      Just updated to 2.4.0 without problems and followed these steps to enable OpenGL:

      https://github.com/michmich/magicmirror/wiki/configuring-the-raspberry-pi#enable-the-open-gl-driver-to-decrease-electrons-cpu-usage

      After that, my display is rotated, i.e. running in landscape mode. So I continued to follow these steps:

      nano ~/.config/lxsession/LXDE-pi/autostart
      @xrandr --output HDMI-1 --rotate right
      

      Display is still rotated though. I tried to manually run xrandr over SSH and got:

      warning: output HDMI-1 not found; ignoring
      

      Maybe I cannot run that over SSH? Any hints how to proceed?

        I updated my Mirror yesterday and used dtoverlay=vc4-fkms-v3d instead of dtoverlay=vc4-kms-v3d and didn’t have to change anything else to keep the screen in portrait mode.

          @madscientist Thanks! I’ll try when I get home. And the fake OpenGL drivers don’t push the CPU/temp too much?

            My RasPi seems to run at ~25% load according to the taskbar, when the Mirror runs in the background.
            Edit: Just checked the temps via command prompt and it’s at 63°C. I think that#s too high and will have a look at it tomorrow.
            More edit: Without MM running the temps are around 56°C. So the 63°C - although it seems high - are good enough values.
            I also tried the dtoverlay=vc4-kms-v3d but the screen rotation didn’t work at all and the screen resolution was very low and I couldn’t adjust it to FHD.

              @madscientist Switched to dtoverlay=vc4-fkms-v3d and everything seems to work fine. MM runs at a few % CPU so it looks very good, maybe even lower than with OpenGL, but I haven’t gone into details.

              What command do you use to check temperature?

                /opt/vc/bin/vcgencmd measure_temp

                  FYI, in a healthy state, my Pi runs at 66 degrees. With the misconfigured GL drivers, it reaches 85 degrees. So 63 is perfectly fine.

                      @michmich why does electron have to be updated?
                      With electron 2.0.0 my Pi runs at 75 degrees. (I have switched to “toverlay=vc4-fkms-v3d”.)
                      Now i have downgraded electron to version 1.4.15.
                      My pi runs now at 49 degrees and the MagicMirror Software is faster.

                      I use Raspberry Pi 3 with cooling fins!

                        @philreis i have the same problem - using toverlay=vc4-fkms-v3d i have 75° and a load above 1 the whole time.

                        How does electron downgraded work?
