过 /etc/rc.local + systemctl，但它似乎不起作用，启动 X 时出现黑屏：

$ cat /etc/grub.d/01_enable_vga.conf
setpci -s "00:17.0" 3e.b=8
setpci -s "02:00.0" 04.b=7

$ cat /etc/rc.local
#!/bin/sh
setpci -s "00:17.0" 3e.b=8
setpci -s "02:00.0" 04.b=7
exit 0

$ sudo systemctl status rc-local.service
