I appologize in advance if this is more of a kernel question than XWin question...
This is my keyboard: https://www.mercari.com/us/item/m42962366706/?gclsrc=aw.ds&&utm_source=google&utm_medium=cpc&utm_campaign=12877497088&utm_content=t0&adgroup=121903074456&network=g&device=c&merchant_id=126358573&product_id=m42962366706&product_id=294357559827&gclid=Cj0KCQiAy4eNBhCaARIsAFDVtI3ZkPN0rRWzmru6qKW_evp1Jpq4EGaW2RS_POoFnsZ2VHWJHkBhMmIaAqD9EALw_wcB Which is (more or less) the keyboard hp5185 here: http://v-sgsync-lnx1.nwu.ac.za/share.old/X11/xkb/symbols/inet So it seems my keyboard should be supported for all of it's consumer controls. Plus, on a previous install of Linux I had the keys working. Sorry, I didn't keep track of the version because I didn't realize it was going to be necessary. Yet now, on kernel version: uname -r 5.4.0-90-generic ...and Xorg -version 1.20.11 I run evtest against the Consumer Controls for my keyboard, for "/dev/input/event5"(in my case) I only get: KEY_HOMEPAGE KEY_SEARCH KEY_MAIL KEY_STOPCD KEY_PREVIOUSSONG KEY_PLAYPAUSE KEY_NEXTSONG KEY_VOLUME_UP KEY_VOLUME_DOWN KEY_MUTE I don't get: KEY_EJECT KEY_FINANCE KEY_SHOP KEY_SPORT etc...
