Hi,
I have a new Asus UX305FA notebook.
Everything works fine exept :
1. The fn+f2 key for the wireless bluetooth on off
(solved for now with a simple rfkill unblock all command)
2. The fn+f5 and fn+f6 brightness control keys
I checked with acpi_listen and xev, no event is generated pressing those keys.
Adding acpi_osi="!Windows 2012" in grub doesn't change anything.
Luckily, i discover with xev that the fn+f3 and fn+f4 generate events for
the brightness control so i mapped those in the KDE global shorcuts for now.
The f3 and f4 keys have no symbol on the keyboard and should be
unused with the fn+ combination.
The symbols for brightness control are on the f5 and f6 keys.
Attached are acpidump, dmidecode, dsdt.dsl and the ssdt6 tables.
I disassembled the dsdt with: iasl -e *.dat -d dsdt.dat
And the ssdt6 with: iasl -e *.dat -d ssdt6.dat
I discover that the brightness control method are in the ssdt6 table
and not in the dsdt. The PNPOC14 (WMI) is in the dsdt.
I also noticed this in the ssdt6 table at line 961 :
Name (AEXL, Package (0x04)
{
"svchost.exe",
"dllhost.exe",
"smss.exe",
"WinSAT.exe"
})
I dont now if that mather for my problems (i'am an average user).
If you need more info, just ask me.
