[ubuntu] How Ubuntu makes tear-free desktop?

linux-howto

http://ubuntuforums.org – Hello. I've worked with Ubuntu 12.04 and Ubuntu 10.04 and was admired that there is not any tearing even "from scratch" with default video drivers. I very apprectiate Ubuntu developers for this because i hate tearing. But now i need to configure one Debian Stable (squeeze) desktop (based on Gnome too), and it has tearing. Tell me, which settings in Ubuntu are responsible for tear-free desktop. I want to configure Debian's Gnome to achieve it on opensource drivers like it's done in Ubuntu. My videocard is ATI HD 4850. (Hardware)

Stories similar to [ubuntu] How Ubuntu makes tear-free desktop?

I am using Ubuntu 12.04(32-bit) and I installed the AMD Radeon drivers from the Ubuntu repos using Additional Drivers. After installing the proprietary driver I experienced a lot of screen tearing. So I enabled tear Free Desktop to reduce tearing. It has reduced the screen tearing a bit but it is still pretty bad.

I mean video files on my hard drive. I get noticeable screen tearing on VLC, Totem, gnome mplayer and Mplayer. I have tried fglrx drivers and now the experimental AMD drivers.

I have a Radeon HD6950 and enabling 'tear free' mode in catalyst removes the tearing but makes my videos have a strange motion, like a stuttery framerate.

Anyway to fix this?

Thanks.

I have to disable compositing in xorg.conf for video playback without tearing on my HTPC running vdpau with the binary nvidia drivers. Is it possible to have compositing enabled and still get perfectly smooth video?

Compositing seemed to make remote desktop very laggy also.

I have a bad tearing while watching video in Ubuntu 11.10. I tried to use both smplayer and vlc, but none of them helped. In fact I see tearing only in rips, there is not such problem while watching Blu-ray movies. Though maybe i'm just not very attentive. Can anybody help me with this? I have 32-bit version of Ubuntu. Videocard is GTX460 768mb. I use hardware acceleration in players (vdpau).

Ubuntu 12.10 beta 2 has awfull 3d performance and Video Tearing do something about this. Tearing is common issue on linux and makes linux sucks. Ubuntu also is bloated and uses compiz , i hope ubuntu developers should be more serious cause even a noob should know that compiz sucks now. I have no screen tearing and full opengl 3d performance on cinnamon ! And thats why i like linux mint 13. Ubuntu

[ubuntu] Screen tearing 2 years 4 weeks ago

I'm experiencing screen tearing in the upper 1/8 part of the screen. I have dv7-1190er laptop(video card is GeForce 9600M GT), OS is Ubuntu 10.10. "Sync to VBlank" is on in "NVIDIA X Server Settings"(both OpenGL and X Server XVideo settings) and in CompizConfig (General options -> Display settings ->Sync To VBlank).

Flash video tearing... 1 year 6 weeks ago

So when I'm watching YouTube/Crackle/etc. I'm getting video tearing...This is normally the issue that drives me back to Gnome.I guess one idea might be to try and install the latest Nvidia drivers? Or try installing Gnome? Anyone have any ideas?

Hi all,

since upgrading kubuntu 64bit to 12.10 i have tearing on the upper part of the desktop. i have vsync enabled both on nvidia panel and in system settings->desktop effects, in fact the same configuration was working fine up till now. i have the same problem with video on vlc (which was ok before, too) but not with kmplayer so i guess this is somethign i should ask on vlc forums...

Tearing happens while scrolling in nautilus.

Steps to reproduce: - View mode: list; (no tearing when other two modes are selected) - Mouse pointer has to be inside nautilus; - Scroll with mouse wheel (if you scroll slowly - you wont see the tearing);

Tested on 12.04 x64 and 11.10 x64. Default settings. OSS AMD drivers. Video graphics is ATI 3650m.

Can anyone reproduce this?
