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.

Same result with gimp and scrot.

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...

I'm not sure if this is Pi4 or Raspbian Buster specific but I don't have a Pi3 set up right now...

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...

A couple of questions.... What type of fans have you tried this with ? Did you use any external circuit to control the fan ? I'm currently using a fan-shim and controlling it with the kernel device configured with "dtoverlay=gpio-fan,gpiopin=18,temp=65000" ISTR the Pimoroni guys saying their fan doe...

The 3B+ with overclocking runs easily at 1,5Ghz, same speed as the 4B stock.
And about half the performance :roll:

Whenever you have an application that when you load it you get a "Splash screen" that stays too much,
it means that this application got ruined.
(that's my opinion)
What a strange criteria to use as a basis for your choice of software.

The version in the Raspbian repo is indeed still 1.0.5 which qualifies as ancient compared with the current version 1.8.9

Re: Raspberry Pi 4B, tvhat & fan shim?

Some people have found that adding heat sinks can make things worse because it reduces the air flow over the heat spreader.
Also it depends on the thermal qualities of the pads.

I have a fan shim on the way. I should have it next week some time to test out.
I have found that a fan-shim (without a heat sink) on Pi4B4 in a coupe case will reach ~62°C when running four cores flat out with a stress test.

optocouplers work at the speed of light, they should not really introduce perceptible delays, but it way depend on the model of isolator used.

Pads are sticky and can be used to secure a heatsink to a device.

I doubt a pad would stick if one (or both) surfaces had paste applied but I've not got any pads here to waste trying it out.
