BTW, I just finished testing the following scenarios, just to rule out a kernel-related issue: -Xserver: 1.18 -xserver-xorg-video-ati: 7.7
On kernels: -3.13.0-95 -3.16.0-77 -3.19.0-68 -4.2.0-42 -4.4.0-36 Video lags on all kernels. When using: -Xserver: 1.16 -xserver-xorg-video-ati: 7.5 on the above kernels, video and GUI respond smoothly. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in 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/xserver-xorg-driver-ati/+bug/1610591/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
