Re: max_usb_current on Pi 4

..... Well, if screw terminals add too much cost,.... It is not just cost. They take up a lot of precious board space. In addition, the RPi PCB are I believe 6 layer boards. Since the terminals are through hole components, the copper traces on 5 of the 6 layers must be routed around the solder post...

Re: Disable RealVNC VNC Conntect

What you are asking makes no sense. You are absolutely right in that I forgot to point out: No, I do not actually want to disable VNC (I'd know how to do that). I just do not want that VNC Connect app not to start. It autostarts after each reboot when I log in via VNC. I can quit it, and the VNC co...

Re: Disable RealVNC VNC Conntect

Hi all, I am desperately looking for a way to deactivate the autostart of the RealVNC VNC Connect app which starts up each time a user remotely logs in via a VNC connection. I see no need in this app to be active all the time and it bothers me a lot that I have to close it after each reboot and sub...

Re: Two Raspberry Pi, one monitor

So, if I get a second Pi and one new monitor, can I run both Pi off the same new monitor without having to p...

Re: How to turn off HDMI on blank screen?

It is much simpler to use the xset commands. On the RPi4 the HDMI will be turned off. (There is no blanking mode anymore only HDMI off). The monitor will then use its own timeout settings. In my case, on screen blank timeout, the monitor will show a no input banner for about 20 min. Then will shut d...

Re: How to add commands to LXDE autostart

autostart processes each line independently at near the same time in a parallel fashion. Or it does not wait for the command on one line to finish before starting the next command on the next line.
