Public bug reported: I used the command "watch -n1 cat /proc/interrupts". But when i pressed the brightness hot keys id didn't increased the interruptions. I also used the "acpi_listen" at that time it didn't feedback any output when i pressed the brightness hotkeys. Again I used "sudo showkey -s" it also didn't feedback any output.
But it's working on windows ** Affects: linux-oem-5.10 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1933761 Title: Brightness hotkeys(Fn+F5 for decrease and Fn+F6 for Increase) are not working on Ubuntu 20.04.
