Win qubes and sys-gui-gpu

[tempmail]

I never tried in 4.1 because I didn’t have a need, but now under 4.2 I am desperate to have Win 10/11 qube fully functional.

So I set for Win 7/10/11 guivm to be sys-gui-gpu. They start, but no gui for any. Neither choosing specific application from the menu to start (Wordpad, for example) helps. Just silence while green dot behind their name in sys-gui-gpu Qube Manager… Funny.

Has anyone, including devs (@marmarek) tried and succeeded to run Win qubes in sys-gui-gpu actually?

sys-gui-gpu is purpose is to manage Qubes OS from a qube and detach the GPU from dom0 to reduce attack vectors.

it is not supposed to be used as a regular qube to have GPU available, for instance sys-gui-gpu does not have network access, like dom0.

I never said something like that. I’m using sys-gui-gpu for 2 years probably, but never Win qube in it.

[Workaround] How to use external monitor in NVidia Optimus mode

For dual Intel/Nvidia GPU notebooks, as I understand it’s not possible to use external monitor/TV while in Nvidia Optimus mode because HDMI/DP ports are directly tied to Nvidia card. So we are doomed to Discrete mode, meanning using only Nvidia card which is very bad for the battery, or… Here I discovered that I can create sys-gui(-gpu) and attach only Nvidia card to it in Optimus mode even without hiding it from the dom0 and sys-gui-gpu is passed to external monitor, while using iGPU on the la…

GUI domain

My question is specific: has anyone tried to run Win qubes in sys-gui-gpu, because I can and have a whole set of Linux qubes succesfully running in sys-gui-gpu.

My apologies, I did not understand your question correctly the first time.

I can confirm a qube with Windows installed in it does not display in a sys-gui-vnc either, although it works when using dom0 for display. My sys-gui-vnc works fine as all my AppVMs are displayed.

Yeah HVM qubes don’t display in sys-gui session for me , I have tried in 3 devices and filed a GitHub issue for the bug few days back, is that the case for everyone here? I mean does Ubuntu or any other HVM not show it’s GUI under sys-gui session? PVH mode VMs Which are Linux based here work fine.
I can still access Linux HVMs using xen console from qubes manager but that’s not a real GUI

Issue tracking for HVM qubes not having a GUI under sys-gui

You can also report the status or any relevant information on that GitHub issue if it’s relevant to all HVM machines, otherwise it’s possibly different.
I didn’t know that it affected sys-gui-vnc and sys-gui-gpu , but I suspected so.
This would help developers to know more about the issue to fix it

Unfortunately, there are bigger issues with Win qubes (qwt under 4.2), that are adressed long time ago there, but to no avail.
