I am see Example and Excute but that messaging "RPI4 not Support"
We aren't mind readers !

You need to tell us much more info about what you are trying to do.
Where is the example you are using ?

Another dangerous item from MagPi

Your tweet of a Pi with a relay board with exposed mains connections is really irresponsible. Do you not have anyone on your editorial staff that has a clue about Health and (Electrical) Safety ? :(

Re: Dual HDMI Output on RPi 4

That doesn't sound right. It should work twin headed "out of the box".

What exactly did you change in config.txt ?

Why the new forum account?
Because the old one had been given a holiday from the forums and "pro" thought they could sneak past the rule by creating a new account?

Re: Raspberry Pi 4 temperature

I switched tactics. I stopped, and then disabled the service that controls the fan. Now it just runs continuously when the Pi is on. My temps are now around ~40c with moderate use. Half what I was getting with just the heat sink. And more constant with no swings up and down. :D But only a 3% change...

Re: RPi 4 2GB - Cant set gpu mem above 600 / black screen

## gpu_mem GPU memory in megabytes, sets the memory split between the CPU and GPU; the CPU gets the remaining memory. The minimum value is `16`; the maximum value is `192`, `448`, or `944`, depending on whether you are using a 256MB, 512MB, or 1024MB Pi. The default value is `64`. For the Raspberry...

I was using ps and it was't there. So I enabled it and then it was there so I know I was looking in the right place :-) Having it running made no difference to the cursor issue (or to black corners around the tool tip popups). If I can find a spare SD card I'll do a fresh install and see what happen...

Can't think of anything else that may be different. But those black pixels around your tooltips make it look like an older version of xcompmgr is running.

I'm running with FKMS enabled and no compositing manager running, if that helps at all.
It would be helpful if you could explain how exactly you achieve that configuration. For those of us who aren't working with this stuff every day the acronym soup is hard to deal with.

Re: Raspberry Pi 4 Thread - general discussion

You can remove the 'untested' component and downgrade the relevant packages. If it causes other problems it would be good to know because it's likely to hit the main repo soonish. Sadly it's made no difference as you can see ... The cursor should be showing over one of the two "Continue" buttons. S...

Re: picfan - A PWM cooling fan controller written in C

Hi Peter, at the moment I'm using a cheap 30mm "Pifan" it is doing the job nicely of keeping a Pi4 cool. One reason why I didn't use the gpio-fan overlay is because it didn't seem to handle GPIO. I probably can still improve the control, as it is challenging to respond quickly enough, but not overr...

I wonder if he has the same issues with the Intel/AMD CPUs in every Desktop PC ? Or is it a case of "out of sight , out of mind " ?
