Hi,
Is there a known 'out of the box' working graphics server that comes with the buster image and LCD output ?
I have tried to install both xserver and weston but none works.
In the case of xserver, it complains that sun4i-drm_dri.so is missing.

gbm: failed to open any driver (search paths /usr/lib/aarch64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri)
gbm: Last dlopen error: /usr/lib/dri/sun4i-drm_dri.so: cannot open shared object file: No such file or directory

Where can I either find:
- the missing .so file
- a working configuration ?

Thanks !

We haven't tested it ourselves, maybe a user or customer would know more. We release the buster images as server images.

For the graphics, you might want to test the bionic images, which were meant to be desktop image and have graphics enabled by default:

Thanks, this works indeed.
I am using the 10' LCD. It is worth to notice that the whole display is offset to the right by about 8 pixels (and the missing 8 pixel column is displayed at the left)

Hmm, can you upload two pictures of the problem: a picture that shows the problem and a picture of the bottom of the LCD (so we can see what is the hardware revision of the LCD and more)?

Share the link of the location where you uploaded them. I usually use imgur but anything is fine.

Here is the back of the LCD:

And the offset glitch:

If that helps; a number at the bottom at the touch sensor:

Hi, did someone reproduce the screen offset that I have,
and that is shown on my posted pictures ?
Thanks
