Tutorial: Colored emojis in Chromium

Microsoft has a color emoji font, Segoe UI. A nearly current version can be found here . But this is not a perfect solution. Segoe UI cannot display every single emoji in existence, so I use a combo of Segoe UI and Noto Color Emoji . And these commands will download, extract, and copy the two fonts ...

Re: Vdesktop: Ultimate Raspbian Virtual Machine Script. Feedback wanted!!

Good morning, everyone. Well my Pi 4 finally arrived, and after some extensive testing in several configurations, I am relieved to announce that using vdesktop, Raspbian Stretch runs at 100% native speed on a Pi 4. The vdesktop script has been updated a bit and a couple bugs worked out (see the gith...

Re: Google Maps is totally garbled/unusable on Pi 4!

Update: problem is solved!
It turns out FKMS was not the direct cause, but a trigger. I renamed ~/.config/chromium to something chromium wouldn't recognize and haven't seen the problem since.
Before renaming it, I made sure that no chrome flags were modified.

Have you done sudo apt update sudo apt upgrade. Google Maps is working fine for me on pi4 Yes, I am fully upgraded. This problem only occurs when the FKMS driver is on .

[SOLVED] Google Maps is totally garbled/unusable on Pi 4!

Pi 4 running unmodified Raspbian (except I made sure OpenGL is on), running Chromium.
Google Maps is unusable. This never occurred on my Pi 3.

Why is this happening, and is there any alternative than to disable GL via raspi-config?

Re: Low voltage warning even though gpio being powered with 5.07V?

Preferably 18AWG. Had some spare 18 AWG wire handy. So I soldered it to a breakaway female header, which sticks in the GPIO. Webcam-1568920235-min.png Lightning symbol disappeared! A large capacitor might clean it up a bit once you've fixed the wiring. Thought about it, but the power supply already...

Re: Low voltage warning even though gpio being powered with 5.07V?

Good idea measuring directly from the GPIO pins... 4.65V!
I understand voltage drop, but never would have thought such a short length of wire could have made a difference this bad.

Well I know better than to crank up the power supply. (fried a 3B doing that)

What wire thickness is necessary?

Low voltage warning even though gpio being powered with 5.07V?

outlet --> 5v 20A power supply --> Pi 4's gpio pin

Pi boots up, but lightning symbol is showing
Tested the power supply's output and it's giving a steady 5v. Adjusted it to 5.07V, and still, lightning bolt icon.

Here's my setup:

Chromium occasionally 'shifts' UI if GL is on - Pi 3 running Buster

If I enable OpenGL, occasionally Chromium will look like this until I move the mouse pointer near it.
