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. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
