Re: Install linux in Lenovo Yoga 720?

I tried to install linux on the lenovo yoga 720 but had no luck. My approach was:

1. I disabled all security options in bios

2. Trying to boot the installer

3. Getting a black screen and fan went full power.

 

 I tried Ubuntu 16.10, the newest Kali Linux, Ubuntu 16.10 and Manjaro 17.0.1.

Also following boot options for the isntaller kernel didn't help:

nomodeset, noapic, nolapic, only-ubiquity

 

Ok I managed to install Arch Linux with a working Gnome.
Steps to reproduce:
1.Boot into windows and install all updates and create a recovery partition with systemdata on an usb drive

2.Change the SATA mode in Bios to AHCI
3.Wipe the complete disk and install ArchLinux in UEFI mode

4.Option to change BIOS to legacy is now available change it

5.Manjaro Linux disk will boot now and you can install in legacy mode

6.I decided to give it in UEFI mode another try, and changed the bios back to UEFI mode
7.Reinstall ArchLinux and this time it boots without problems.

Great job. Ive been eyeing the 720 for purchase, but dont want to risk it till I know linux will work.

How well does it work ? Any issues ? Do you think wiping the entire drive is required.

I don't know. The problem was that the Linux kernel simply didn't boot. It stuck exactly after loading the vmlinuz image. I thought it might be using another video output, but no mode setting could help me. You have definitely to change the sata mode (as else Linux won't recognize the drive) which will cause problems to the windows installation and you will probably have to change from UEFI to legacy back to UEFI. Things that work are: Wifi, Bluetooth, sound camera, keyboard special keys, deactivating the touch and keyboard in tablet mode, battery overview, USB-A port. I managed to playback videos with WiFi connection on 40% of the brightness for 5h, with still around 27% battery life left. This can be improved by configuring your distribution better. Things that I think I have to configure and will then work are autoscreen rotation. In Manjaro Linux if you rotate the screen the touchscreen is also rotated and works perfectly. In standard arch Linux it doesn't do that. Still investigating why. I haven't tested the usb-c ports as I don't have any hardware for them.

Yes, Ubuntu 16.04 works well on the Yoga 720 (minus trackpad), here's what I did to get a dual-boot configuration working (Windows 10/Ubuntu 16.04) Unfortunately wiping the drive is required.

 

1) In BIOS change the SATA option from RAID to AHCI (this will kill your Windows install) no need to disable secure boot or use the legacy boot mode (UEFI works fine)

2) Reinstall Window using bootable USB, delete existing partition then allocate however much space you would like to make available to Windows leaving the rest free space for ubuntu to partion during its install process.

3) Boot Ubuntu from usb, should boot up fine without the need for any special kernel parameters etc, typical install process works as expected

 

Everything works out of the box in Ubuntu except the touchpad/touchscreen, I searched for several days trying everything I could to get it working to no avail. Somewhere along the way I may have replaced synaptics packages with xinput which I believe is what made the touchscreen functionality start working as a touchscreen instead of a pointing(mouse like) device.

 

I'd love to get the touchpad working so if anyone has any suggestions they would be greatly appreciated.

Ubuntu 16.04 works well* on the Yoga 720 15", however in order to get it installed you will need to wipe the factory Windows installation.

 

I was able to get mine setup in a dual-boot configuration with the following steps:

1) Change SATA Controller option in BIOS from RAID to AHCI, no need to disable secure boot or UEFI boot mode

2) Install Windows 10 from USB, deleting existing partitions then create a new one while leaving free space for Ubuntu

3) Install Ubuntu 16.04 from USB, no need for special kernel parameters/boot options.

 

*Everything works as expected in Ubuntu except for the touchpad. I spent a few days trying everything I could find to no avail, any suggestions would be greatly appreciated!

Can't imagine. Probably only a technical or layer 8 problem.

Got Kali 2016.2 to boot into live mode after switching boot mode to legacy and storage from RAID to ACHI.

 

Touchpad and Wireless were not functional.

Touchscreen was functional

DPI too hight to use -  can change scaling in gnome-tweak-tool

 

Update 4/25/2017:

Used a USB-C to ethernet adapter to connect to internet.

Kali installed without issue.  Without an internet connection, Grub would fail to install

After install, trying to login caused the system to crash.

Performed a full apt-get upgrade dist-upgrade from recovery mode.  Fixed the crashing, wireless, and DPI issues.  Still have no luck getting the touchpad to work

Mealejan, just to make sure on this post, you were able to get the touchpad working on Manjaro Linux? I have not been able to get it working under Fedora, none of the drivers will bind to it, even when echoing the id into /sys/module

 

What kernel version/driver/etc did you use to get the touchpad to work?
