My Nvidia Geforce GTX 850m issues are:
- Tearing on everything( window moving, video in Smplayer, video online in Firefox and Chromium, Scrolling in both Firefox and Chromium)
- no vsync settings on the Nvidia Xserver settings Window.
My driver and system info is:
- System: Ubuntu 15.04
- Processor: Intel Core i7-4700HQ CPU @ 2.40Ghz x 4
- Memory: 7.7 GiB
- Hard Drives: 1 TB
-
Graphics Card:
- Intel Corporation 4th Gen Core Processor Integrated Graphics Controller.
- Nvidia GeForce GTX 850m.
- Driver Version: 346.59 from nvidia-346-update
Its in Dual Boot with Windows 10.
What I've tried:
- xorg.conf configurations (triple buffer, usleep, powermizer maximum performance)
- X server settings (OpenGL: maximum performance, all antialiasing options all powermizer options)
ccsm
(Sync to Vblank, undirected, 120hz refresh rate)- I have basically tried everything I found with "nvidia" "ubuntu" and "tearing".
I had Linux Mint and had the same tearing issues, among other severe graphics issues (Random freezing, etc.). I have no issues till now with my nvidia card with Windows 10.
Anybody got a solution?
Best Answer
I had similar a problem with a K2000M on my laptop and using Linux Mint Cinnamon 17.2.
Expecially using a second monitor, video tearing appeared on my primary display.
The solution was to use
ForceFullCompositionPipeline
together withTripleBuffer
First do
sudo nvidia-xconfig
if the X11 configuration file xorg.conf is absent, thenand add the line
Option "TripleBuffer" "On"
under theSection "Screen"
:In order to be able to use ForceFullCompositionPipeline = On, one could modify the line
Option "metamodes"
in xorg.conf, but the problem was that when using a secondary monitor, the monitors.xml file (for the display manager) in ~/.config was overriding any modification issued by X11 reading xorg.conf at login (see here).The solution for me was to run a script at login (using System -> Preferences -> Startup Applications) with the following command:
where LVDS-0 is my primary display and DP-4 my secondary display (use
xrandr -q
for the display names)The last lines of /var/log/Xorg.0.log now shows:
and the video tearing disappeared...
Hope this helps on Ubuntu
