Bug Description

Binary package hint: xserver-xorg-video-openchrome

There's a problem with XvMC in the openchrome driver discussed in GentooBug 228473 (http://bugs.gentoo.org/show_bug.cgi?id=228473). There's a confirmed fix available for the problem. A merge of this fix into ubuntu would be good until this has been fixed in openchrome and ubuntu syncs with openchrome.

Two users have confirmed that the ioctlfix.patch from the gentoo bug fixes XvMC for their Ubuntu 8.10 systems.

Hi roband,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

As stated in the gentoo bug: there are no error messages in the Xorg log. This error appears in application's (mythtv) stderr:
ViaXvMC: Could not allocate timestamp blit area.

This bug is about merging an existing patch. No investigation is needed as I see it.

Are there any plans to release the fix for 8.04, or do i need to keep running the kernel from fiesty to have working XvMC under 8.04?
