Hi, currently i’m encountering a very strange problem with my ubuntu 24. On my second monitor, it will be shuttering and laggy for 3/5 time when I boot up my laptop. The lag will go always if I plug out and replug the monitor back in (obviously not the best way to fix this). However, this problem also tie to another problems that i havent been able to fix yet. When the display is being laggy, i can shutdown normally. If not, the laptop will be boot into the grub instantly after i shutdown. my current grub config

GRUB_CMDLINE_LINUX_DEFAULT="text irqpoll xhci_hcd.quirks=270336 amdgpu.runpm=0"
