This is what I get if I run a kernel newer than 3.13: https://www.youtube.com/watch?v=nx2-Fvihzxg sorry for the link, I just don't know how to describe these artefacts verbally. (a storm of small horizontal moving blips from right to left ??) Those artefacts appear as soon as new kernel is selected in GRUB, and remain during the whole session. The lastest kernel (from the main repository that is) working without artifacts is v3.13.0.59. All later kernels have artifacts. All later kernels also are either "-utopic" or "-vivid" instead of "-trusty", but I do not know if it is related. GPU: Mobility Radeon HD 3200 (RS780M) System: Ubuntu Mate 14.04.2 32-bit Kernels tested: 3.13.0.59 (and earlier) , 3.16.0.45 , 3.19.0.25 Only 3.13.0.59 (and earlier) are without problems. ** Affects: linux-meta (Ubuntu) Importance: Undecided Status: Confirmed -- [ubuntu 14.04.2] Artefacts in radeon driver on kernel 3.16 and upwards https://bugs.launchpad.net/bugs/1479136 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-meta in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
