Re: ubuntu 20.04 ubuntu-desktop dual hdmi output

Hi,
Try adding dtoverlay=vc4-fkms-v3d to /boot/firmware/usercfg.txt followed by a reboot.
After I applied this to my system both screens became active.

Re: Issues with the K400 keyboard

Please ignore my comments reference not needing to pair - I was not aware that if the keyboard was paired with another dongle it lost is pairing with the original but as a result of HawaiianPi's reply I decided to consult the Logitech guidance and now am much enlightened. Sorry if I caused confusion...

Re: Issues with the K400 keyboard

The power adapter that you are using should be O.K. as it is capable of supplying 2.5amps which meets the 3b+ spec. I have just set up my 3b+ to use the K400r keyboard (was on my rpi4) and it works without any problems using a 2.5amp supply. Do you have anything else plugged into the USB sockets? Ca...

Re: Issues with the K400 keyboard

I have 3 slightly different K400s - K400r, K400+ and K400 plus and all work on Pis models 0 to 4. None of those models use Bluetooth they are all USB wireless. All have worked out of the box after plugging in the dongle without any additional software on the Pis. I have never tried NOOBS I have alwa...

Re: Raspberry Pi Zero DOA?

My experience shows that, unlike other Pi models, if the SD card is not inserted and correctly seated there is no light on.
It's worth a check.

Re: Video Jukebox - Is it Possible?

How about a different approach. Utilise a PI Zero as the 'selection' system with a touch screen display. (or any other model - just zero is cheaper) Utilise a Pi (x) as the back end system driving the player software and using its HDMI output for the display. Use serial or ethernet connection to lin...

Re: WI-FI on RPi Zero

It is possible that you have not set a DNS Server address. In the example below I have used the Google servers but you can use those supplied by your ISP. Please note that I have used the Interface & wlan0 option but you could use the SSID, the entries for both are the same. You just need to replace...

Re: can't install fpc and lazarus on raspberypi

Was this on a B+ or the new Pi 2? I encountered the same problem on a B+ and the fix, I am happy to say, worked. However I tried the same fix on a Pi 2 and I could not get it to work (possibly finger trouble as I am new to Linux based systems) I then decided to upgrade to jessie and see if Fpc and L...

Re: LAZARUS 1.0.6 EASY INSTALL FOR RASPBIAN WHEEZY. Zog - I have just got round to using FPC/Lazarus.
