Zenbook UX303UB-DH74T w/ Core i7-6500U, 12GB, 512GB SSD, 13.3in QHD+, GeForce GT 940M
Mint 17.3 installed and updated
Optimus Driver nvidia-352 (recommended) will not boot.
two finger tap and Scroll does not work
three finger tap does not work
Screen brightness will not work (the hot keys) UNLESS I do this:
I tried upgrading the kernel to 3.19.0-56STEP 1:
The first is to edit the /etc/default/grub file
Go into Terminal and type:
sudo gedit /etc/default/grub
and change the line that says:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="
and then : update-grub
(I just copied and pasted the line below, made the change and then commented the original out with a # so that I knew what it was that I had changed)
NOTE: that there were a few different options to try with this line that I had found, but this was the only one that worked in conjunction with step 2 below.
ALSO NOTE: If you do ONLY Step 1, the slider will show up, but the screen brightness won't change. You MUST do step 2 ALSO to to get it to work!
This worked for intel based systems.
You can verify you have an intel setup by opening terminal and typing:
My system replied with:
(I am wondering if acpi_video1 would be the intel graphics card . . . will have to check it out some time)
Then you have to create a file (this was not in my system originally) by typing:
sudo gedit /usr/share/X11/xorg.conf.d/20-intel.conf
. . . and put this info into it:
Option "Backlight" "intel_backlight"
On a hunch I tried I tried upgrading the kernel to 4.4.0-13 (because I could get everything to work very very well with ubuntu 15.10 and kernel 4.2.0-30) but I'd really rather run Mint.
As such, my 2 finger tap was recognized, but nothing else imporved (on Mint 17.3 with this 4.4.0-13 kernel)
As I said, Ubuntu 15.10 with the 4.2.0-30 kernel I found that EVERYTHING works marvellously (though I did have to apply the screen Hot Key fix).
Suggestions, or should I wait with bated breath for the next Mint LTS to come out?
Does everyone expect that it will solve these problems?
