Fedora 34 & Looking Glass on ASUS Zephyrus G15 Laptop

Hi All,

I have an ASUS Zephyrus G15 Laptop with an AMD iGPU and NVIDIA dGPU. It’s running Fedora 34 and uses GPU pass-through of the NVIDIA dGPU to run Windows 10 guest for gaming and other things. I am using Virtio drivers as well. Output config in my XML is through the usb-c port that is connected to the dGPU. So I use a USB-C to HDMI adapter to connect to an external HDMI display and it seems to work pretty well.

However, I also want to be able to be able to view the output from the guest OS on my Fedora host through a window, but I want to preserve most of the performance I am getting with the external HDMI display. Can I achieve this with the Spice monitor somehow? Or will I get better results with Looking Glass?

Right now, my setup is such that the output goes to external monitor and requires a separate keyboard and mouse from the one used on the host.

With Looking Glass, will I be able to use the same keyboard and mouse as host?

Secondly, what are the latest install and setup directions, and are there any for Fedora 34?


Provided you’re not running 4K on the laptop it should work well. LG is memory bandwidth intensive and the shared system ram that iGPUs use limit the performance of LG on laptops.

You need LG, the spice monitor will give no 3d acceleration as it uses the virtual QXL video device.

Yes! While LG uses it’s own method to obtain the video stream, it implements a spice client for keyboard & mouse input.
