Today my laptop won't recognize any external screen. I use arandr. It's not detecting any of them (I have 2)
I tried other screens, rebooting, rebooting in kernel 4.19 (I use 5.4). without success.
also I don't think it's related to an update, I have rebooted a few times since the last one.
Any idea where I can look? I have no idea where to find logs or how to debug this further.
Thank you so much in advance.
