Public bug reported: Started off with a clean install of 11.10 then upgraded through the dash with "update-manager -d" to 12.04 to see if I could get rid of a performance problem that I'll detail below.
For the most part normal operation of the system is fine, what I'm observing could best be described as "stuttering" if I'm moving the mouse I'l often notice that it freezes for a quarter of a second then resume as normal, video playback suffers the same symptom. I had logged another bug here if it helps https://answers.launchpad.net/ubuntu/+source/xorg/+question/184689 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: xorg 1:7.6+7ubuntu7 ProcVersionSignature: Ubuntu 3.2.0-8.15-generic 3.2.0 Uname: Linux 3.2.0-8-generic i686 .tmp.unity.support.test.0: ApportVersion: 1.90-0ubuntu2 Architecture: i386 CompizPlugins: [core,bailer,detection,composite,opengl,decor,compiztoolbox,grid,place,vpswitch,resize,imgpng,move,gnomecompat,session,regex,snap,mousepoll,unitymtgrabhandles,wall,animation,fade,expo,scale,ezoom,unityshell,workarounds] CompositorRunning: compiz CurrentDmesg: Error: command ['sh', '-c', 'dmesg | comm -13 --nocheck-order /var/log/dmesg -'] failed with exit code 1: comm: /var/log/dmesg: Permission denied Date: Sun Jan 15 12:43:43 2012 DistUpgraded: Log time: 2012-01-15 00:10:41.611832 DistroCodename: precise DistroVariant: ubuntu ExtraDebuggingInterest: Yes, whatever it takes to get this fixed in Ubuntu GraphicsCard: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Samsung Electronics Co Ltd Device [144d:c06d] Subsystem: Samsung Electronics Co Ltd Device [144d:c06d] InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release i386 (20111012) MachineType: SAMSUNG ELECTRONICS CO., LTD.
