Mrerexx, I can confirm this... I have the EXACT same laptop model (I rarely use nowadays) and just checked it. Indeed this model still has the same problems with the newer kernels.
Since this is an upstream bug, please follow this link [ https://bugzilla.kernel.org/show_bug.cgi?id=83461 ] and mention it there. I don't think many people (or developers) have hardware vulnerable to this bug so you might be asked to test some patches. In a few days I hope to be able to add some information there myself. -- 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/+source/linux/+bug/1479136/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
