I've just upgraded the kernel to 4.4.0-34-lowlatency by installing the linux-image-lowlatency-lts-xenial package. Video acceleration works just fine combined with the xserver-xorg-video-radeon-lts-vivid (DRI2).
Problems begin when using xserver-xorg-video-radeon-lts-wily or xserver- xorg-video-radeon-lts-xenial. Tearing ensues, regardless of the presence of a xorg.conf config file to enable/disable options to improve framerate. Enabling DRI3 only worsens the performance regression, and accentuates tearing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1610591 Title: Video acceleration regression for Radeon Xpress 200M (r300) in xorg- lts-xenial & xorg-lts-wily To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-lts-transitional/+bug/1610591/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
