LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC


Any ideas?
How to change the resolution, orientation and make it sound?


It can be done as you see here
forum.linuxcnc.org/38-general-linuxcnc-q...ge-resolution#292499

Are you telling me that I need to start all settings again with a new image file?
Or there is a video driver, I can use for this image I already have? (Image from the LCNC downlods category)

Linuxcnc 2.9.2 for Raspberry Pi 4 & 5 images

Category: Installing LinuxCNC

Hello.
Sorry that I'm asking 2nd time, but...
How can I change the resolution, orientation (+touch) and make it sound?
I have a 10.1" IPS Touch display with resolution 1920x1200 @60 Hz + audio speakers.
But there is no sound, the resolution is only 1920x1080, no possibility to rotate the screen.
Is it possible to make it work?

On a Windows system the display works fine. (even tried on the Orange Pi PC with Armbian and it almost worked)

Nothing happening after reboot.
Checked the SD card on a PC the BOOT partition's config.txt file is changed, like I did it on the RPi5.

Any ideas?

A connection with a Windows tablet everything is working on the display.

LinuxCNC on Raspberry Pi 5

Category: Installing LinuxCNC

The BOOT is a different partition with the config.txt and i must to remove the card from the RPi5 and use a card reader. It is not comfortable to make and test the changes...
Before the file was created in the sytems boot folder

So, how can I open this config.txt on the RPi5?

You can edit the file whilst the system is running only thing is you'll have to open it as superuser....use sudo, if you don't know how to do that just google "sudo". It'll be easier as you'll find something you can understand.

Never, ever run
sudo rm -rf / as you'll destroy your system, just in case you see someone recommending doing this.

I'm always use sudo to edit files for network, autologin and else.

But this image for RPi5 i can't understand, how to set up. (no standart configs...)
Left HDMI audio, resolution and the orientation...
But I have no clue which tutorial to use...

should be in /boot/broadcom/
its just a txt so opening shouldn't be an issue, at least not for me and my installation on pi5
 

You are right. There is a config.txt file and it looks like the opened one on the PC via card reader.
I will try it.
Thanks.

Raspberry Pi doesn't use grub
Resolution is a issue with this image
You may have to enable sound see
www.raspberrypi.com/documentation/computers/config_txt.html
 

Is it possible to solve the resolution issue with the rotation?
I have tried the config.txt, but without success... what did i wrong?

You can try with the image for Pi5 (Lcnc292_pi5.img) that you find at this link:
