I didn’t see it in the preliminary report, but does it work when you boot another OS?

[Totof]

ello

I have the same issue with a CM4

Can you try this command line in a terminal ssh and give your output

export DISPLAY=:0

xrandr --listmonitors

Sudo startx

perhaps some information in it
I do the same after work, my waveshare was recognized but the résolution is bad
and no conf in /etc/xorg

[Totof]

Hello again
my output

My waveshare screen’s size is 1280x400 , it’s a 7"9 inch hdmi and touchscreen

[Totof]

Hello trendy

For me yes with opios or third party raspios but both use lightdm

With Dietpi and a littlebit further

Hello

Perhaps this link can help
HDMI can’t get mode for 1280x800 resolution

After a few days of test , in fact the Dietpi version works perfectly with my television screen and HDMI so it’s just a problem of resolution of screen
The link gived before don’t work for me !!!

@Totof

in fact the Dietpi version works perfectly

There is nothing Dietpi here.

[Totof]

@boxer

There is nothing Dietpi here

It’s exactly that !

Have you an idea how to solve this problem of custom resolution who is unrecognized ?
The 7"9 waveshare touchscreen was recognized by the orangepios with kernel 5.x
and also the raspios with same kernel

@Totof

Have you an idea how to solve this problem of custom resolution who is unrecognized ?

Better to use other hardware and other OS where this works.

@Totof

with same kernel

It is not the same.

[Totof]

I don’t think it’s a hardware problem
On my TV screen the HDMI output of the CM4 work perfectly
And I don’t think that the os it’s a problem too, many other os don’t work with the resolution of my 7" 9 screen with the CM4, except the official orangepi os and the thirdparty raspios for orangepi
It’s just a resolution problem
And the Dietpi os is perfect for what I need and want
