Tearing, vsync with Intel graphics

[MCMcButtah]

wow that pic is pretty bad. I get that on my desktop when I turn off deinterlacing, but not that bad. Have you tried bob in mythtv? I have only verified smooth playback with mythtv....have not tried mplayer. Kaffeine with uses the xine engine has been smooth, but I have not tried any high def video.

I am not sure if I am using the binary drivers or not. I didn't do anything really other than install kubuntu 7.10 and then upgrade my kernel to 2.6.23

I'm not even running MythTV, but I thought I'd try xvmc output from mplayer to see if it made it stop doing what's pictured above - and MythTV is a high-ranking search result when looking for xvmc info.

It's definitely not an interlacing issue - this affects all video, interlaced or not. And it doesn't seem to care what player's doing the playing.

I'm running the stock kernel in 64-bit Gutsy - I tried upgrading to the 2.6.23 in Debian per these instructions, but it didn't fix the video tearing and it knocked out my sound and wireless on top of that. Needless to say, I went straight back to stock.

I sure wish there was something that could be done about this issue. It's hard to explain to people the advantages of an open operating system like Ubuntu when I go to watch a video on my brand new Core 2 Duo and it looks like eight shades of garbage compared to a years-old Windows machine.

It's incredibly lame that I'd have fared much better by buying practically the same laptop, only with Vista and nVidia graphics, and then installing Ubuntu on it myself. When buying a machine with an operating system pre-installed on it, one assumes that it will work correctly. Apparently this is a naive assumption.

I am experiencing the same problem on Ubuntu 7.10 with "Mobile GM965/GL960 Integrated Graphics Controller" using the OGL ouput in VLC. Weird thing is I could never get vsync to work in OGL in Windows for VLC either. Any progress on this?

[fondle-em]

Don't think so. The relevant bug seems to have been reported:

https://bugs.launchpad.net/ubuntu/+s...el/+bug/152206

...so I added my two cents and what seemed to be the relevant portions of my xorg.conf and output from glxinfo. Hopefully it's of some use, as this bug really needs squashing.

Same problem here... tearing when i move windows, and during video playback.

[apauloisdead]

Bump.



Anyone find a solution?

Wobbly windows just isn't appealing with tearing...

I'm a bit of a linux noob myself, but has anyone tested to enable vsync using 'driconf' a tool you can find and dl using synaptic ?

*Bump*

I had forgotten about this post, till I tried watching a movie on my laptop today :-p I see there is still no fix for this. Good that someone has reported this bug, maybe we'll see a fix for it through synaptics or in Ubuntu 8.04 ... ?

There may be hope with Intel X 2.2.1 Driver

In Ubuntu 8.04 this problem is gone (Tested with 32bit)
