Rotating Display again..

N6NG

Here I am again… Second MM and it’s somehow different from my first…
Loaded up following Sam’s instructions which worked perfectly.
I’ve got my MM working… However… I’m trying to rotate the screen.
Last time I made a MM I modified the boot/config.txt file and inserted a Display_Rotate=1 and it worked perfectly… this time I try that and it doesn’t change a thing… I tried several of the other ways mentioned in the forum that said would rotated the display and none of them worked. I’m using HDMI 1 on two different screens… One is a Samsung smart TV and the other is an ASUS computer monitor. No matter what I do, I can not get the screen to rotate. The config.txt file does list “display_auto_detect=1” but that is for DSI displays. Any suggestions? Thanks all…

@n6ng Sounds like you have a raspberry pi 4.

With those, there is a screen configuration app in the desktop menu, under settings. You’ll need to rotate the screen there, and deal with the CLI interface being wrong way.

For Raspberry 4 as of Nov 2020:

Click Raspberry Logo in the top left corner (open application menu)
Select “Preferences” -> “Screen Configuration”. A new window “Screen Layout Editor” will be opened.
In the new window menu, select “Configure” -> “Screen” -> “HDMI-1” -> Orientation

@bkeyport Nope… I’m using a Raspberry Pi 3B+
I will try what you suggested and see if it works for the Pi 3…
Thanks

@n6ng you did do

display_rotate=

right all lower case

N6NG

@sdetweil No Sam… I did display_rotate=1 and that didn’t do anything… I just tried the display_rotate=right and rebooted and that didn’t rotate the screen either…

@n6ng I guess what I need to do is see a config.txt that actually works and I can see what is different from the one I’m using. If someone could post it here so I can see it. I can do the comparison. Thanks again… especially to Sam whose script to install the magicmirror worked flawlessly… Great aid in getting it up and running.

@n6ng are you using bullseye?

cat /etc/os-release

PRETTY_NAME="Raspbian GNU/Linux 11 (bullseye)"
NAME="Raspbian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

If so, there appears to be a bug with legacy rotation. sudo apt-get update && sudo apt-get upgrade and try again.

They’ve done all sorts of major switching around with the new OS.

N6NG

@bkeyport I am running bullseye and I did the update and upgrade as suggested and a reboot but it didn’t change the rotation… I did the display_rotate=right and them rebooted… Still horizontal display after being rebooted…
Thanks for the suggestion though … at least I know I’m up to date…

@n6ng

I do believe the command is still numeric.

N6NG

@bkeyport Well I tried both ways display_rotate=right and display_rotate=1. Neither caused the screen to rotate… that’s what makes me think I’m missing something else… Don’t have the foggiest idea what it might be…

@n6ng Last ditch for Bullseye:

try each one of these.

display_hdmi_rotate=1
xrandr -output HDMI-1 -rotate right
lcd_rotate=1

If it don’t work, downloading stretch and starting over might be the only option.

sdetweil

@bkeyport not stretch… buster

BKeyport

@sdetweil Right. Buster. My mind is a version behind. 🤣

N6NG

@bkeyport Yes… I reloaded Buster and it works just fine… thanks all for the help… I was going to try Jessie but couldn’t get it downloaded. The download kept failing right at the end of the download… So then I tried Buster. You guys are a godsend when we have problems… The question is who do the experts go to when the experts have problems they can’t figure out?? Hope you all have your experts you can rely on or maybe you don’t have problems you can’t figure out… All have a Merry Christmas and a great 2022…
