Linux Mint 16 KDE and nvidia - tearing [SOLVED]

Postby mbalazs81 on Thu Jan 09, 2014 11:58 am

hello

I have an nvidia 9600gt, no problem, nvidia driver working fine, but I always have to change the "scale method" in the desktop effects menu after the boot, otherwise, I see the tearing effect. Any idea?

I had tearing issues with Mint 13 which no amount of tweaking would fix apart from switching between open GL2 & GL3 on every boot (strangely enough it didn't matter which I chose as long as I actually did the change!) :?

Switched to the open source nouveau drivers and all the tearing went away.

For me the open source drivers perform perfectly in every way apart from I now have no hdmi sound. A problem I’m happy to live with since I’ve always connected audio directly to an amplifier anyway.

I don't know if the nVidia driver contains something similar but the ATI Control Center contains an option for "Tear free desktop" this option helped immensely for me.

I doubt this will help tearing but try raster as the Qt graphics system, it's a *lot* faster than native. See http://userbase.kde.org/Desktop_Effects ... ics_System

For me the thing that helped with using the nVidia driver is this:
In the /etc/X11/xorg.conf file I had to change a line in the screen section (at the end of the file) so it looks like this:

Option "metamodes" "nvidia-auto-select +0+0 { ForceFullCompositionPipeline = On }"

No idea what this means but since then the tearing is gone. I use a GTX 760 card, but maybe this could help you as well.

No more Windows and Gates since Ubuntu 8.04, used 9.04, 10.04, then switched to Kubuntu because of Unity and Gnome 3.
After that it is Mint, used 9 till 16 all in KDE version and loving it.

Is there any special setting for the youtube(flash 11.2) tearing? Everything fine, except this.
