Google's Chrome OS "Wilco" Driver Working Towards Mainline Linux

Filed under
Linux
Google

For years now Google has been designing their own embedded controller (EC) for use within Chromebooks / Chrome OS devices.

But after about five years of the "ChromeOS EC" (cros_ec), there is a new embedded controller they have been working on. Coming soon to the mainline Linux tree will be the kernel support for a new ChromeOS "Wilco" Embedded Controller.

Wilco is Google's new embedded controller wired up over an eSPI bus. The new driver doesn't yield much to get excited about, however, but great that Google continues working on their own ECs and they are backed by open-source firmware and first-rate Linux support given their Chrome OS usage.

  • PulseAudio Plugin Allows For Better Bluetooth Audio Quality On Linux

    Right now on most Linux distributions when using higher-end Bluetooth headphones, the low-end SBC audio codec ends up being utilized by default which is subpar for the potential audio quality of the more expensive headphones. Fortunately, there are PulseAudio modules that allow for the higher-end codecs to be used.

    The low-complexity sub-band codec "SBC" is what ends up being used by default as it's native to Bluetooth and not proprietary or encumbered by patents. But newer headphones on the premium end of the spectrum also support LDAC, AptX-HD, and others with higher bit-rates yielding better audio quality.

Gustavo Silva: Disco Dingo Thoughts

Those already around me know I love Linux and my favourite linux distribuition is Ubuntu. One of the reasons Ubuntu is my favourite is how simple and compatible it is with pretty much all devices I have tried installing. Except my laptop, but that’s due to the graphics card. But hey, I fondly received the news that now we can select the option to automatically set nomodeset and other convenient tools when running the setup. For me, this means a major win. I previously had to set nomodeset manually and after installation I had to immediately modifiy some options in the grub’s defaults (namely set the acpi=force) but now, with this new option, the installation process which was already smooth, become (melted) butter. Thank you, honestly, person who remembered to include this option. This seems like a feature that will stick to Ubuntu 20.04, so I’m happy to now a LTS version will become even simpler to install too, so that’s great. The UI and custom-Gnome experience has been improved as well, in this custom flavour of Gnome. We now have a few more options for customization, including dark options of the themes but I am definitely pleased to say that the Gnome shell, in Ubuntu 19.04, really looks great. Read more

5 of the Best Linux Desktops for Touchscreen Monitors in 2019

The concept of using Linux on a touchscreen monitor or two-in-one computer has come a long way. Touchscreen support is now built into the Linux kernel, so theoretically any Linux distribution should run with a touchscreen. That said, not every distribution will be easy to use on a touchscreen, and this comes down to the desktop. For example, using a tiling window manager like Awesome or i3 isn’t going to do you much good on a touchscreen. Choose the right desktop (more precisely, desktop environment), and you’ll have a much better time using Linux with a touchscreen. Read more
