Asus V502LX is the persian version of the Asus K501LX. Difference are minimal such as the keyboard (it has a persian keyboard which doesn't have backlit).a
I installed Ubuntu 14.04 because I trust more LTS version.a
To install the last version of the nvidia driver, you add the repository ppa:graphics-drivers/ppa
sudo add-apt-repository -y ppa:xorg-edgers/ppasudo apt-get updateThen
Let’s be sure that bumblebee is not install, you check in synaptec and you enter that command anyway
sudo apt-get purge bumblebee* primus libvdpau-va-gl1Then you installed Prime
sudo apt-get install nvidia-prime mesa-utils vdpau-va-driverThen
you installed the addon drivers nvidia-355, if it's not offered through the settings (software and update), you can enter the command
sudo apt-get install nvidia-355and then you enter
sudo apt-get install nvidia-settingssudo rebootIt works, your two graphic card are good to go. You can change it from the Nvidia setting and then reboot. You can also install prime-indicator
sudo add-apt-repository ppa:kranich/cubuntusudo apt-get updatesudo apt-get install prime-indicatorbut I don't recommend it because it only logout/login and that work only from Nvidia to Intel, to change from Intel to Nvidia, you need to restart or you'll face an error.
If you can't control the brightness, just follow that,
(source :
http://ubuntuforums.org/showthread.php?t=2028269 and
http://itsfoss.com/fix-brightness-ubuntu-1310/)
In /etc/X11/xorg.conf
add
Option "RegistryDwords" "EnableBrightnessControl=1"below
Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:4@0:0:0"
and, in /usr/share/X11/xorg.conf.d/20-intel.conf
sudo gedit /usr/share/X11/xorg.conf.d/20-intel.conf
add
Section "Device"
Identifier "intel"
Driver "intel"
BusID "PCI:0@0:2:0"
Option "AccelMethod" "SNA"
Option "Backlight" "intel_backlight"
EndSection
For me, the brightness works now in the settings in both nvidia and intel, but the hotkey (fn f5/f6) are not yet working.
You can add a shorcut linked to the following command in order to decrease brightness
xbacklight -dec 10and an other one to the following comand to increase brightness
xbacklight -inc 10If you don’t want the brightness to start at maximum, open the “Startup Applications” and add a new startup item with the command:
xbacklight -set 40(40 is for 40 % but you can set the one you want)
For the wifi/airplane hotkey, the only one which is not working with the brightness, follow that (source :
http://forum.ubuntu-fr.org/viewtopic.php?id=1770081)
sudo gedit /etc/default/grub
Replace in the file, the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"by
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="Save it and then you add this command in your terminal
sudo update-grubRestart the computer and the hotkey should work. For me, all work except the brightness.
To make the touchpad working properly,
You could either
install the driver
sudo add-apt-repository ppa:hanipouspilot/focaltech-dkms
sudo apt-get update
sudo apt-get install focaltech-dkmsThen reboot, or do this to get things working instantly, as documented in README:
Code:
sudo modprobe -r psmouse
sudo modprobe psmouseor update the kernel
I followed this threat,
https://forum.ubuntu-fr.org/viewtopic.php?id=1891911Install Kernel and
http://www.yourownlinux.com/2015/08/how-to-install-linux-kernel-4-1-6-in-linux.htmlIt Works! You've got a small error when the computer start, “Error parsing PCC subspaces from PCCT” because of a conflict between the new kernel and the nvidia driver but nothing to worry about. It just slow down a little bit the boot time.
Don't expect pinch to zoom or rotation with two fingers…
Only one problem so far, the touchpad is not working after you suspend your computer.
If you suspend the activity of your computer, you’ll need to restart.
However, if it gives a clue, before suspending ( it doesn’t work after I suspend the computer) I can deactivate and activate again the touchpad with the hotkey of my keyboard.
I found that but it doesn't help too much so far,,
http://ubuntuforums.org/showthread.php?t=2182922&page=2It gave a solution to a similar problem :
create a file here /etc/pm/sleep.d/0000trackpad
sudo gedit /etc/pm/sleep.d/0000trackpadand add
#!/bin/sh
case "$1" in
suspend|hibernate)
modprobe -r psmouse;
resume|thaw)
modprobe psmouse;
esac
Save it.
Now, the computer will refuse to suspend so no risk to loose your keyboard. However, you can't suspend your computer... tricky choice.
Some people have the same problem with Elantech keyboard on other computer,

My keyboard is a Focaltech.
I file a bug here
