# Display backlight fix for ASUS Panther Lake / Xe3 iGPU laptops.
|
|
# Enabled only for ExpertBook B9406 and Zenbook UX5406AA for now.
|
|
# Other models need confirmation whether the issue exists there too.
|
|
#
|
|
# The panel's EDID on eDP-1 reads as empty, so xe takes backlight type from
|
|
# VBT (which says PWM) but the panel actually wants DPCD AUX backlight.
|
|
# Without xe.enable_dpcd_backlight=1, intel_backlight sysfs writes succeed
|
|
# but produce no visible change; brightness is effectively binary.
