Mageia forum

Hi all

Two weeks ago I upgraded from Mageia 6 to Mageia 7. Since then I have tearings and nothing that helped in the past does help now.
In nvidia-settings I checked "Sync to VBlank", "Force (Full) Composition Pipeline", I did set a fix resolution and 60Hz. Apply -> restarted Firefox (but not every time) -> nothing changed.

Set "Sync to this display device" to my "Philips FTV (HDMI-0)". After a reboot the login manager didn't appear. So I changed this back. I do not exactly know, but I think this option seemed to work the first time I tried, but not the second time...?

My current xorg.conf:

How do I get rid of these tearings in Mageia 7?

Thanks in advance

I dont see in your xorg.conf the Composition.
For me tearing disapears when I add in Section "Screen" of my xorg.conf:

Code: Select all

Option         "metamodes" "1920x1080_60 +0+0 {ForceCompositionPipeline=On, ForceFullCompositionPipeline=On}"

A.

Adding Force(Full)CompositionPipeline didn't do anything. So I set "Sync to this display device" to "Philips FTV (HDMI-0)" and saved the changes to "xorg.conf". After a reboot Mageia didn't get to the login manager. So I copied the backup of "xorg.conf" back and now I don't have tearings anymore...

But in nvidia-settings there is still "Sync to ... Philips..." checked.

I don't know why it works - but it seems to work...

Hello

Can you please explain what

Code: Select all

ForceCompositionPipeline=On, ForceFullCompositionPipeline=On

do?

I have maybe a simillar effect.
After I e.G. play a game in full screen mode using OpenGL my screen gets partly black if I
start playing a video or typing.
I also have a Nvidia 1050 graphic card.

I googled a bit for this toppic but don't get a clue.
How can I be sure changes to Xorg.conf or nvidia settings are persisted

Regards

Tearings aren't gone. Seems there are less tearings now...

What else can I do?

@Spinnifex:
I don't think that these problems are the same...
Changes to xorg.conf are persistent (using nvidia-settings you have to save changes - therefor you must be root or save the xorg.conf to another location and then move it to /etc/X11/).

What kind of tearings? Plasma animations, gaming (wine), firefox, chromium? Are the tearings noticable in the youtube tearing videos?

Did you try to use XRender or switch the OpenGL in the Monitor settings of Plasma settings?

Sorry I forgot to mention I use Gnome3. The tearings are horizontal lines in videos (Firefox / Netflix, Totem (flv-file), tagesschau.de (News)).

Watched the Youtube tearing test (https://youtu.be/MfL_JkcEFbE) - yes I have screen tearings.

What is XRender?

Ahh you are using Gnome3. Hmm perhaps you can check Firefox settings and see, if hardware acceleration is enabled and also increase the number of processes it uses. Is your TV propely recognized in nVidia settings as HDMI connected, if so, maybe see the output of xrandr on what frequenceies and resolutions are available and force in xorg.conf some options after "metamodes" such as "HDMI-0" ... or something. Reinstall nVidia driver? Check if your monitor in MCC->Hardware->Graphical server setup section exists. I assume tainted and nonfree repos are enabled in your M7.
If it worked in M6, you should make it work in M7

Hmmm - today all seems fine. I think I have to see...
Hardware acceleration is enabled and it uses the maximum number of processes (8). In nvidia-settings the monitor is recognized as HDMI connected. In MCC it is recognized as "Plug and Play" monitor. I can't find my monitor (Philips 32PFL5605H/12). But I think this has been so in Mageia 5 and 6...

Tainted and nonfree repos are enabled.
