    Phoronix: The Lenovo T450s Is Working Beautifully With Linux

    A couple weeks ago I bought the Lenovo T450s, this is my first laptop-upgrade in about three years and I have to say... I am so glad that I did upgrade. Over the last two weeks I've been using the T450s as my daily-driver and its been working almost perfectly under Fedora Linux.

    BIOS update and M2 SSD: careful!

    Pro Tip:

    If you have a M2 SSD in the laptop and you use it under Linux, then be _very_ _very_ careful when doing a BIOS update: the update will change/reset the setting for how the M2 SSD is used.
    A reboot after the update will wipe the M2 SSD!
    So immediately go into the BIOS settings on the first reboot after the update and fix the setting.

    (this happened on several occasions for me on my T440s)

      Thanks for the heads up fhuberts! I'm currently not using the 16gb m.2 SSD for anything, I was thinking of playing around with turning it into a cache-drive though.

        Sorry but what is written in the bad and ugly sections of the article contradicts the article title.

        Of course Lenovo doesn't give a fuck about linux and things not working are to be expected but that doesn't make it a beautiful experience.


        BTW michael could you do a power consumption test on browsers?

          The only benchmark that absolutely blew me away in the difference was compiling the linux kernel. I don't know if this was simply because of the difference in RAM (8gbs instead of 4) or because Broadwell is just that good for tasks like code compilation, but compiling the Linux kernel was consistently multiple times faster on my new system vs my old.
          Or something goes wrong during that benchmark , 30 sec for i5-5200U sounds impossibile as i7-5600U does it for 280 seconds

            The system IS working beautifully. The power applet is a KDE-specific bug, the screenshot utility is a KDE-specific bug (gnome-screenshot works fine), the webcam driver probably just needs to be updated since the t440s works fine, and I'm not docking Linux for the touchpad / trackpoint issues since PROPER support for them isn't until 4.0 and I am running 3.19. Even the power consumption, while not AS GOOD as windows is still more than enough for me using the system.

              My php is shit, so if someone who IS familiar with php wants to look over the linux-kernel-compile test and look for a possible bug, or if Michael feels like doing it, then that's up to them. All I know is that I ran the linux kernel compile test suite twice and both times it came out to be ~30secs

                Just reran it

                Test Results:
                30.589812040329
                27.141097068787
                27.059966087341
                27.058166027069
                27.104182004929
                27.083301067352

                Average: 27.67 Seconds


                Not saying you're wrong, dungeon, cause that is rather odd, but if the test is broken then its consistently broken. That wasn't a just 'one time' fluke.

                  My point is that integration and proper QA is what makes an experience beautiful. And linux doesn't have that. Specially when you install your own OS. And if you want a good laptop this is what you have to do.

                    Test profiles aren't even PHP. Here's what build-linux-kernel does: http://openbenchmarking.org/innhold/...12fe2931f0645f
