> hmm........ Takashi's patch works before, but doesn't work now? Argh ... sorry Takashi. Joey is right. I thought I had tested that, but apparently not. Indeed, your last patch prevents the backlight from being turned off, but it also breaks the brightness adjustment keys at runtime with acpi_osi=Linux. And without that it doesn't work, anyway, just like before. I'll add some more debug messages ... > Does that because my new patch for bko#34142 ? Could you please add > acer-wmi to /etc/modprobe.d/blacklist then reboot machine ? Done. No, your patch is not involved. But backing out Takashi's patch and re-applying confirmed that it's that patch. m.
