Re: Rotate the touchscreen display? [SOLVED]

I know that this is an older post and it was solved for the original poster. However, I am still having issues with my touchscreen and I thought it would be a good idea to post my question here. What if the lcd_rotate=2 does not work? I have reviewed the config file line by line and cannot find any...

Re: 32:9 resolution 5120x1440 not working

Hi, I checked that setting, the 3 blocks mode is enabled. Moreover, that setting is only meant to be used for HDMI 1.4 due to its reduced bandwidth, however, the RPi uses HDMI 2.0 So how can that problem be solved now? In Windows it is working without any issues, so why can't Raspbian display that ...

Re: The system is halt when a face compare application is running.

If the Pi gets to 100deg it's broken - there is no way that can happen except a HW fault. Just replace it, will be the cheapest option.

Re: Text not being displayed in headers

Is that image of the background accurate - it seems to have lost a lot of colour depth, which might be the cause. Looks like a 16 colour display rather that the default. Have you made any changes that might have affected that?

Re: USB 3.0 hubs unreliable on Pi4

I do not (yet) have a Pi4. On my Pi's (zero, 1B, 1B+ ,2B, 3B) its not a problem backfeeding power via the USB to my experience Provided your PSU this way in has enough umph, you can run the Pi off this power. Its best to use the dedicated OTG power port to avoid any sudden power loss if you need to...

This would consist of a Pi with a monitor, keyboard, mouse. W...

Re: Difference between "Raspbian Stretch with desktop" and "Raspbian Stretch with desktop and recommended software"

What is the difference between the raspbian os and the raspbian image. Am confused The OS is the thing that runs on the Raspberry Pi (A bit like WIndows). The image is the binary file that contains all the OS that you put on the SD card to make it all work - it's a raw file, see https://en.wikipedi...

You need to set the custom timings in config.txt so they are correctly passed on to the DRM system once the framebuffers start up.

Re: Raspberry Pi 4 ROM bootloader

Just to be really clear, the two bootloaders - the one baked in to the chip, and the second stage bootcode.bin are both closed, contain proprietary information, and will not be released as source. Also, it would be inadvisable to use the EEPROM for anything else than what it is currently used for as...

Re: Screen has green pixels and flashes

That does look like a cable issue, but since you have changed it that is ruled out. Could be a bad connector on the board or perhaps even the monitor. Can you try the other HDMI port on the Pi, and if possible another socket on the display?

Hmm. Its connected to the access point, but may not have a IP address (presuming you are using IPv4).

Output from dmesg when it fails might be useful - just the last 100 lines or so (dmesg | tail -100)

Because of the demand for the Pi4, the other models have struggled to get production time. There is no intention of taking the Zero off the market. Pi4 production can now be relaxed so other models should be restocked soon.
