[Bug 172261] Brightness keys FN+5 FN+6 not generating acpi events on Asus e200ha laptop
https://bugzilla.kernel.org/show_bug.cgi?id=172261 Zhang Rui changed: What|Removed |Added Status|NEEDINFO|CLOSED Resolution|--- |DOCUMENTED --- Comment #8 from Zhang Rui --- First of all, I don't think this is an ACPI bug as there is no ACPI interrupts when pressing these hotkeys. Usually, this is a feature gap that some platform specific drivers fail to catch these events and expose to userspace. Eventually, some guy may introduce this feature to Linux by reverse engineering or something else, but I don't know when. And for this issue, the best way is to raise it to Asus to provide Linux support for this.

https://bugzilla.kernel.org/show_bug.cgi?id=172261 --- Comment #1 from g...@flydando.com --- As a matter of reference FN+10, FN+11 and FN+12 do all generate events when using acpi_listen. These keys are mute, vol down and vol up. acpi_listen output when using the above keys: gavin@gavin-E200HA:~$ acpi_listen button/mute MUTE 0080 K button/volumedown VOLDN 0080 K button/volumeup VOLUP 0080 K All other FN keys generate no output. The following is a list of FN keys that are not working: FN+1 Sleep FN+2 Airplane Mode FN+5 Decrease brightness FN+6 Increase brightness FN+7 (Erm .. icon is a box with and X in the middle) Not sure. FN+8 Switch Displays FN+9 Disable/enable touchpad Please let me know if I can provide further information. -- You are receiving this mail because: You are watching the assignee of the bug. -- ___ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
