Cannot rotate display on new MM 2.4.0
-
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.

Thanks MichMich. That’s useful info.

@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?
