I had to disable Bluetooth in the BIOS, the system will only boot with hybrid and not discrete graphics, and WiFi required the fixed mentioned in above HCL entry.
Various reports seem to indicated, that USB-C docking stations have been found working (with reduced speed?) but I do not seem to be able to get the ThinkPad USB-C Dock Gen2 to jive with the system: neither web nor external screens work. Plugging it in does not do anything to udevadmin in either dom0 nor sys-usb.
As the laptop’s HDMI port also does not work (likely due to being hardwired to the NVDIA card), I currently have no means of setting up multiple screens.
I want to use Qubes and this machine as my daily driver and non functioning dock as well as the lack of a multiple screen options are show stoppers for this.
The latter is possibly fixable through NVIDIA support in dom0 and that’s what I’m working on next, but I would highly appreciate any hint on how to get the dock working.
Installing kernel-latest in dom0 (which currently brings in 5.16) and setting graphics to discrete in the BIOS renders the on board HDMI port active. Hybrid graphics settings results in a black screen when the display manager comes up.
Still having issues with the screens only being shown mirrored, but I’m getting somewhere.
No luck whatsoever with the USB-C dock. Pointers highly appreciated.
Does unchecking the “Mirror displays” option (in Q → System Tools →
Display) also work? If not, that’s a bug; please report it. If so,
that’s a user experience problem and should also be reported.

Installing `kernel-latest` in `dom0` (which currently brings in 5.16) and
setting graphics to `discrete` in the BIOS renders the on board HDMI port
active. `Hybrid` graphics settings results in a black screen when the
display manager comes up.
Interesting. I am on a P1 gen4 with a nVidia card (so, a similar hardware
config), and I simply cannot get any X when using the "discrete" UEFI setting.
In "hybrid" mode, initially `kernel-latest` here also meant no X. Only after
creating an `xorg.conf` file and *explicitly* setting "modesetting" driver for
the integrated card I got X to work with `kernel-latest`. X was working out of
the box with the original kernel though in "hybrid" mode (I am guessing some
timing changes leading to card initialization happening in different order or
some such).
HDMI ports refuse to work in X regardless of what I do. Tried the binary
driver, tried nVidia modesetting, tried nouveau. Tried "hybrid", tried
"discrete". To no avail. Best I got was the Qubes loading screen and FDE
password prompt on the external monitor -- both in "hybrid" and "discrete",
only with binary driver and nVidia modesetting.
Enabling nVidia binary driver and configuring it in `xorg.conf` always ends in
this line in `Xorg.0.conf`:
