If I'm not mistaken Xorg is a setuid binary, so i can access devices under /dev/input without problems. when i was testing sway a while ago i attempted to use a devd ruleset to change thing so that the devices were in the "video" group and had appropriate permissions. if you are using the drm-kmod you'll already are a member of this group. i don't think i ever got the devd ruleset working to my satisfaction as i see a shell script that does this in my ~/bin/ directory that does this for me :) i also remember having issues with mouse and keyboard input using sway - these environment variables seemed important: export XKB_DEFAULT_RULES="evdev" export XKB_DEFAULT_LAYOUT="us,us" export XKB_DEFAULT_OPTIONS="caps:ctrl_modifier,shift:both_capslock_cancel" as did setting my XDG_RUNTIME_DIR to something reasonable (in my case it was /tmp/xdg-runtime-dir). i also remember using "/usr/local/bin/libinput debug-gui" to help debug this. i setup my init script to spawn a terminal then this program which helped a lot. hope this helps! -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA
