I've decided to report the issue here since it seems to be a kernel bug, and since Mint is based on Ubuntu where its kernels are built, I thought it'd be wise to report here and escalating to the LKML if necessary. Firstly, its display turns off when it boots, unless an external display is connected, in which case both displays work fine. But the backlight can't be controlled by typical programs (brightness buttons don't work, and xbacklight says 'No outputs have backlight property') apart from light (https://github.com/haikarainen/light); but that only works on kernels 5.15.*, not on 6.3.4, on that kernel only the brightness value changes, but to no effect. Upon bootup, I can see: uhci_hcd :00:1a.0: Found HC with no IRQ. Check BIOS/PCI :00:1a.0 setup! uhci_hcd :00:1a.0: init :00:1a.0 fail, -19 uhci_hcd :00:1d.0: Found HC with no IRQ.
