Videos cause window to flicker

[davinci314]

I have 8.10 on my laptop with an ati mobility radeon x1400. I have installed and enabled the proprietary driver, yet all the videos I play (.avi, .mpg, and .wmv) flicker incessantly no matter what media player I use. I have tried downloading many codecs, but nothing seems to work. Many games also flicker or lag.

On a possibly related note: I also cannot seem to enable the cube option in compiz fusion. Although I have enabled it within the compiz settings, it still refuses to display. At first I theorized that it was because I only had two desktops enabled. I then discovered that 2 is all the desktops my computer will allow me to have. Although I can enable 4, and it will accept the change, I will still remain with only 2 desktops.

Can anyone please tell me what is going on here?

If you use VLC, goto Tools->Preferences->Video and set "Output" to X11 Video output. Click Save and restart VLC. That should solve the flicker problem.

Try EnvyNG for the graphics driver and see if it works: http://www.albertomilone.com/nvidia_scripts1.html

EnvyNG is in the repos.

sudo apt-get install envyng-core

Then you can run it from the CLI with

sudo envyng -t

As an alternative you could turn off Desktop 3d effects in System settings. X11 video driver uses the CPU to render the video. I dont think Envy will make any diffrence since the flickering is caused by the ATI driver.

Re: Videos cause window to flicker

Changing the output of my media players seems to have fixed the flickering during video. Thank you.

However, I am still having difficulties enabling the cube feature in compiz. Can anyone help me there?
