The imager does a Verify stage to make sure it is a successful image.Īfter it was complete, I put the card in my Pi, and booted the image. I wanted 20.04 LTS, so I downloaded the 20.04 Server image through the imager.
But I am connected to a TV via lsb_release -aīurned image via the "Raspberry Pi Imager", straight from Ubuntu, via the tutorials page. In fact I'm posting from it right now, on Ubuntu 20.04 and running Ubuntu Desktop. # uncomment to remove color and display in monochrome # 2= Normal PAL, 18= Progressive scan PAL # Uncomment to turn the composite video port on Okay, this one is changed to turn your DSI display port on and be able to use composite video. While you are at it, remove that kernel boot option from the Grub default ( where I had you do previously), as it gets those settings from this file instead. There's also a lot of commented graphics options to play with if the changes needs more tweaking. # Note that this loads a "psuedo" KMS framebuffer that is better on Pi for desktop usage. # uncomment to increase signal to HDMI, if you have interference, blanking, or # uncomment to force a specific HDMI mode (this will force VGA) # uncomment if hdmi display is not detected and composite is being output By default it will be display's size minus # goes off screen, and negative if there is too much border # uncomment the following to adjust overscan. # uncomment if you get no picture on HDMI for a default "safe" mode # Enable DRM VC4 V3D driver on top of the dispmanx display stack # Some settings may impact device functionality. # on the IO board (assuming your CM4 is plugged into such a board) # If you have a CM4, uncomment the following line to enable the USB2 outputs # which forces the HDMI output into HDMI mode instead of DVI (which doesn't # If you have issues with audio, you may try uncommenting the following line # Comment out the following line if the edges of the desktop appear outside # Be warned that there *may* be incompatibilities with the "full" KMS overlay
# Uncomment the following to enable the Raspberry Pi camera module firmware. The full KMS overlay is required for X11 application support under # Enable the KMS ("full" KMS) graphics overlay, and allocate 128Mb to the GPU
# Enable the audio output, I2C and SPI interfaces on the GPIO header
There's only a config.txt under the firmware folder, not in /boot
