Live For Speed, a online racing simulator, now can be installed in Ubuntu 16.04, Ubuntu 18.04, and higher easily via Snap package.

Live for Speed is a serious racing simulator. No arcade modes, no steering aids – YOU have to do the driving.

The forces affecting the car’s motion are simulated individually at each wheel. We recommend the use of a steering wheel, because although you can use the keyboard and/or mouse, a wheel and pedals provide a lot more accuracy. The force feedback sent to the steering wheel is calculated directly from the forces, with no canned effects. This allows you to feel what is happening at the contact patch between your tyres and the road, helping you to get closer to the limit without exceeding it too much!

Thanks to Taqi Raza, you can now install LFS in Ubuntu via Snap package, which is built against Wine platform.

To install the simulator in Ubuntu 18.04 and higher, simply search for liveforspeed in Ubuntu Software.

  1. first install wine-platform
  2. and then install live for speed.

For Ubuntu 16.04, open terminal (Ctrl+Alt+T) and run following commands one by one to install snapd, wine-platform, and liveforspeed

sudo apt install snapd

sudo snap install wine-platform

sudo snap install liveforspeed

Once installed, launch the software from application menu. For the first time, it sets up wine environments and installs the racing simulator automatically.

Linux Kernel 4.20 was released a few days ago. Linus Torvalds announced:

Let’s face it, last week wasn’t quite as quiet as I would have hoped for, but there really doesn’t seem to be any point to delay 4.20 because everybody is already taking a break.

And it’s not like there are any known issues, it’s just that the shortlog below is a bit longer than I would have wished for. Nothing screams “oh, that’s scary”, though.

And as part of the “everybody is already taking a break”, I can happily report that I already have quite a few early pull requests in my inbox. I encouraged people to get it over and done with, so that people can just relax over the year-end holidays. In fact, I probably won’t start pulling for a couple of days, but otherwise let’s just try to keep to the normal merge window schedule, even if most people hopefully won’t even be back until over the merge window is over.

As to the details of this last week of 4.20 – most of it is networking (drivers, core networking fixes, bpf). There’s a few other non-network driver updates too, and a revert series of some of the x86 inline asm changes that were obviated by upcoming compiler support.

… …

Changes in Linux 4.20 include:

  • AMD Picasso APU support as well as Raven 2 APU support
  • Intel DRM driver has full PPGTT support for Haswell/Ivy/Valley View hardware.
  • The open-source NVIDIA Nouveau driver has initial HDMI 2.0 support.
  • The NVIDIA Xavier “Tegra194” SoC has initial display support.
  • Support for the Hygon Dhyana CPUs
  • Intel 2.5G Ethernet support via the new “IGC” driver.
  • LG Gram laptop support
  • File systems improvements, drivers updates, and many other changes.

How to Install Linux Kernel 4.20 in Ubuntu:

For easy way, there are a few third party tools, e.g., UKTools and Ukuu, make it easy to install the latest Kernel in Ubuntu.

You can also manually download the .deb binary packages:

Depends on your OS type, download and install the packages in turns:

  1. linux-headers-4.20.0-xxxxxx_all.deb
  2. linux-headers-4.20.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  3. linux-modules-4.20.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb
  4. linux-image-xxx-4.20.0-xxx-generic(/lowlatency)_xxx_amd64(/i386).deb

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio), amd64 for 64bit system, i386 for 32bit system, or armhf, arm64, etc for other OS types.

Also you can download and install the kernel binaries via terminal commands (Ctrl+Alt+T):
