ThinkPad T530.
In X, it turned out the TrackPoint no longer moves the cursor, and the left&right "mouse" buttons that are between whitespace and touchpad no longer work. And the middle "mouse" button prints endless d.
So I press the middle "mouse" button, then I may hold it or release it, and it has an effect as if someone holds d key:

ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd

Pressing Shift during this has its effect:

ddddddddDDDDdddddddddddddddDDDDDDDDddddddddDDDDDDDDDDDDddddddDDDDDDDdddddDDDDDDDDDDDd

Pressing Ctrl as well - my editor pops-up a dialog: Delete this note? Yes No
Interrupt the d spree by pressing almost any key.
The genuine d doesn't print on the first try just after the middle "mouse" button d, it starts working from the second press.

On another occasion, the middle "mouse" button produces equal signs instead of d, after I've pressed no longer working left&right "mouse" buttons, but I can't figure out the exact sequence needed:

==============

xinput --list:

⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ /dev/wsmouse0                             id=7    [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ /dev/wskbd                                id=6    [slave  keyboard (3)]

The /dev/wsmouse is gone, it used to be there - I did TrackPoint scrolling by dragging with the middle button:

xinput set-prop "/dev/wsmouse" "WS Pointer Wheel Emulation" 1
xinput set-prop "/dev/wsmouse" "WS Pointer Wheel Emulation Button" 2
xinput set-prop "/dev/wsmouse" "WS Pointer Wheel Emulation Axes" 6 7 4 5

But now:

xinput --list-props /dev/wsmouse
unable to find device /dev/wsmouse

mouse.tp.swapsides=0
mouse.tp.disable=0
mouse.tp.edges=0.0,5.0,0.0,5.0
mouse1.type=ps2
mouse1.reverse_scrolling=0

where mouse is the touchpad; and the mouse1 is the trackpoint.

In tty, the TrackPoint and all 3 "mouse" buttons work as expected. But I recall I had had the pointer not working in tty, and I don't recall that I had enabled it as I feel no hurry to make it work.

Furthermore, startx doesn't work (I hadn't tried it before, this time is the first time).
rcctl enable xenodm && rcctl start xenodm does work. Dunno if this is relevant but it might be.
startx:

I am a rather novice "OpenBSD as a desktop" user, and I am in the process of making desktop-oriented config tweaks, which I've lost track of, since there is a freaking number of config tweaks needed for a usable desktop and I am still at the point of "major things work, comfortable things don't", or "80% done, have got to finish the remaining 80%" 🙂
By "'ve lost track of" I mean that I might have tweaked something, and it had worked back then when I tried it but broke after a reboot, and I might have forgotten that tweak. I try to be careful to not break things but who knows. The reboot was a forced one:
The laptop had been left in zzz state when power outage occured, and on the boot there were cleared messages about filesystem. Something important might have been wiped out?
