## Description
|
|
|
|
Setup a GPU GUI domain named "sys-gui-gpu". The GPU is attached to the qube
|
|
and all graphics computation are handled by this qube. Requires a dedicated
|
|
graphics card (external GPU) and PCI passthrough support.
|
|
|
|
## Installation
|
|
|
|
WARNING: [unfinished formula](../../docs/TROUBLESHOOT.md#no-support-for-unfinished-formulas).
|
|
|
|
* Top:
|
|
|
|
```sh
|
|
sudo qubesctl top.enable qvm.sys-gui pillar=True
|
|
sudo qubesctl top.enable sys-gui-gpu
|
|
sudo qubesctl --targets=tpl-sys-gui,sys-gui-gpu state.apply
|
|
sudo qubesctl top.disable sys-gui-gpu
|
|
sudo qubesctl state.apply sys-gui-gpu.prefs
|
|
```
|
|
|
|
* State:
|
|
|
|
<!-- pkg:begin:post-install -->
|
|
|
|
```sh
|
|
sudo qubesctl top.enable qvm.sys-gui pillar=True
|
|
sudo qubesctl state.apply sys-gui-gpu.create
|
|
sudo qubesctl --skip-dom0 --targets=tpl-sys-gui state.apply sys-gui-gpu.install
|
|
sudo qubesctl --skip-dom0 --targets=sys-gui-gpu state.apply sys-gui-gpu.configure
|
|
sudo qubesctl state.apply sys-gui-gpu.prefs
|
|
```
|
|
|
|
<!-- pkg:end:post-install -->
|
|
|
|
The formula assumes Intel graphics card, if you have a card from another
|
|
vendor, please use
|
|
[qvm-pci](https://www.qubes-os.org/doc/how-to-use-pci-devices/#qvm-pci-usage)
|
|
to persistently attach the GPU with the permissive option to `sys-gui-gpu`.
|
|
|
|
Shutdown all your running qubes as the global property `default_guivm` has
|
|
changed to `sys-gui-gpu`.
|
|
|
|
## Uninstallation
|
|
|
|
Reboot you computer and prevent Qubes OS autostart of any qube, be it
|
|
`sys-gui-gpu` or the qubes connected to it to reach dom0. For that, you need to
|
|
boot Qubes OS with
|
|
[qubes.skip_autostart GRUB parameter](https://www.qubes-os.org/doc/autostart-troubleshooting/).
|
|
Only after you have done these steps manually, you can continue the
|
|
uninstallation procedure.
|
|
|
|
Set Global preference `default_guivm` to `dom0` and disable `autostart` of
|
|
`sys-gui-gpu`:
|
|
|
|
```sh
|
|
sudo qubesctl state.apply sys-gui-gpu.cancel
|
|
```
|
|
|
|
## Usage
|
|
|
|
Qubes that have their `guivm` preference set to `sys-gui-gpu`, will use it as
|
|
the GUI domain.
|
|
|
|
The process to enter `sys-gui-gpu` can be a simple logout, but on most
|
|
platforms, a reboot is required and recommended to prevent data loss.
|
|
|
|
The login credentials are the same used in `dom0`, the first user in the
|
|
`qubes` group and the corresponding password.
