video playing issue 7600gs

dtdave · 06-11-09, 07:59 AM

Hi, I have Ubuntu 8.10, 2 gigs ram, 3.4Ghz p4, and a 7600gs pci express and when I play videos whenever there is alot of motion, in that motion lines will appear like it cant refresh the video quick enough or something. horizontal lines. I figured out it must be the driver, I am using the nvidia latest 180 version and I have tested 177 and 173 versions to see if it changed anything and it didnt, I have changed my resolution, refresh rate even where i am on an lcd at 60 hz, I got it to go to 75hz and no change. The way I figured it was the driver is that for one, I had a cheaper card previously a fx5200 pci card and it didnt do it on it. I loaded windows xp on a seperate partition to test on, and loaded the latest nvidia driver from nvidia and it worked beautifully, no issues on windows. I like ubuntu better than windows and do NOT want to switch just to watch my movies or videos. Please HELP!!! Thank you!

Sounds like synctovblank issue.
If your player uses XVideo, check that "Sync to VBlank" is checked in nvidia-settings "X Server XVideo Settings" section. (enable it BEFORE starting your player)
If your player uses OpenGL, enable "Sync to VBlank" in nvidia-settings "OpenGL Settings" section. (enable it BEFORE starting your player)

sorry it took so long to reply but that fixed it! i had to enable it in open gl settings, it was already enabled in x windows. So what decides what i use, open gl or x windows. thanks for helping me with that, I am so excited it worked!!!!
