Hello !
I reinstalled Arch but on my SSD, and performance is amazing (4s boot vs 90s), however my keyboard and screen backlight have issues. I have nvidia driver installed, nvidiabl, asus-wmi. My DE is Gnome Shell. Laptop is Asus GL502VS.
Grub boot options :
tpm_tis.interrupts=0 acpi_osi=! acpi_backlight=native idle=nomwait
Keyboard backlight works fine at boot, but every suspend i got this issue:
Folder /sys/class/leds/asus::kbd_backlight is renamed to /sys/class/leds/asus::kbd_backlight_1
(and can't delete the last one)
Output of dmesg after suspend:
[ 106.656577] asus-nb-wmi asus-nb-wmi: Led asus::kbd_backlight renamed to asus::kbd_backlight_1 due to name collision
And screen backlight isnt working at all, xbacklight shows nothing, some events when i press function keys:
oct. 05 19:30:02 asus gsd-media-keys[886]: Failed to set new screen percentage: GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._gsd_5fpower_5fmanager_5ferror.Code0: Screen backlight not available
Posting more details after rebooting done, thanks in advance for any help

I would try to replace acpi_backlight=native to acpi_backlight=vendor.
If that doesn't work, try to adjust the backlight manually in /sys/class/backlight/*/brightness

Hi and thanks for your reply,
Tried to replace (already tried w/ vendor, works, video, doesnt seems, and native, same as vendor) but after freeze it seems to stop again.
Command
echo 1 >> /sys/class/backlight/asus-nb-wmi/brightness
does nothing, (btw only folder in .../backlight is asus-nb-wmi, i unloaded the kernel module but seems still here as i could read the name)
however when i try this:
echo 1 >> /sys/class/leds/asus::kbd_backlight_1/brightness
, keyboard light up.
(folder /sys/class/leds/asus::kbd_backlight/ wich is normally the original one and not renamed as you could see in dmesg, editing file brighterness does nothing, values go from 0 min to max 3)
Here's full dmesg with suspend https://pastebin.com/sDZvPGYE
Thanks for your time!
Edit: Solver by removing grub kernel parameters.
