    Question Kali for Raspberry Pi 7inch Display

    Hello, just a quick question.

    How do i rotate the display 180 degrees on xfce desktop environment? My 7inch display is upside down with the power cable at the bottom making it cause to bend on my custom stand,

    I tried using xrandr command in terminal but it couldnt detect the offical 7inch display made by Raspberry Pi foundation.
    i also tried the display setting which doesnt show a dropdown menu.

    Thanks

    I have the same problem.

    But want to rotate not only the xfce display, I want to rotate the whole screen 180 degrees from the beginning of the booting. I want the terminal and the xfce rotated.

    Does the 7" display use fbtft ? If so you probably need to pass something like "rotate=180" when the module gets probed. This could be done similar to how we do with the rpi-tft image as seen here:

    https://github.com/offensive-securit...pi-tft.sh#L239

    Note that it's only a possible example, and you should NOT just copy and paste that line into such a file on your system. I don't have a 7" display for the rpi, so I don't know how it is set up.

    Just add the following line to your "/boot/config.txt":

    Code:
    # Rotate screen 180 for 7" touch screen
    lcd_rotate=2

    don't forget to mount /boot first via

    Code:
    mount /dev/mmcblk0p1 /boot
    Hope that helps,

    Great!
    It worked.
    Thank you.

    I did not mount /dev/mmcblk0p1 /boot.
    So I did not see the "right" boot folder with the right config.txt.
    Without the mounting there is a boot folder but with another config.txt and it seems to be the wrong config.txt. But after the mounting everything went the way I wanted to.


    Thank you.

    sorry to bring up a thread that is almost 4 months old but im still having the same issue with the rotated screen.. just built my Pi with 7" official display, the latest arm image from the kali website, i was able to do the basics with no issues (apt-get update, apt-get upgrade, apt-get install kali-linux-full and apt-get dist-upgrade) but when i try to do the fix posted by reason. i dont get a config.txt file .. has anything changed since this post was made with the kali image???

    Hi k13pt0,

    don't worry about not having a config.txt. Just create it.
    It'll work, trust me.
    Make sure you mount /boot first though.

    Have fun,

    Did you buy a display frame from Amazon? There have been defective cheap displays frames that've been circulating from there.

    Here's the link, check the reviews:

    They manufactured it wrong LOL
