缺少i915固件是升级后常出现在的情况：
sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-6.7.12-amd64
W: Possible missing firmware /lib/firmware/i915/mtl_gsc_1.bin for module i915
W: Possible missing firmware /lib/firmware/i915/mtl_huc_gsc.bin for module i915
W: Possible missing firmware /lib/firmware/i915/mtl_guc_70.bin for module i915
解决：
从i915固件库中下载mtl_gsc_1.bin、mtl_huc_gsc.bin、mtl_guc_70.bin，拷贝到/lib/firmware/i915/文件夹中，执行update-initramfs -u -k all
