Happily running Ubuntu 15.10 Wily Werewolf on my Lenovo G50-45.

Update on 21/04/2016: Now more happy running Ubuntu 16.04

I purchased Lenovo G50-45 Laptop in December 2014 and installed Ubuntu 14.04 in dual boot with pre-installed Windows 8.1 as per this post.

When you install any Linux Distribution on a new Hardware it works but not 100% and there were following problems:
1. Screen brightness could not be adjusted.
2. Wifi was erratic.
3. Bluetooth did not work.

Screen Brightness worked after installing Realtek Proprietary Driver but it broke on update in April 2015. I removed the Proprietary Driver and upgraded to Kernel 3.16 through Hardware Enablement Stack which installed the Open Source radeon driver and problem 1 was solved.

Wifi problem was solved creating /etc/modprobe.d/rtl8723be file as follows:
 echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf
 For Bluetooth I had to wait till Ubuntu 14.04.3 was launched with Kernel 3.19 and it worked sometimes but not on every boot (I wonder why?) after adding following ppa and the driver:
sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtl8723au-bt-dkms rtlwifi-new-dkms linux-firmware
On questioning I came to know that I had to wait for Linux Kernel 4.2 when Realtek drivers are included.

On 9th Sep 2015 I came to know that Linux Kernel 4.2 was included in Ubuntu 15.10 and I downloaded the ISO and tried it on my Laptop as per this post. I updated the ISO for couple of days through zsync and it was booting properly every day.

Yesterday I decided to install Ubuntu 15.10 on my hard drive and found that installer crashed, however, I used the following workaround to run the installer and installed:
sudo -H bash -c 'ubiquity gtk_ui'
I am happy to report that there is no need to add any rtl8723be file for wifi, radeon driver is perfect and Bluetooth is working on installed Wily Werewolf.
