Rpi & error creating SDL window

Papp

Hello everyone,

I'm new to the forum and a complete noob with Rpi.

Today I received my first Rpi4 and I wanted to transform it into a retro console.
So I read the official instructions, flashed my sd card, and put it in the rp4.
After displaying the retropie image, the system stops showing the following errors:
lv10: Error creating SDL window! Could not initialize EGL
lv10: Renderer failed to initialize!
lv10: Window failed to initialize!
Wi-Fi is currently blocked by rfkill.
Use rapi-config to set the country before use.

I've seen this error in many old posts 2016, and a recent one, which wasn't helpfull.

Can anyone please help me with this?

Thank you so much in advance

Are you sure you downloaded and flashed the Pi4 image and not the Pi3 one ?

Papp

Hi, thank you for the extremely quick reply!
The file I flashed is named 'retropie-buster-4.6-rpi4.img'

That's strange. Did you modify the config.txt configuration file on the boot partition ?

Papp

I added 5 lines at the very end of the files as I am using a 5-inch screen.
The end of the file now looks like this:

[all]
#dtoverlay=vc4-fkms-v3d
overscan_scale=1

max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
hdmi_drive=1

Are you sure you didn't disable anything else ? Please post the entire file's contents.

No need, I tried uncommenting the line dtoverlay=vc4-fkms-v3d and now it magically works.
It's weird as the manufacturer explicitly suggested to comment that line for rp4.

Thank you so much for your help! I really appreciate that

That disables the GPU drivers for the Pi4 and makes your system unusable for RetroPie. Next time you report an issue, please include all pertinent information, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.
