Waveshare 7.9" DSI Not working properly

[Wheaten]

if you mean the touch screen is not rotated look at:

[PLUGIN] Touch Display

it’s been fixed on kernel 6.6 you can download this file, rename it to “vc4-kms-dsi-waveshare-panel-fixed.dtbo” and place it on /boot/overlays then you can use this fixed overlay changing the declaration in userconfig.txt dtoverlay=vc4-kms-dsi-waveshare-panel-fixed,2_8_inch
