I am using X11/Skia ui for LibreOffice on Linux. Version: 7.6.0.0.alpha1+ (X86_64) / LibreOffice Community Build ID: c01639c556276e496d9e762468cad6b27f9ed0f4 CPU threads: 12; OS: Linux 5.19; UI render: Skia/Vulkan; VCL: x11 Locale: en-US (en_US.UTF-8); UI: en-US Calc: CL threaded By enabling Skia, and having "Force Skia software rendering" unchecked, I can see Skia log using "Copy skia.log" button: RenderMethod: vulkan Vendor: ... Device: ... API: ... Driver: ... DeviceType: integrated DeviceName: Intel(R) Graphics (...) Denylisted: no I have a dual Intel/NVIDIA GPU installed, and now it is using Intel integrated GPU with Vulkan renderer. But, it should be possible to tell LibreOffice to use specific GPU. In Vulkan C++ examples, I see that the binaries take a -g/--gpu command line argument, so that you can tell them which GPU to use: https://github.com/SaschaWillems/Vulkan I think having such an option in LibreOffice would be useful.
A similar request from someone using LibreOffice on Windows: How can I have Skia/Vulcan engage the Nvidia GPU on my notebook? https://ask.libreoffice.org/t/how-can-i-have-skia-vulcan-engage-the-nvidia-gpu-on-my-notebook/69440/11
I have generalized the feature request to "provide an option" instead of asking for a command line option.
