Matthew Brooks, the issue you are reporting is an upstream one. Could you please report this problem following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel to the appropriate mailing list (TO Rafael J. Wysocki and Len Brown CC linux-acpi)? Please provide a direct URL to your post to the mailing list when it becomes available so that it may be tracked.

[Bug 1651629] Re: [Asus X200MA] Brightness keys don't work.
With just "video.use_bios_initial_backlight=0", the brightness keys do nothing, and the gnome brightness slider works. With just "acpi_osi=", the brightness keys are recognized, and the brightness meter changes, but the actual screen brightness doesn't change at all. The gnome brightness slider also doesn't change the brightness when using this parameter. With just "atkbd.softraw=0", "showkey -s" produces no output when pressing the backlight keys. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1651629 Title: [Asus X200MA] Brightness keys don't work.

[Bug 1651629] Re: [Asus X200MA] Brightness keys don't work.
Using "acpi_backlight=vendor" and also creating the "80-backlight.conf" file with the contents shown on that page, results in the brightness keys still doing nothing, and the gnome brightness slider not working. The /sys/class/backlight/intel_backlight/brightness file still works fine though. I think that's everything in the workaround section there. But let me know if there's anything else I need to check or anything. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1651629 Title: [Asus X200MA] Brightness keys don't work.

[Bug 1651629] Re: [Asus X200MA] Brightness keys don't work.
Booting with "acpi_backlight=vendor", the brightness keys do nothing, and the gnome brightness slider breaks. The /sys/class/backlight/intel_backlight/brightness file still works. I don't know if it's important, but the "max_brightness" is 7812, which might be an unusual range. Setting brightness to 8, as recommended by the workaround steps, makes the screen way too dark to see anything. I usually have it at about 4000 or so. Anyway, I'm attaching the "vendorbacklight" and "lslabacklight" files that where generated, and I'm going to test the atkbd.softraw-0 parameter next. I'll report back with it's results. ** Attachment added: "vendorbacklight" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1651629/+attachment/4794923/+files/vendorbacklight -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1651629 Title: [Asus X200MA] Brightness keys don't work.
