I am experiencing some severe screen tearing on Chrome on 16.04. My PC has an AMD APU (A4-3400 with Radeon HD 6000 graphics) and I am not able to install proprietary drivers for it because it causes the login screen to reset, so I prefer to stick with open-source drivers.

I tried to turn-off hardware acceleration, which was indicated here

sudo lshw -c video output:

  • I don't think the AMD drivers have been ported over to 16.04 and I think the open source drivers are not the best. My genuine advice would be to install an nvidia card and don't look back. Failing that, take a look at using Compton as your compositor, I have had pretty good results regarding screen tearing with it.

  • The latest driver version for my APU was 15.9 and, YES, it is NOT been ported to 16.04 LTS as they are only available for 12.04.4 LTS and 14.04.2.

  • ... And I don't think also that my CPU can bottleneck a GT 1030 or GT 730.

I have three suggestions for you:

Install updated open source video drivers

sudo add-apt-repository -y ppa:oibaf/graphics-drivers
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install amd64-microcode

This will update open source video AMD driver to more recent version and install CPU microcode

Disable DRI3 acceleration for Chromium based browsers

echo 'export LIBGL_DRI3_DISABLE=1' >> ~/.profile
# restart after doing this

Try the most recent optimized kernel from XanMod

echo 'deb http://deb.xanmod.org releases main' | sudo tee /etc/apt/sources.list.d/xanmod-kernel.list
wget -qO - http://deb.xanmod.org/gpg.key | sudo apt-key add -
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install linux-xanmod-4.11

  • Disabling DRI3 acceleration dosen't help. I am not able to update the microcode since our Internet speed here in the Philippines is very, very slow.

  • Linux without internet is just something impossible. The only major distribution that has complete set of packages on DVD is CentOS.
