I have Xubuntu 22.04 on Lenovo Thinkpad X1 Carbon from 2014 and I use ibus for inputting in different languages. This all may or may not be relevant.
I have a rather strange problem that I've never encountered before on any version of Ubuntu. After I log in all my keyboard keys act normal and have the same values as expected, but after some time I notice that some of my keys are remapped to some strange values and cause strange events when I test them in xev. As an experiment, I called
xmodmap -pke > keymaps1.txtright after I log in, so that the file keymaps1.txt contain the "correct" keymaps, and then, after the remapping happened, I called
xmodmap -pke > keymaps2.txtI then compared the resulting files calling
diff keymaps1.txt keymaps2.txtThe full diff I saved at https://pastebin.com/t6u6Dcw3 but it suffices to say that a lot of keys get remapped to weird keycodes, in particular PrintSc gets remapped to my Up key, and a lot of keys get mapped to keycodes I don't even have on my Thinkpad X1 Carbon keyboard.

able to find what causes this remap. It does not appear to have anything to do with me calling setxkbmap or ibus engine with any parameters. Where should I look?
