problems playing videos unless mouse pointer is constantly moved...

[pc.maint]

This problem was evident in 12.04, 12.10 and 13.04 (all using GNOME).

When watching video (online with Firefox or local using videos 3.6.3 or VLC 2.0.6), the video will stop and the soundtrack stutters (seems to be in a short loop). This fault goes away if the mouse pointer is constantly moving. At the same time that the video is stopped, the clock in the Indicator Applet also stops. Still happens when using SNA.

Use Xv and don't use unity.

pc.maint, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-intel REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.

Thanks for the response. That laptop now has Debian Wheezy on it (which works fine). I will get it back and try as you suggest.

Thanks again...
