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`: > Failed to allocate push buffer What a mess! -- Best, rysiek -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
