Thanks! I managed to install the kernel on laptop #1. I rebooted the kernel without the 'intel_iommu=igfx_off' parameter, and the screen flickers still.
$ cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-6.19.0-061900rc4drmtip20260107-generic root=UUID=c6b19f0f-68ff-4d8c-985a-c3ed88345389 ro quiet splash resume=UUID=f25913ea-6478-45dc-8f64-ea5d721a8f25 vt.handoff=7 I will later try with laptop #2 as well.
