here: https://paste.armbian.com/oyozunowab (running through docker on fedora 42 latest everything after a restart, the same issue happens on a fresh download too) i dont have it available atm, i will include it as soon as i can get access to it, but last time i checked dmesg there was pretty much no errors no, not really, i changed the pins for D/C and reset iirc

ok so, i tried to replicate the issues i had but they just... didnt happen? everything just... works perfectly fine????? i have no idea if it was just that i was particularly unlucky or something, but i just compiled a working image fairly easily. edit: nevermind, when i retried after a restart i got a Failed to update binfmts [ update-binfmts --enable qemu-arm ] error, googling yielded almost no information (host: fedora 42) i did! its a russian store, so it probably has a bunch of countries region blocked (for me it works, even through VPN)

oh so THAT'S why Xfce didnt launch, good to know. i did try lowering the SPI frequency but the result is pretty much the same. i am using the panel-mipi-dbi-spi driver, i will check the script later and see how it actually works. i am 100% sure the display is not defective, it works perfectly fine through tft_eSPI on an esp32, i will try getting an another unit and see if it changes anything.

thanks! direct wiring has definitely changed something, i guess ill keep changing stuff and update if i get something upd: the direct wiring has definitely made an improvement, but it still looks offset, i have no idea how to fix this, changing stuff in panel-timing just.. does stuff randomly, and i have no idea how to pick the right one. does anyone know the solution to this kind of weirdness? this is the best i could get it:

hello again, i searched around and pretty much everything links back to this thread. this is the best result i could get on latest armbian, does anyone know what i can change? i think the problem is that the image is kinda shifted down and then goes back up? im pretty sure i need to change some kind of offset, but other than that im stumped

its an ili9488 3.5" cheap red SPI display, pretty much right after posting the comment i got it to output a garbled image, i did change the pins to match my pin connections. i was running orange pi branded debian, doing stuff on armbian doesn't work for some reason, im going to try to compile it myself. i completely removed touch from the DTS because i dont really need it. i am on orange pi zero 2w btw. for some reason i cant upload an image
