Comment 3 for bug 962773

>>> To eliminate one hypothesis, I followed the instructions from https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-openchrome/+bug/760743/comments/11 . However, nothing happened. This is what i did:

$ sudo apt-get update

$ sudo apt-get purge xserver-xorg-video-openchrome

$ sudo apt-get install build-essential autoconf automake1.9 libtool git xutils xutils-dev subversion checkinstall

$ sudo apt-get build-dep xserver-xorg-video-openchrome

$ mkdir compilations

$ cd compilatons/

$ svn checkout http://svn.openchrome.org/svn/trunk openchrome

$ cd openchrome/

$ svn update -r920

$ ./autogen.sh --prefix=/usr --enable-debug --enable-xv-debug

$ make

$ sudo checkinstall -D

>>> At this point I received this message:

 *****************************************
 **** Debian package creation selected ***
 *****************************************

 *** Warning: The package version "0.2.904
 0.2.904
 0.2.904

 *** Warning: debian policy compliant one. Please specify an alternate one

>>> So, I typed:

 0.2.904

>>> In the end, I received this message, saying that installation was ok:

 **********************************************************************

  Done. The new package has been installed and saved to

  /home/flaviano/compilations/openchrome/openchrome_0.2.904-1_i386.deb

  You can remove it from your system anytime using:

       dpkg -r openchrome

 **********************************************************************

>>> Next, I edited xorg.conf:

$ sudo nano /etc/X11/xorg.conf

 Section "Device"
  Identifier "Configured Video Device"
  Driver "openchrome"
 EndSection

>>> So, I restarted my notebook, but I got another freeze when I tryed to play a video. The least bad workaround was disable "dri" in xorg.conf, like this:

$ sudo nano /etc/X11/xorg.conf

 Section "Device"
  Identifier "Configured Video Device"
  Driver "openchrome"
 EndSection

 Section "Module"
  Disable "dri"
 EndSection

>>> But I got a very poor performance. Now, there is no freeze and I can watch videos, but many of them are showed without audio synchrony. I installed Ubuntu Lucid in dual-boot and I have the same problems. In Bug #760743, the bug affects Ubuntu 11.04 and after and playing videos doesn't freeze ubuntu, but only make it restart. I don't know why, but Update r920 from openchrome trunk didn't help my problem too.

>>> If disabling "dri" freezes stops, maybe my problem is mesa drivers and not openchrome drivers. Any suggestion?
