[PROBLEM] Waveshare 7.9" DSI - 400x1280@60Hz

[AndromedaStrain]

There is a button on the back of the display.

no the back of DSI display have only a I2C pin selector control for touch capacity that can be chosed between I2C0 or I2C1 pin for fan, a connector for communication/power
and USB type C for power

Try rotate=90 in /boot/cmdline.txt instead of rotate-270

[AndromedaStrain]

Try rotate=90 in /boot/cmdline.txt instead of rotate-270

not well,... now I summarize the working on...

with con figuration reported in this post have these result
BOOT PHASE
PH1    
after starting startx
PH2    

with line "rotate=90 " in /boot/cmdline.txt instead of rotate-270....
 during BOOT the scroll is upsidedowon...
PH3    

instead after startx MoOde GUI was the same...( as before reported...)
PH2    

what is very strange ist that: the touch screen is oriented Right respect to the wide screen
(how it should be and how we would like it to be)..
because when I touch phisically on the right top of screen
the arrow gone to the "m" icone form menù MoOde GUI
...wen scroll vertically with finger the MoOdeGUI scroll in the same time.. (but orizontally in irection of long side ..)

related your suggestion I've open a tiket support some an a tecnician is managing this case ... but is a hard situation  because also there is a jet lag that complicate moreover the comunication

however I take your suggestion seriously, in the forum other people may have already solved the problem

but if any person have suggestions to solve the problem i will thank

mmm, 270 and 90 are the same thing, just upside-down...
I'd try 180 as well, this will supposedly turn 90-deg ccwise, which is what you want.

I've try this too but not work...
in bootPhase do the scroll lines from rh to lh as is
   
in MoOde GUI instead the inerface is that

so... the display can actually be rotated in any of the four directions, and the text orientation proves it.
It looks like moode assumes it to be thin and tall, rather than thin and wide...
Or the framebuffer can be configured the correct way (using the orientation parameter), while the reported viewport never changes to 1280 x 400, and always remains at 400 x 1280, indicating vertical orientation only...

video=DSI-1:400x1280e,rotate=270 console [...]

maybe setting the above to video=DSI-1:1280x400e,rotate=270 changes anything? Just wandering wild here, but seeing you always report the viewport being 400x1280 I begin thinking it may be defined somewhere...

Let me know, looks an interesting task...

[AndromedaStrain]

The rotate 0 or 180 option was meant for screens that are mounted upside down. Landscape oriented screens should not need any display rotation.

Here's a screen shot of 1280 x 400 in the sim. The screen should report a viewport size of 1279 x 399.



Run the command below to show the viewport size and then refresh the Browser.

Code:

# Show viewport size
moodeutl -q "update cfg_system set value='viewport' where param='pkgid_suffix'"

# Hide viewport size
moodeutl -q "update cfg_system set value='' where param='pkgid_suffix'"

but in this case thet fields can be modified and completed wit a value for 90 an 270 .. where can modify?

tnks Nutul 4 U'r support it's apprecited!
I've try also to write ...
video=DSI-1:1280x400e,rotate=270 console [...]
but result was a  black screen
with
video=DSI-1:1280x400e,rotate=0 console [...]
video=DSI-1:1280x400e,rotate=90 console [...]
video=DSI-1:1280x400e,rotate=180 console [...]
do as
ph1 and ph1 in my past post #13
.. .i've forced tho show of viewport... with  SSH command
moodeutl -q "update cfg_system set value='viewport' where param='pkgid_suffix'"

and for all the viewport (0, 90, 180) the popup showed 400x1280
that's as appear as is the MoOde system force these viewport .....
