* Add ASUS ExpertBook B9406 display and touchpad fixes for Panther Lake * Drop B9406 migration Per DHH's review: the migration's audience is essentially nobody. Anyone running Omarchy on B9406 today is doing so via nomodeset manually at every boot, not via a working unmodified install. Fresh installs after this PR ships will pick up the fixes through the hardware-match install hook; no migration needed.

# Display fixes for ASUS ExpertBook B9406 (Panther Lake / Xe3 iGPU).
|
|
#
|
|
# Panel Replay is Xe3-new, default-on in the xe driver, and has a broken
|
|
# exit/wake path on this eDP panel: the panel latches the last-presented
|
|
# frame in self-refresh and never wakes for subsequent atomic commits, so
|
|
# the screen only updates on a full modeset (e.g. a VT switch). The older
|
|
# xe.enable_psr=0 knob does not cover Panel Replay.
|
|
#
|
|
# 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.
