How can I change the screen brightness on Zenbook UX305 with media-buttons?
I am having the same problem with the newer UX305CA. Apparently it is really common since the hardware is not recognized, so I just assigned a new shortcut. Following this answer:
sudo apt-get install xbacklight
Then assign new shortcut:
- Settings > Keyboard > Shortcuts > Custom Shortcuts > +
Add those two:
- Brightness up:
xbacklight -inc 10 - Brightness down:
xbacklight -dec 10
Then click on each of the Disabled and select the new shortcut. In my case I used Alt+F5 and Alt+F6 (since I use Ctrl+F5 for web dev).
If you want, you can also mess with the boot options to fix it:
Hi,
I have the same problem. there is a workaround although.
add "acpi_osi=" at the and of the kernel boot parameters.
to permanently do this edit /etc/default/grub as root and add "acpi_osi=" at the end of GRUB_CMDLINE_LINUX_DEFAULT then run "update-grub" as root
after that brightness and all other hotkeys work but the ambient light sensor is no longer detected. But this is not a big problem since there is no standard ambient light regulation of screen brightness anyway
If you are interested by auto brightness for this notebook (through ALS sensor) it can help to you: https://github.com/Perlover/Asus-Zenbook-Ambient-Light-Sensor-Controller/tree/asus-ux305 It works at my Asus UX305 ;-) But you need to blacklist acpi_als module before
