XF86MonBrightnessDown and XF86MonBrightnessUp present as XF86AudioMicMute
by claustrofiel from LinuxQuestions.org on (#5KJXF)
When I press XF86MonBrightnessUp (keycode 233) or XF86MonBrightnessDown (keycode 232), xev says I've pressed XF86AudioMicMute (keycode 198).
I have had this problem before at least twice. Both times it resolved on its own, but I don't know how.
I am using an up-to-date Slackware current on an HP Probook 440 G6 laptop.
I have bound the keysyms XF86MonBrightnessUp and XF86MonBrightnessDown to simple scripts that read from and write to /sys/class/backlight/intel_backlight/brightness.
