Salut,

Re: Pi 3B+ - No video output after update

Hey,

it seems that other people reported the same issue ( like viewtopic.php?f=65&t=265100 ) but the only "solution" provided is to reinstall the system completely.

Reinstalling the whole system after an update is not a solution...

Re: Rpi4 Manually start Desktop

Well, since I've set Retropie to start on boot, startx command does launch retropie ( emulationstation )

Finally found the right command

sudo systemctl start lightdm

I know this was a stupid question, but the answer is not that obvious :roll:

Hi there, stupid question, but I'm stuck and I can't find the answer... First, I don't want to start the desktop by default.

Re: PI 4 4gb 4k playback on chromium youtube

Could it be possible to have an "official" reponse concerning this issue ?

I mean, just want to open youtube on a browser and watch a video. That's it. Is it possible ?
thanks,

Re: PI 4 4gb 4k playback on chromium youtube

Hi !

The Rpi4 can't handle 4k videos on Youtube. Can't even handle 1080p videos correctly in fullscreen... Barely ok in windowed mode.

It can play 720p video smoothly in fullscreen, that's it.

Re: PI4 USB Boot

You can do the old-school style hybrid SD-USB boot by placing /boot on an SD card and running the root filesystem from USB (that's what I'm currently doing). See this post for a quick tutorial on how to do it: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=243610&start=50#p1498774 Hi Hawai...
