> You have good taste in laptops. :) Haha thank you, as do you, the T14 was second on my list, yeah I suspect there will be plenty of Qubes users on these devices they tick a lot of boxes, I've never used Qubes with >4 Cores so it'll be a nice experience.

Hmm, wonder if I should try building a 4.1 ISO with a Linux 5.8 Kernel, it's interesting because Xen is able to write to the framebuffer just fine, I think it's dom0 that isn't able to remap it so it stays at an address Xen had it configured for, it almost smells like an IOMMU/Memory Mapping issue, not necessarily GPU. There's UEFI Options for the UMA Framebuffer size of 512MB, 1GB and 2GB I've tried all variants unsuccessfully. I don't think it's a Xen issue because I tried simply moving my current laptop's NVMe, when I entered my LUKs Password (Blind) I could see LEDs on the keyboard initialize so I think 4.0.3 does indeed work fine. I don't think there's a migration path for 4.0.3 - 4.1 (Backup & Restore) yet, I don't think the Qubes team have even signed any 4.1 ISOs yet either so I'd rather 4.0.3 but I'll take anything I can get at this point.
