Could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-3.14-rc7 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Summary changed: - Screen freeze during use of chrome/chromium + 8086:0a06 [Acer C720] Screen freeze during use of chrome/chromium ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: New => Incomplete ** Tags added: bot-stop-nagging ** Tags added: needs-upstream-testing regression-potential -- 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/1294391 Title: 8086:0a06 [Acer C720] Screen freeze during use of chrome/chromium Status in “linux” package in Ubuntu: Incomplete Bug description: I am using ubuntu 14.04 64-bit. (All my packages were up-to-date as of about 1 week ago.) My hardware is an Acer C720 (Intel graphics). The symptoms of the problem is the display completely stops updating, except the mouse cursor continues to move. Clicking and any keypresses have no effect. The system remains in this state for about 15-60 seconds, then it recovers and goes back to normal. The problem most commonly happens when using chrome or chromium to do any kind of intesive hardware-accelerated rendering. Typically a youtube video or and HTML5 game with lots of animations. The problem tends to happen during periods of high CPU usage.
