I recently installed 17.04 on my desktop PC. Due to some technical constraints (I have a dual monitor setup and one them has only VGA adapter), I have to use both my RX480(primary monitor) and Intel HD4600. While RX480 has no problems whatsoever, I am seeing blocky tears/tearing on my monitor on HD4600.
I tried the following:
But to make matters worse, after adding the xorg.conf to /etc/X11
or alternatively 20-intel.conf to /usr/share/X11/xorg.conf.d
with the parameters
Identifier "Intel Graphics"
Option "AccelMethod" "sna"
Option "TearFree" "true"
I was stuck with the message on boot:
"/dev/sda1: clean, 121563/920272 files, 701079/3680256 blocks"
Adding GRUB parameter "nomodeset" disabled HD4600 and dropped the resolution on primary monitor to 800x600.
Am I doing something wrong? If not, what else I can do? Any kind of help is appreciated.
