Please elaborate on what you mean by "unmountable display".
No comments on the patch itself, I just haven't heard that before.
Sorry, that word doesn't exist; maybe "mountable". I think "detachable"
is the correct word. The notebook's display can be removed from the
keyboard to act like a tablet.
Best regards

is installed in landscape orientation, but the display mode is in
portrait orientation. By default, the display output is rotated to
the left by 90°.
The sysfb quirk breaks the display by swapping display width and
height; and thus mixing up the display geometry. Fix this by keeping
the display as-is. The sysfb DRM drivers, usually efidrm, will pick
the correct panel orientation for the display.
Tested on a Lenovo D330-10IGM IdeaPad.
