nvidia tearing

[snerk]

spadge, im using vlc, however its not just when i watch movies, its whenever something moves on the screen, for example if i scroll a website or move an application around. heres an example stolen from another forum, http://i.imgur.com/K3X5EDi.jpg
for me it only happens in the upper third of the screen though

Yeah, I know that it's in everything. I had the same problem last year, works fine now. Although I still have to be really careful with video playback as it's quite the different beast.

Have you got nouveau blacklisted?

[snerk]

hmm, how do i find out? and i still dont know why 'additional drivers' claim that no proprietary drivers are in use on this system, ive instlaled/activated nvidia drivers twice

[Spadge]

grep 'nouveau' /etc/modprobe.d/*

I think an lsmod (as root) should do it too.

[snerk]

i get this

/etc/modprobe.d/nvidia-313-updates_hybrid.conf:blacklist nouveau
/etc/modprobe.d/nvidia-313-updates_hybrid.conf:blacklist lbm-nouveau
/etc/modprobe.d/nvidia-313-updates_hybrid.conf:alias nouveau off
/etc/modprobe.d/nvidia-313-updates_hybrid.conf:alias lbm-nouveau off
/etc/modprobe.d/nvidia-graphics-drivers.conf:blacklist nouveau
/etc/modprobe.d/nvidia-graphics-drivers.conf:blacklist lbm-nouveau
/etc/modprobe.d/nvidia-graphics-drivers.conf:alias nouveau off
/etc/modprobe.d/nvidia-graphics-drivers.conf:alias lbm-nouveau off

I don't think anyone has believed what that little Additional Drivers doohickey has said for *years*.

Mine says 313 is activated but not currently in use, and that no proprietary drivers are present. It's lying. Clearly:

[Spadge]

Try setting Compositing type to Xrender instead.

Just wanted to say a big thank you - this worked for my wierd screen display of... "scrambled" pop ups
You could see them but there were blocks of multi coloured lines/waves

There must be something *VERY* wrong with your video card and/or drivers.

[snerk]

so ive been running compiz/emerald for a day or so now. compiz from the repos and compiled emerald as described here http://askubuntu.com/questions/28705...tu-13-04-64bit

result: no tearing whatsoever
but i cant get shadows under menus...i much prefer kwin i must say. i hope this can be fixed as soon as possible or somebody finds a hack for it

Compton

I have found the perfect tearing killer. It's Compton.

First install it from http://launchpad.net/~richardgv/+archive/compton

Create a script like this:

#!/bin/bash

#turn off composite
RESULT=`qdbus org.kde.kwin /KWin org.kde.KWin.compositingActive`
if [ "$RESULT" = "true" ]
then
  qdbus org.kde.kwin /KWin org.kde.KWin.toggleCompositing
  sleep 1s
fi

#compton is a X compositing window manager (force vsync, no tearing)
#http://launchpad.net/~richardgv/+archive/compton
#http://github.com/chjj/compton
compton --backend glx --vsync opengl-swc&
sleep 1s

#run your game
cd /path/to/your/game
./your_game

#restore composite state
kwin --replace&

Run the game or application using this script and compton will replace kwin while it's running. It will be tearing free.
