pb playing divx/xvid full screen

[darklord06]

Hello,

I recently installed ubuntu in my laptop (hp dv5000) and I am learning how it works (so far I like it !) but I have one main issue with the xvid or divx videos playback in full screen.

right after having installed ubuntu, I tried to play a divx video using totem, apparently the required codecs weren't installed so it automatically downloaded those, it was ok as long as I tried to play the video in window mode but as soon as I tried to play it full screen, it was noticeably more laggy than it was under windows seven.

I thought that it was maybe a problem with totem itself so I installed VLC (it supposedly has its own codecs) but i have the same problem with in in full screen mode, I also have difficulties moving the cursor using my touchpad in full screen mode.

i thought that it was a graphical card driver issue but i was no problem playing mkv videos in full screen, i only have a problem with xvid and divx videos.

I am completely new to ubuntu and if somebody could help me with it that would be very cool


if it helps, my laptop is an hp pavilion dv5000 with an amd turion 64 ML-32 1,80GHZ chipset, 1GB of ram and a ATI mobility radeon xpress 200 series 128mb graphical chipset

thank you

1st possibility: Turn off visual effects, if they are enabled.

I believe it should be
System -> Preferences -> Appearance -> Visual Effects

and select none.

2nd possibility: Change the video output.
For gstreamer based apps like Totem, I believe the you can change it by running

gstreamer-properties

For VLC, there should be an option somewhere under Video or Preferences.

You should be presented with a couple of options, such as Xv, X11, OpenGL. Try various ones.

thank you reed9 !!

I tried first to deactivate the visual effects and the full screen playback of divx/xvid videos aren’t isn’t laggy anymore, the only strange thing remaining is that if i keep the original aspect ratio for a 16:9 video, i have an horizontal line appearing on the upper side of the screen, when i switch to a 16:10 aspect ratio it disappears.
Again I have no problem playing mkv files in full screen even with advanced visual effects activated, I am really puzzled, I will try to change the video output and see what happens.
I would like to keep the visual effects and have xvid/divx files playback in full screen properly.

Thank you again

The x200 graphics card can be problematic. I have a dv8000 with that card, and when I first started with linux in late 2007, it caused no end of troubles. The open source radeon driver has improved greatly, but performance is still not so good. I never run special effects on it because of the performance hit.

MKV is a container format (which could contain an xvid encoded video), so the difference could also lie in how the MKV video was encoded.

I tried to install the ati proprietary drivers and after a reboot the xvid/divx playback issue disapeared but now, when i try to watch a flash video from firefox in fullscreen i get a "flsh plugin crashed" error message.
when i uninstall those drivers, the flash video playback is ok again, that's wierd.
