Okay, I narrowed it down to this: Running on bare recovery console without Xorg : no problem Running on bare normal (??framebuffered??) console without Xorg: blipstorm
The difference seems to me a loaded kernel driver...am I correct ?? If so, I could try out some new drivermodules or patches if you want me to. ( I have never patched or compiled kernel modules so I think I need a bit of hand-holding with this one ) -- 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
