Title: System Stutter When HDMI Monitor Is Connected Status in “xserver-xorg-video-intel” package in Ubuntu: Confirmed Status in “xserver-xorg-video-intel” source package in Precise: New Status in “xserver-xorg-video-intel” source package in Quantal: New Bug description: With a fresh install of Ubuntu 11.10 x64, the system has many "microfreezes" when I connect an external monitor via HDMI. These last maybe 10ms and occur about once per second. As I move my cursor around the screen, it stops motion during these microfreezes, causing a very irritating stutter effect. This only happens when using HDMI- when connected via VGA to an external monitor, the system behaves smoothly as expected. I started a thread about this a long time ago, but I never did find an answer: http://ubuntuforums.org/showthread.php?t=1817910 ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: xorg 1:7.6+7ubuntu7.1 Uname: Linux 3.3.0-030300rc7-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 1.23-0ubuntu4 Architecture: amd64 CompizPlugins: [core,bailer,detection,composite,opengl,compiztoolbox,decor,grid,move,vpswitch,place,mousepoll,resize,wall,regex,session,snap,gnomecompat,imgpng,animation,expo,workarounds,unitymtgrabhandles,ezoom,fade,scale,unityshell] CompositorRunning: compiz Date: Sat Mar 24 18:30:09 2012 DistUpgraded: Fresh install DistroCodename: oneiric DistroVariant: ubuntu ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Device [1b0a:2080] InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) MachineType: PEGATRON CORPORATION A15 ProcEnviron: PATH=(cususername, no user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.3.0-030300rc7-generic root=UUID=a19e39dd-b510-4f9d-93f5-de6d40df10f1 ro quiet splash vt.handoff=7 SourcePackage: xorg Symptom: display Title: Xorg freeze UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 06/17/2011 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 211 dmi.board.asset.tag: ATN12345678901234567 dmi.board.name: A15 dmi.board.vendor: PEGATRON CORPORATION dmi.board.version: 1.0 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 9 dmi.chassis.vendor: PEGATRON Computer Inc. dmi.chassis.version: 1.0 dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr211:bd06/17/2011:svnPEGATRONCORPORATION:pnA15:pvr1.0:rvnPEGATRONCORPORATION:rnA15:rvr1.0:cvnPEGATRONComputerInc.:ct9:cvr1.0: dmi.product.name: A15 dmi.product.version: 1.0 dmi.sys.vendor: PEGATRON CORPORATION version.compiz: compiz 1:0.9.6+bzr20110929-0ubuntu6.1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.26-1ubuntu1 version.libgl1-mesa-dri: libgl1-mesa-dri 7.11-0ubuntu3 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 7.11-0ubuntu3 version.xserver-xorg: xserver-xorg 1:7.6+7ubuntu7.1 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.6.0-1ubuntu13 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:6.14.99~git20110811.g93fc084-0ubuntu1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.15.901-1ubuntu2.1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:0.0.16+git20110411+8378443-1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/964231/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
