Re: How to change splash screen logo on buster is???

Try this:

Code: Select all

/usr/share/plymouth/themes/pix/splash.png
But don't be supersized if it gets overwritten in a future update.

The RPi 4 has composite disabled by default. Use sudo raspi-config to enable composite mode. (Advanced menu A9 --> V2)

Re: Raspbian - USB drive not showing up under Eject menu in top right

You can drag & drop any folder from file-manager to the desktop.

Normally one would not fstab a drive that was intended to be used as removable media (hot swap)... Just let the automount feature do its job.

Re: one more time: disable screen saver

The problem is that, if you have a local autostart, it overrides the global one. So you have to either execute the global one explicitly inside the local one, or copy everything from the global autostart to the local one. This leave an easy alternative... Install xscreensaveer and set it to never a...

Re: one more time: disable screen saver

The xset commands require GUI desktop to be fully loaded so they won't work from rc.local.
Normally the commands should be put in autostart (default Raspbian install).
Do the xset commands work from the command line?

Code: Select all

xset s off
xset -dpms
The noblank command is not needed.

To check status:

Re: No USB auto-mount when running headless.

Use sudo raspi-config to set a forced screen resolution. (Choose anything other than monitor default). The reason is that by default (RPi4), if no screen is connected at boot then a display device is not created. Without a display device the GUI desktop does not start so any program that requires GU...

Re: Relay not sending power

In addition to what was said in the above replies..... The relay board in your link is a Solid State Relay (SSR) and can only be used with AC circuits and will not work with a DC circuit. You need to find a SSR that is specified to switch DC voltages or use a mechanical relay board.

Did you do an OS upgrade in the past rather than a fresh install?
The size of /boot is now ~250 MB.
I believe you must do a fresh install to get the larger size.

How did you install the OS?
Normally the image is automatically expanded to fill the card on first boot.
Looks like that did not happen.
Try the expand filesystem option in sudo raspi-config
