Surface Laptop 3 and Linux

I recently acquired a Microsoft Surface Laptop 3 and installed Fedora 36 on it. Everything works by default except touchscreen. For touchscreen support you need the surface-laptop kernel.

Tips

Keyboard + Mouse

I found that Fedora Beta was missing drivers for keyboard and touchpad on first boot so I had to use keyboard and mouse attached via USB port. After I ran an update to get latest available kernel and did a reboot, they worked fine.

I expect Fedora final won’t have this issue.

HiDPI Scaling

By default Gnome only permits scaling at 100% or 200%. With the 2256 x 1504 resolution screen, I wanted something closer to 150%. Fortunately, this can be achieved with an (experimental!) setting:

$ gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"

Once that’s set, you should see the option to scale to 150% appearing in the Gnome display settings (you may need to logout and login first).

Firefox

Be sure to install firefox-wayland for much smoother UI performance.

VA-API

Hardware accelerated encoding/decoding of audio/video codecs via iHD driver. Install RPM Fusion non-free repo and then install the intel-media-driver package:

$ sudo dnf install https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
$ sudo dnf install intel-media-driver
