Remarks

To make Qubes OS run on this laptop, I had to:

  • change SATA Operation mode from RAID On to AHCI, otherwise no disks were detected by Anaconda
  • make sure that dom0’s Linux commandline has the options nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off set, otherwise hard lockups and forced restarts were presents
  • for extra security, I decided not to automatically accept USB keyboards and mice during the initial setup: the touchpad and touchscreen are USB devices, but the keyboard is not, meaning that once logged in, I can just manually accept the touchpad and touchscreen with the keyboard once dom0 prompts me

Some curiosities unrelated to Qubes OS, but might be worth mentioning in case someone else has the same configuration and wonders if these are Qubes-related bugs:

  • the touchpad, i.e. Interlink Electronics Inc. VersaPad doesn’t distinguish between clicking the left button and tapping on it, i.e. tap-to-click toggling doesn’t exist and tap-to-click can’t be turned off
  • rebooting doesn’t work at all and causes a software lockup of some sort, shutdown your system and start from a powered off state instead

Software lockup before Firmware/BIOS (in the shutdown process of the existing session). or at the boot after soft restart (GRUB? Plymouth?)?

During the shutting-down part of an attempted reboot, the laptop does not power off and instead idles with a backlit display.
It’s not a Qubes OS bug, as this happens even if trying to reboot from firmware settings, but wanted to mention it just in case someone thinks it is a Qubes OS bug and files a ticket.
