description |
After kernel update the backlight on my Asus eeepc 1005px becomes off during boot up. I can see the login screen if I point light to the screen. The backlight is not reacting on brightness adjustment keys. The backlight starts working only if I close and open the laptop lid.
I have tried to:
* echo 10 > /sys/class/backlight/acpi_video0/brightness
* echo 125 > /sys/class/backlight/intel_backlight/brightness
* vbetool dpms on
* pass "acpi_backlight=vendor" kernel parameter
* install gdm instead of lightdm
* create /usr/share/X11/xorg.conf.d/80-backlight.conf with content recommended in Kernel/Debugging/Backlight Wiki article
with no luck.
The backlight works fine if I pass "acpi_osi=" kernel parameter, the brightness is adjusted by keys, but the applet does not react to adjustments.

== SRU Justification ==
Commit 78f3ac76d9e5 ("platform/x86: asus-wmi: Tell the EC the OS will
handle the display off hotkey") causes the backlight to be permanently off
on various EeePC laptop models using the eeepc-wmi driver (Asus EeePC
1015BX, Asus EeePC 1025C).
== Fix ==
* 1dd93f87 (platform/x86: asus-wmi: Only Tell EC the OS will handle
display hotkeys from asus_nb_wmi)
This patch addes a .wmi_backlight_set_devstate quirk for specific
models to make asus_wmi_set_devstate(ASUS_WMI_DEVID_BACKLIGHT, 2, NULL)
conditional.
Only X/D contain the commit that introduce this issue (78f3ac76), this
patch can be cherry-picked into D.
For X, it needs some content adjustment to add quirks only to those
models that exist in Xenial tree.
== Test ==
Test kernels could be found here:
https://people.canonical.com/~phlin/kernel/lp-1837117-eeepc/
Bug reporter has verified that this fix works as expected on X.
== Regression Potential ==
Low, quirks limited to specific ASUS laptops and by far there is no
further change to this in upstream kernel.
