Brightness not working on Lenovo Yoga 11s


I just installed Linux Mint 16 on my Yoga 11s, but for some reason, the brightness doesn't work right at all. On boot, the brightness is set to 00, which makes the display completely blank. The only way I can use my system is to put the command "acpi_backlight=vendor" into grub. This will allow me to see everything, but I am still unable to control the brightness using the control keys or the applet. Strangely, I can change the brightness via the terminal by using command "intel_backlight XX," where XX is a number.

I would like to be able to control the brightness as normal, so would anyone be able to help?

Thanks.

Could you please let me know how you do it?

I also have a Lenovo Yoga 11S and I cannot figure out how to install Linux. The screen goes black, so how can you modify the grub before installing?

I am booting from a UBS stick that was configure using unetbootin

Thanks for your attntion and thanks for sharing your knowledge.

How to get a Yoga 11s to work with Linux?

Summary:
-On USB boot use "ESC" to make menu visible. Use "fn" "F6" to enter the boot parameters. Enter "i915.invert_brigthness=1" and start Ubuntu.
After installing Ubuntu and restart use "e" to enter the boot menu. Search for "quiet splash" and enter "i915.invert_brigthness=1", press "fn" "F10" to start.
- After starting change /etc/default.d/grub, line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.invert_brigthness=1 acpi_osi=Linux acpi_backlight=vendor"
- additionally create /etc/X11/xorg.conf with the contence:
Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "sna"
Option "Backlight" "intel_backlight"
Endsection
- LED backlight should work and brightness keys show work to.
- Network. Download ZIP file from github.com/lwfinger/rtl8723au. Extract. Update resources:
sudo apt-get update
Install:
sudo apt-get install make gcc linux-generic linux-headers-generic linux-image-generic
In terminal switch to the folder with 8723au. Type:
make
sudo make install
sudo sudo modprobe 8723au

By now most of the things show work.

Long version:

1. Display
Depending on you Yoga 11s you might see nothing when starting a USB stick with Linux. You should try Fedora (19 or 20, worked like charm) because it has less problems with the screen. Due to a bug or whatever all other distros I tried failed with the display.
If you want to use Ubunut or Kubuntu you should try the following:

- Try to get a bootable USB stick with (K)ubuntu 13.04 or 13.10.
- To start your USB have to change your system settings. There might be several ways to do so. I had to do the following: On the left side of the ON button is a very small black button. You need a pencil or something to get it pressed when starting the Yoga 11s. On some system the "F2" function key might work (pressing "fn" and "F2" simultaniously). Now you should enter the bios, where you can change the following settings:"Boot"-menu, find "Boot Mode" and change it from "UEFI" to "Legacy Support"; "Boot Priority" set to "Legacy first" and of course enable "USB Boot". May be you have to check the menu "Configuration", item "USB Legacy" - "enabled".
If this is done you can save the settings and restart the computer. Press "fn" and "F12" to enter the boot option. Now choose you USB HDD- Stick and boot into (K)ubunut.

- If the little icon is shown at the bottom of the screen press "Esc" and (K)ubunut will switch to the menu. Now press "fn" "F6" to enter the boot parameters. Press "Esc" to leave the dialog box. Now how should see a bootoption line above the function key listing at the bottom of the screen. Your cursor ist placed at the right side of this line, behind the "....initrd.lz quiet splas --" . Now write:

i915.invert_brigthness=1

Press "fn" "F10" and boot into (K)ubuntu. The above parameter prevents the graphic driver to turn off you LED background light. (K)ubuntu should start and you should choose the "Try (K)ubuntu" option. Later on we will put some bootoptions into the grub file, as well as creating a xorg.conf file for the sleep/recover mode.

- By now we need the internet and we don't have a driver for the 11s. So if you are a lucky owner of an Android phone, you might have an USB tethering. If so, just turn it on and connect your phone via USB with the Yoga 11s and you should have a network connection emediately.
- Well, you should see everthing on your screen, have an internet connection, now you should kill you hard drive (ssd) and format as you want. May be it's possible to work wth an dual boot but I didn't try that, that means, get rid of windows 8. After formating you go ahead installing the Linux system.

- After installing you'll get problems to start (K)ubuntu, just try to boot with the above bootparameters as follows: At the bootmenu press e to switch to commandline editing. Search for something like "splash quiet " directly behind this to words you should type the above mentiones parameter: i915.invert_brigthness=1. Press enter and boot (K)ubuntu.

To make the change permanent, you need to place the parameter in /etc/default.d/grub. The easiest way is with an editor. Yes I am lazy, no vi, just mc. Install: sudo apt-get install mc, is't the mightnight commander. sudo mc and change the directory to /etc/default.d click on the file "grub", choose an editor of your choice (I like no. 3) and change the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.invert_brigthness=1 acpi_osi=Linux acpi_backlight=vendor"

Save the file and exit mc. Don't forget to use the command: sudo update.grub
otherwise the change won't happen and nothing will work. Be careful not to mix up letters as I did (brightness/brigthness).

- Next we need to create an xorg.conf file in the directory /etc/X11. The contence should be like this:

Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "sna"
Option "Backlight" "intel_backlight"
Endsection

This is needed to turn on the backlight if the computer was in sleeping mode and to change the brightness setting either with the Yoga keyboard or with the engery control.

- Now it's time to get rid of the Android network connection. We need the driver for our wlan card and can get them from

github.com/lwfinger/rtl8723au

Have a look at the right side there should be a "Download ZIP" button. Save the file and after the download unzip it. Open a terminal. If you work with Kubuntu open dolphin and press "fn" "F4" to enter the terminal mode of dolphin.

-Before we procede we have to secure to have everything installed before building the driver. Some files we need might be missing (e.g. gcc) so we should update the repositories first with:

sudo apt-get update
sudo apt-get install make gcc linux-generic linux-headers-generic linux-image-generic

Now please restart your computer and continue with the terminal mode. Change to the folder containing the 8723au files. Type

make
sudo make install
sudo modprobe 8723au

By now your Android connection is gone and you have to choose your wlan connetion and parameters.
