Hello!

I am currently trying to set up my Mimo Vue 10.1" Capacitive Touch Display, USB (UM-1080C-G) with my Raspberry Pi Zero 2 W running the latest Raspbian OS (2023-02-21) Debian Bullseye 32-bit.



I have followed the instructions on the page https://www.mimomonitors.com/pages/u...raspberry-pi-3 and have my Vue running just fine in both the 1280x800 resolution and with the touch working as well.

The only problem I am encountering is that I am unable to rotate/Orientate the screen 90 degree.

I have tried the following:

david@rpi:~ $ xrandr -o left
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  2 (RRSetScreenConfig)
  Serial number of failed request:  14
  Current serial number in output stream:  14

david@rpi:~ $ xrandr --output default --rotation left
xrandr: output default cannot use rotation "left" reflection "none"

david@rpi:~ $ xrandr --output default --rotate left
xrandr: output default cannot use rotation "left" reflection "none"

I have also tried editing the /boot/config.txt using the following inside the:

# Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d
max_framebuffers=2

Added:

 lcd_rotate=1

And also added:

display_rotate=1

And I also tried them both

 lcd_rotate=1
  display_rotate=1

And commenting out

dtoverlay=vc4-kms-v3d

Having commented out dtoverlay=vc4-kms-v3d cause no image on the LCD.
Having un-commented out dtoverlay=vc4-kms-v3d and using lcd_rotate=1 resulted in the same normal horizontal view.
Having un-commented out dtoverlay=vc4-kms-v3d and commenting out lcd_rotate=1 while using display_rotate=1 resulted in the same normal horizontal view.

It would be great if you have a solution for this!

Thanks!

David
