Stuck in boot sequence after LCD driver install

You followed the "online" instructions listed here?

Can you post the /boot/config.txt file ?

@quicksilver didnt work, unfortunately.. got to loading text and then went blank.. going to try the orig drivers and get the config file

The driver installer disabled the new GPU drivers by commenting out the vc4-fkms-v3d overlay.

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
#dtoverlay=vc4-fkms-v3d
#max_framebuffers=2

RetroPie will not work with this configuration on the Pi 4 - you should enable back the overlay and re-test.

That did the trick - thanks!

@mitu follow up question.. If I attempt to go to terminal via this LCD screen (hitting F4 while in EmulationStation), I get a very similar situation as my original screenshot.. poor resolution of the text screen and it looks like it's frozen.. I am actually able to type a command if I want, however I can't actually see what I'm typing since it's just a frozen screen

Try changing the framebuffer_width/framebuffer_height and enable the overscan_scale option. See if it makes a difference, though my suspicion is that the video rotation might be causing this.

@mitu Sorry it took me a bit to reply, have a 2month old and most of my "free time" is taken up with other stuff, lol... I just tried both of these options, both separately and together, and didn't seem to resolve it.. Where were you seeing the video rotation?

It'a parameter to the mhs35 overlay from the config.txt file you posted a previously:

dtoverlay=mhs35:rotate=90

@mitu derp, dunno how i missed it.. what's strange is that is the default settings after installing the drivers. The 90 will put it in a landscape view, so I guess this screen is portrait out of the box (before the installation of the driver).. anyway, if I remove the rotate, the screen won't work (white screen), and so at the moment I have it set to 270 so that way it's back to landscape with the pi power plug at the top.. I tried accessing terminal with it upside down (rotate=90) and it was still happening...

I think at this point I'll just hook it up to a monitor, get all the pi settings I want, and then just avoid needing to go to terminal when on the mini screen.. thanks for your help with this
