Hello,

nobody?

Or are the information too inaccurate?

Best regards

I see this too on my desktop pc though with a ATI Radeon HD 4850.

Hi,

I installed Ubuntu 9.04 UNR on a Samsung NC10 netbook. These have an Intel 945GSE graphic card. The same problem with fast motions as on my Lenovo Thinkpad T500 with Ubuntu 8.10.

Best regards.

@Akagi, the phenomena with horizontal lines in fast moving scenes of movies is called "tearing" and it's a known issue.

Good news is that for textured video which is played back using the "xv" technology the issue has been fixed in the intel 2.7 driver version. Unfortunately this driver has published very recently (after we put together drivers for ubuntu 9.04 for example) so jaunty still has version 2.6.3 of the intel driver. Note that this concerns only "textured xv video" and it's only for intel cards. In the next version of ubuntu we will ship version 2.7 of this driver (or a later version) but if you want to experiment with this yourself you can install the 2.7 driver on Ubuntu today using the X-Updates PPA ( https://edge.launchpad.net/~ubuntu-x-swat/+archive/x-updates/ ).

Hello,

on Lucid this error can still be reproduced.

I have one (maybe) helpful discovery: If I add attach an external LCD monitor to my notebook and use a large virtual desktop, the tearing disappears.

Because of this I will upload two sets of logs with apport: The first set will be without external monitor and standard desktop, the second set with external monitor and extended desktop.

HTH!

Ok, upload failed:

Any suggestions?
