Public bug reported:
Steps to reproduce: - add custom hwdb rules for remapping keys (see the attach of my `cat /etc/udev/hwdb.d/61-ThinkPad-X240-keyboard.hwdb" for example) - run: $ sudo udevadm hwdb --update && sudo udevadm control --reload-rules && sudo udevadm trigger - and reboot PC to make sure that changes have took place What should happen: - changes should take place at TTY and in GUI session as well What happens: - changes take place in TTY session only while in GUI session something overrides these udev-based hwdb rules ---- Now, a little bit more details. Here is my /etc/udev/hwdb.d/61-ThinkPad-X240-keyboard.hwdb: ``` # ThinkPad X240: # - switch End and Insert keys (so that when Fn-Lock is enabled, End works without Fn). # - switch Home/End <> PgUp/PgDn evdev:atkbd:dmi:bvn*:bvr*:bd*:svnLENOVO:pn*:pvrThinkPadX240:* KEYBOARD_KEY_c7=pageup KEYBOARD_KEY_cf=insert KEYBOARD_KEY_c9=home KEYBOARD_KEY_d1=end KEYBOARD_KEY_d2=pagedown # http://fliplinux.com/udev-hwdb-numlock-0.html ``` TL;DR: it did work recently, but after packages' update it did stop to work in X session (but in TTY session it still works according to custom configuration). I'm ready to provide any other detailed information. I use Ubuntu MATE 18.04 with the latest updates. It took a lot of time for me to make that keyboard configuration work properly because without that text processing (such as coding) is unbearable. And it was really great when I did manage to make it finally work by turning a few contradictory HOWTOs and advises from here and there into working solution. Until the recent packages' update. The most interesting part is that `evtest' shows logs according to hwdb settings while `xev' doesn't. So I have my hwdb configuration working at any TTY but not during X session. I tried even to downgrade a few packages manually such as udev and systemd (because they have been updated as well) but it didn't make it to work again. $ sudo evtest /dev/input/by-path/platform-i8042-serio-0-event-kbd ===> [pressing PgUp above LeftArrow] Event: time 1576021876.063189, -------------- SYN_REPORT ------------ ^[[5~Event: time 1576021876.524882, type 4 (EV_MSC), code 4 (MSC_SCAN), value c9 Event: time 1576021876.524882, type 1 (EV_KEY), code 102 (KEY_HOME), value 1 Event: time 1576021876.524882, -------------- SYN_REPORT ------------ Event: time 1576021876.587770, type 4 (EV_MSC), code 4 (MSC_SCAN), value c9 Event: time 1576021876.587770, type 1 (EV_KEY), code 102 (KEY_HOME), value 0 Event: time 1576021876.587770, -------------- SYN_REPORT ------------ ^[[5~Event: time 1576021876.857851, type 4 (EV_MSC), code 4 (MSC_SCAN), value c9 Event: time 1576021876.857851, type 1 (EV_KEY), code 102 (KEY_HOME), value 1 Event: time 1576021876.857851, -------------- SYN_REPORT ------------ Event: time 1576021876.920816, type 4 (EV_MSC), code 4 (MSC_SCAN), value c9 Event: time 1576021876.920816, type 1 (EV_KEY), code 102 (KEY_HOME), value 0 Event: time 1576021876.920816, -------------- SYN_REPORT ------------ # Yes, it's registrating KEY_HOME as it should ===> [pressing PgDn above RightArrow] Event: time 1576021931.761434, -------------- SYN_REPORT ------------ ^[[6~Event: time 1576021931.880086, type 4 (EV_MSC), code 4 (MSC_SCAN), value d1 Event: time 1576021931.880086, type 1 (EV_KEY), code 107 (KEY_END), value 1 Event: time 1576021931.880086, -------------- SYN_REPORT ------------ Event: time 1576021931.926910, type 4 (EV_MSC), code 4 (MSC_SCAN), value d1 Event: time 1576021931.926910, type 1 (EV_KEY), code 107 (KEY_END), value 0 Event: time 1576021931.926910, -------------- SYN_REPORT ------------ ^[[6~Event: time 1576021932.037671, type 4 (EV_MSC), code 4 (MSC_SCAN), value d1 Event: time 1576021932.037671, type 1 (EV_KEY), code 107 (KEY_END), value 1 Event: time 1576021932.037671, -------------- SYN_REPORT ------------ Event: time 1576021932.092536, type 4 (EV_MSC), code 4 (MSC_SCAN), value d1 Event: time 1576021932.092536, type 1 (EV_KEY), code 107 (KEY_END), value 0 Event: time 1576021932.092536, -------------- SYN_REPORT ------------ # It works for PgDn as well!

Plus, unlike udev/hwdb it wouldn't be system-wide. Plus, udev/hwdb solution did work perfectly for me. Until something didn't break it. I'm eager to provide any information that developers may need. Just let me know what else do you need to know to help me to fix that broken behavior. Thanks in advance.
