Xorg.0.log VIVID - working
After updating the Ubuntu HWE stack in 14.04 to Xenial (kernel 4.4 and
xserver-xorg-video-radeon-lts-xenial), system boots up fine and responsively,
but screen is laggy; there is a tremendous performance regression in comparison
to xorg-lts-vivid. Lots of video tearing.
System is an older Pentium laptop (Packard Bell EasyNote) with a Radeon Xpress
200M chip (r300 driver). Video acceleration was working with DRI2 under the
Vivid stack (kernel 3.19-64-lowlatency + xserver-xorg-video-radeon-lts-vivid).
I also tried upgrading to the Wily kernel (4.2.0-lowlatency), and video
acceleration works fine.
I reported this in launchpad previously, and it was dismissed as "invalid"
since Wily is EOL.
The problem persists in the Xenial stack, so I'm reporting it here.
Attached are the respective Xorg.0 logs.</pre>
