compiz|beryl periodic desktop freeze

[Vivian Stewart]

Binary package hint: totem

I was steaming video which was reportedly Xvid ffmpeg from a samba file share and at random times would freeze in a loop nothing responds(this ended up being my laptop overheating).

so disregard the above the real problem is in watching movies on a compiz or berylised desktop (openGL).

Thank you for your bug. What version of Ubuntu do you use? Do you use totem-gstreamer or totem-xine? Does it happen with any video?

[Vivian Stewart (vivichrist)]

feisty.

totem-xine

I will do some testing with other formats, so far only XviD ffmpeg iso mpeg4.

also video stuters when in compiz/beryl (opengl) aswell as freezing

probably unrelated but I get this in debug.log

How do you know it's doing a loop and not blocking? Could you try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash when hanging and attach the file to the bug report?

[Vivian Stewart (vivichrist)]

OK I'm changing this because in actual fact my laptop was just overheating.
however there is still a bug where video stops, audio continues and eventually video returns.
turn off compiz or beryl and all works without err.

[Travis Watkins (amaranth)]

Sounds like your laptop isn't fast enough to do video and compiz at the same time.

[Vivian Stewart (vivichrist)]

well I tested cpu monitoring with movie but average is 10 - 30%. At random intervals video drop-outs occur with 50-100% cpu utilisation, sudden and flat.

Turion x2 1.6 GHz TL-52, geforce 6150 integrated graphics.

could be the nvidia driver ... wouldn't surprise me ... turned off sync to VBlank in compiz, beryl & nvidia-config

[Vivian Stewart (vivichrist)]

further testing has lead me to the conclusion that this also happens at idle too so doesn't really implicate totem

[Vivian Stewart (vivichrist)]

this seems to be related to powernowd I now have full function

stopped the service in the services administration applet.
