[Feature Request] Could you add "Run with Nvidia" to Cinnamon menu for nvidia-prime's new on-demand mode

[kelebek333]

Hi,

Could you add "Run with Nvidia" to Cinnamon menu's context menu for nvidia-prime's new on-demand mode. This feature is already available for Bumblebee on Cinnamon menu, so it can be easy to adapt it to nvidia-prime's on-demand mode.

Feature can be activated according to output of the command below and application can be run with the nvidia-optimus-offload-glx command.

on-demand

You can look following link for cross distro solution. Gnome Shell's switcheroo-control feature can be implamanted to Cinnamon

Yes , in fact that DRI_PRIME variable was only working with OpenGL apps , while Vulkan ones within DXVK context always picks up gpu1 automatically ( not 0) , native game ports like Feral Interactive offers a device selection on their launcher but games like Doom 2016 etc were problematic in this regard and it was only possible to use dgpu on AMD systems with layers like this.

However , with Mesa 20.1 this is not a problem anymore since this commit.

So extending this " Run with dgpu ( nvidia ) " feature to AMD systems also would be great.

I'm aware Mint 20 probably won't be shipping with Mesa 20.1 but since people does gaming on Ubuntu based distros are used to add ppa's to their systems for staying up-to-date , it won't be a problem.
