[Desktop-packages] [Bug 1041790]
I have, I think, a reliable way to trigger this behavior, if that helps. It requires a non-trivial setup, though. I have gnome-shell running on dual monitors. The first is 1920x1200, the second is 1920x1080 (not sure if the resolution difference matters). If I run a full-screen game on The 1920x1200 monitor, I get freezes, and notes in the dmesg about hangcheck timers and kickrings (stuck wait on blitter ring). I believe OpenGL acceleration of the desktop is important, because the freezes are not triggered in fluxbox, for instance. I'm not sure if the game itself needs to be using OpenGL, or if the full-screen window is the triggering factor, or something else entirely. It is important that the game keep the monitors distinct, and only go full screen on one. I just tried it on Battle for Wesnoth, and full screen there sets the monitors to mirror, which doesn't trigger the problem. This is on an i7 4770, if that matters. I realize this is may be difficult to put together for a test setup, but I thought I'd mention it. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1041790 Title: [snb] GPU lockup IPEHR: 0x0b160001 IPEHR: 0x0b140001, workaround i915.semaphores=0 Status in X.org xf86-video-intel: Confirmed Status in “linux” package in Ubuntu: Confirmed Status in “sandybridge-meta” package in Ubuntu: Confirmed Status in “xserver-xorg-video-intel” package in Ubuntu: Triaged Bug description: X locks up periodically for a 2 to ten seconds at a time and this crash log gets generated. It's significantly more than several times a day but not quite continuous. Temporarily disabiling semaphores seems to eliminate the problem. E.g.: $ sudo -s # echo 0 /sys/modules/i915/parameters/semaphores [Workaround] 1. Edit your /etc/default/grub file. 2. Change this line: GRUB_CMDLINE_LINUX_DEFAULT=quiet splash to GRUB_CMDLINE_LINUX_DEFAULT=quiet splash i915.semaphores=0 3. Then run sudo update-grub 4. And reboot If you indeed have this bug, that should stop the lockups from happening. If it doesn't, then file a new bug report. Side Effects: Rendering throughput is dropped by 10% with SNA, or as much as 3x with UXA. OpenGL performance is likely to be reduced by about 30%. More CPU time is spent waiting for the GPU with rc6 disabled, so increased power consumption.

[Desktop-packages] [Bug 1115308] [NEW] Chromium webapps block functionality of other Chromium windows
Public bug reported: The chromium webapp plugin seems to cause some odd locked down behavior of other chromium windows. Steps to reproduce are as follows: 1) Launch a webapp in chromium. GMail or Google+ cause this, at least, for reference. 2) Open a normal chromium window The second chromium window will now not function properly. Typing anything into the omnibox and pressing enter will just clear the omnibox, not navigate anywhere. And keyboard shortcuts to open new tabs and jump to the omnibox (ctrl-t, ctrl-l) will not do anything. Presumably this is due to the webapp plugin locking down chromium to act like a stand-alone application, but it affects _all_ chromium windows opened after a chromium webapp (at least), not just the webapp window. The ill effects go away by closing all chromium windows.
