Acer TravelMate B3 screen rotated

[Hadmut Danisch]

Hi,
I just installed 20.04.1 on a brand new Acer TravelMate B3.

- First I tried Lubuntu 20.04.0 from a USB stick without problems, X11 working correctly. I did not install it because it was a 20.04.0

- Then I put a reguluar Ubuntu Desktop 20.04.1 on a USB stick and bootet from it. Even the console text output is normal for some time and then is rotated by 90 degree to the left.

The X11 (installation) screen then comes up completely rotated counterclockwise bei 90 degree. I then need to do a xrand --output eDP-1 --rotate normal to get things straight. Works normal then.

After installation it came up rotated again, even the login screen is rotated 90°

But sorry, can't help in debugging. If I don't find a permanent solution, I need to install Lubuntu or Xubuntu, because I need to get this notebook up and running by tomorrow.

I think I've found the reason, but not the solution.

I've put a
Section "Monitor"
Identifier "eDP-1"
Option "Rotate" "normal"
EndSection

into /etc/X11/xorg.conf, which did not help.

but then I noticed that this notebook comes with a flippable screen made for Win10 to be used as a tablet. When rotating the Screen, Xorg keeps turning the screen, but always wrong.

So Xorg is technically able to handle the changing screen orientiation when turning the notebook upside down, but it always chooses wrong rotation settings. Translation of screen oriention into xrandr settings is wrong.

ugly workaround:

systemctl disable iio-sensor-proxy

I still did not figure out, which component translates the accelerometer readings into screen rotations.

[Hadmut Danisch (hadmut)]

it takes a
systemctl mask iio-sensor-proxy
to make it permanently

[Daniel van Vugt (vanvugt)]

The system menu (top right of the screen) also allows you to lock the screen rotation.
