Volume (+/-/Mute), Brightness (up/down), Disable Webcam, Mute Microphone and Projector Function keys are not working (when used through laptop keyboard) but Next, Pause/Play and Previous keys are working perfectly fine.
However, the volume/Brightness functions are working perfectly fine from an external USB connected keyboard.
gsettings reset org.gnome.settings-daemon.plugins.media-keys volume-down as suggested in one of the Ubuntu Forum threads. But this didn't help much.
This issue still exists after resetting all Keys through
I even tried using
gsettings set org.gnome.settings-daemon.plugins.media-keys volume-up "XF86AudioRaiseVolume".
There is no issue as such with the Keyboard since the F1-F12 keys associated with each key is working perfectly fine.
None of them are fixing this issue. Can you please help me get this fixed ?
