Fixes

61-sensor

This udev rule fixes the wrongly rotated screen. Just save it as /lib/udev/hwdb.d/61-sensor-MiniBookX, make sure you have iio-sensor-proxy installed and with screen-autorotate installed and activated the screen rotates always correctly.

Grub menu too small:

Edit /etc/default/grub and change GRUB_GFXMODE to 1280x1024x32.

GRUB_GFXMODE=1280x1024x32

Then re-create the grub boot menu.

kernel boot messages rotated:

Edit /etc/default/grub and add fbcon=rotate:1 to GRUB_CMDLINE_LINUX.

GRUB_CMDLINE_LINUX="fbcon=rotate:1"

Then re-create the grub boot menu.

Workarounds

Touchpad freezes:

Unload the kernel module and load it again:

sudo modprobe -r i2c_hid_acpi
sudo modprobe i2c_hid_acpi

xrandr:

randr does not work and either does nothing or reports an error:

xrandr --output XWAYLAND0 --rotate normal
 X Error of failed request:  BadMatch (invalid parameter attributes)
   Major opcode of failed request:  140 (RANDR)
   Minor opcode of failed request:  7 (RRSetScreenSize)
   Serial number of failed request:  22
   Current serial number in output stream:  2

Using gnome-randr you can change the display from the command line

gnome-randr --output DSI-1 --rotate right
