            Bug ID: 94865
           Summary: RFE: Inverted axes hwdb quirk
           Product: Wayland
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libinput
          Assignee: wayland-bugs at lists.freedesktop.org
          Reporter: yaneti at declera.com

After a keyboard+trackpoint(packaged together) replacement (german -> english)
on a ThinkPad E145 the trackpoint directions flipped. The evdev InvertX InvertY
options in the old evdev X driver can be used to correct this. Maybe something
similar can be introduced in libinput

Quotes from the IRC chat with whot:
< whot> that is just weird. I wonder if the bios or fw usually accounts for it
< whot> yaneti: bentiss says there's nothing in the ps2 code that suggests
inversion is a normal thing
< yaneti> whot: oh well, thanks anyway. guess I'm shouldn't expect any
reappearance of InvertX/Y in the new stack..
< whot> not as config option, we may add it through the hwdb if there's a set
of devices that need it
< whot> come to think of it, there *is* a set of devices, otherwise we wouldn't
have the option in evdev..
< whot> yaneti: file a bug anyway so all this is archived
