    Default Display rotation

    I have a tablet PC without position sensors and I would ask you if is it possible rotate the display? KRandRTray can't do it.

    If the KRandRTray (graphical front-end to xrandr) can't rotate your display, then I think not. It comes down to how xrandr-complient your graphics driver is (which you haven't mentioned). I'm assuming you're using a proprietary driver? Which version of openSUSE?

    Deano_ferrari I modified /etc/X11/xorg.conf.d/50-device.conf adding this option:
    Code:
      Option          "RandRRotation"      "on"
    and now I can choose which rotation use. But left and right rotation don't work, only 180 goes well...

    Great!!! Deano_ferrari, I observed that
    Code:
    xrandr -o left
    xrandr -o right
    commands WORK FINE!!!
    But instead KRandrRTray not, very strange...Moreover, coordinates of pen aren't inverted correctly, like mouse. What do you think about?

    The pen is using a differnt driver (like Wacom or evdev) so it will need to be rotated using commands like xinput set-prop or xsetwacom. You at this link at section 4 to see some examples on how to rotate an evdev/Wacom device.

    Thanks for your update MaxiPigna. I wasn't aware of that option for nvidia (although I don't have that hardware to check with anyway). It looks like you've neraly got it sorted though!

    If you still find KRandrR doesn't work, I would check/submit a bug report with kde.org

    KRandRTray seems to be broken since a long time (https://bugs.kde.org/show_bug.cgi?id=220085). That's why I always use the command line way.
