** Tags added: latest-bios-f15 ** Changed in: xorg (Ubuntu) Importance: Undecided => Medium ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1405955 Title: Xorg freezes Status in xorg package in Ubuntu: Incomplete Bug description: After a few seconds the GUI disappears and I'm left with a CLI saying Radeon: Error couldn't schedule IB. This seems to happen more often when I'm running videos than under normal load. In this case I was running an mp4 file with h.264 video and AAC audio in VLC. More than willing to help figure out the issue, but I'm not sure I have the technical skills to compile the whole Xorg stack myself.
