Dear Listers, I just wanted to say thanks for the great support setting up my vaio VGN-Z590 with ubuntu - its running really well.
The only problem I have is when I'm playing video with the nvidia (speed) graphics card I get tearing of the video - horizontal lines due to some of the previous frame overlapping with the current one. see: http://www.omgubuntu.co.uk/2010/01/how-to-fix-video-tearing-in-videos-nvidia-ubuntu/for an example. I've tried a number of solutions found online including disabling compiz effects (set to none in the preferences), enabling sync to vblank, manually setting the refresh rate in compiz, but I can't seem to get rid of the problem. I'm using Ubuntu 10.10 amd64. The problem seems to be worse when I'm using 2 monitors withtwinview (the external over HDMI). However, I get no tearing in full screen openGL games (ie. quake3). None of the solutions I've tried seem to work and I was hoping someone on this listserv with the same hardware might have found a workable solution. Once, I thought the newest drivers might solve the problem so I tried using the janitor script to update the nvidia drivers directly from the ftp (newer than the distro drivers), however, this completely broke my install so I reinstalled ubuntu and then added the x-updates ppa: deb http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu maverick main Then I ran the janitor script and it was able to pull the latest drivers (270.18 as of today) from this ppa but this didn't solve the tearing problem either. I see it both with mplayer and VLC 1.1.7 (latest version as of today). Thanks very much, I'm really looking forward to solving this as I like to hook my computer up to my TV via HDMI to watch movies. -Lyle -- Lyle Gordon Department of Materials Science and Engineering Northwestern University 2220 Campus Drive Evanston, IL 60208 Tel: (847) 491-3584 Mobile: (847) 400-4071 [email protected]
