Hi, thanks for looking into this. I just installed the meta packages xserver-xorg-lts-vivid ( --install- recommends) and linux-generic-lts-vivid and rebooted
Running now: Xorg X Server version 1.17 (1:7.7+7ubuntu3-trusty1) vmlinuz-3.19.0-25-generic with options radeon.dpm=1 vt.handoff=7 the info I get from the xserver-xorg-video-radeon-lts-vivid package is: Version 1:7.5.0-1ubuntu2-trusty1 However, I still have the 'blipstorm' on my screen. Do I have the right kernel/Xorg/radeon-driver combination or are there any tweaks I can try ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1479136 Title: [ubuntu 14.04.2] Artefacts in radeon driver on kernel 3.16 and upwards To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1479136/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
