I tried using Unity instead of gnome-shell and am experiencing the same problem. Does this mean it's not a problem with mutter? What is worse, is that this problems seems to crop up every day or so during work. In other words, everything will freeze except for the mouse even if I've never watched a video.
Could you please tell me details on how to get the best debug information for you? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1752145 Title: system freeze after full screen video viewing with Xorg on ultrawide monitor Status in linux package in Ubuntu: Incomplete Status in mesa package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete Bug description: 1. open a video (either youtube or totem) 2. put it in full screen. 3. wait Eventually (within minutes) the system will freeze in one of 2 ways. 1.
