Brightness Adjustment for Yoga 13 – Ubuntu

You may have noticed that even though the brightness icon is appearing on your screen, it’s not actually adjusting the brightness. Here’s how to fix it.

From command line, run the following:

sudo gedit /etc/default/grub

Add the following lines to the end of the file.

#For adjusting brightness on Yoga 13
acpi_blacklight=vendor

Save and close the file.

From terminal, run:

sudo update-grub

Finally, blacklist the other device:

sudo gedit /etc/modprobe.d/blacklist.conf

Add the following lines to the end of the file. Save and close it.

#For adjusting brightness on Yoga 13
blacklist ideapad_laptop

Now, save your work and reboot.

Wireless Drivers for Yoga 13

I have a Lenovo Yoga 13 and love it, except for the fact that I couldn’t get wireless working on Ubuntu. That is, until now. Thankfully, a github user by the name of lwfinger has a solution. If you have an internet connection, via a USB dongle, simply perform the following in the terminal:

apt-get install git
git clone https://github.com/lwfinger/rtl8723au
cd rtl8723au
make
sudo make install
sudo modprobe 8723au

If you don’t happen to have internet connection, just grab this package and copy it to your home folder, then run the following:

tar xzvf yoga13realtekwireless.tar.gz
cd yoga13realtekwireless
make
sudo make install
sudo modprobe 8723au

lwfinger also has the Bluetooth driver if you visit his github site.
