Re: Raspberry Pi 4 + 7" Official Touch screen = Xorg High CPU Load

I found in Raspi-Config that you can disable the OpenGL driver and use the legacy one. Now all is working again. Will this driver stay part of Raspbian as the OpenGL one is buggy it seems.

Re: Raspberry Pi 4 + 7" Official Touch screen = Xorg High CPU Load

Sorry I had to go buy an HDMI cable to test that. So it does the same on the HDMI side also. So this is not a screen issue. Should I open a new issue on the Pi side? http://jdphotography.co.za/files/pi/pihdmi.JPG You state it is because of the OpenGL driver. How do I fix this issue? Can I put it bac...

Raspberry Pi 4 + 7" Official Touch screen = Xorg High CPU Load

Hi all. I have developed a system that uses the 7" Touch screen. It has been running fine on the Pi 3 using the screen for 2 years. Here you can see the load when I go to the charting tab http://jdphotography.co.za/files/pi/pi3screenok.JPG I now got a Pi 4 to make sure all is working fine in the fut...

Re: Does the 7" Official screen work with the new 4B ?

OK nevermind. I got it working. The new screen I got has the ribbon cable printed the other way around. I connected it the same as all my other Pis but this one I need to connect the other way around. All is working now.

Does the 7" Official screen work with the new 4B ?

Hi.

I got 2 new 4B pies and connected the 7" screen. When I power it up nothing happens. The screen stays black. Does the new Pi work with the 7" screen ?

Re: wlan0 gets de-associate after ap reboot

When you say my set-up should not work why do you say that? Can I not have 2 wifi connections on the same network on different IPs ? I have it that way on all my PI's. Why should it not work ?

Re: wlan0 gets de-associate after ap reboot

I want to have a bond but when I started the project I was told I could not bond 2 wifi connections. The reason for 2 is just in case the one fails then I still have another. They both connect to the same AP but each on a separate IP. If I could have one IP on both WiFi connections that would be fir...

Re: wlan0 gets de-associate after ap reboot

Are you using wpa_supplicant? Do you see wpa_supplicant processes running? There should be one process running by interface. Depending on your network setup: "ifconfig up/down" is equivalent to "ip link up/down". This is different from "ifup/ifdown" which go through /etc/network/* and launch variou...

wlan0 gets de-associate after ap reboot

Hi all. I have been running a number of Pi's in the field over the last 3 years. I have picked up some issues with the WiFi. Wifi will work 100%. All my PI's run on UPS power. Then if there is a power failure the AP will go down as that is not on back-up power. When the power comes back sometimes on...

Re: Warrenty of the Pi ?

The Zero is so cheap. Who is going to fuss over warranty replacement? Well some people dont even want to pay 2 cents to fit the header at the factory it seems. What I take away from all this is dont solder on any Raspberry Pi boards. Then you are ok. In future I will ask the supplier before we do a...

Re: Warrenty of the Pi ?

Bottom line is those connectors are not populated, and the pins are not included, so adding them is a modification. I really don't understand why you find this so hard to understand. The composite video output connector is not populated. Nor are the GPIO connectors on most Pi Zero and Pi Zero W. Do...

This is silly. One can't expect a vendor to warranty a device after you have attacked it with a soldering iron.

"Warranty void if modified" should be obvious enough to anyone.
Thanks for your input. It is noted.

He may have altered it by soldering the pins (which is part of the Pi design).
