Title: Window updates are much slower under 12.04 than 10.10 Status in “gtk+3.0” package in Ubuntu: New Bug description: See question #195487, which I think was wrongly assigned to xserver-xorg-video-nv. https://answers.launchpad.net/ubuntu/+source/xserver-xorg-video-nv/+question/195487 To rehash question #195487: I just upgraded from GNOME 2.32 on a PPA- loaded Maverick 10.10 to 12.04 using GNOME Classic No Effects. Window updates are noticeably slower in apps like gnome term, pysolfc and nethack-x11, while some gtkperf tests are significantly slower on my machine than on my wife's slower machine. I ran it under all of the Unity and GNOME variants and the times weren't significantly different. This is a list of the significantly slower gtk operations (along with a couple of faster operations): http://pastebin.com/M0Ed92Ta We both have the nvidia 295.40 driver installed. She still runs a PPA-loaded Maverick system. My system has an Athlon II X4 640 CPU with GeForce 210 GPU while she has a Phenom II X2 555 with 8400GS GPU. Does screen size matter? The monitor, video card and binary driver are the same today as they were 48 hours ago (when I upgraded). I get 3400fps in glxgears and Tux Racer responds well, so it's NOT bug #982485. It was a clean install from the 64 bit Live DVD, so there's . (Since /home is on it's own partition, I'm able to upgrade w/o much worry.) # lshw -C display *-display description: VGA compatible controller product: GT218 [GeForce 210] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a2 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:18 memory:fb000000-fbffffff memory:b0000000-bfffffff memory:ce000000-cfffffff ioport:ef00(size=128) memory:c0000000-c007ffff # lsb_release -a LSB Version: core-2.0-amd64:core-2.0-noarch:core-3.0-amd64:core-3.0-noarch:core-3.1-amd64:core-3.1-noarch:core-3.2-amd64:core-3.2-noarch:core-4.0-amd64:core-4.0-noarch:cxx-3.0-amd64:cxx-3.0-noarch:cxx-3.1-amd64:cxx-3.1-noarch:cxx-3.2-amd64:cxx-3.2-noarch:cxx-4.0-amd64:cxx-4.0-noarch Distributor ID: Ubuntu Description: Ubuntu 12.04 LTS Release: 12.04 Codename: precise # uname -a Linux haggis 3.2.0-24-generic #37-Ubuntu SMP Wed Apr 25 08:43:22 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux # dpkg -l | grep nvidia ii nvidia-common 1:0.2.44 Find obsolete NVIDIA drivers ii nvidia-current 295.40-0ubuntu1 NVIDIA binary Xorg driver, kernel module and VDPAU library ii nvidia-settings 295.33-0ubuntu1 Tool of configuring the NVIDIA graphics driver ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: libgtk-3-0 3.4.1-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-24.37-generic 3.2.14 Uname: Linux 3.2.0-24-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.0.1-0ubuntu7 Architecture: amd64 Date: Tue May 1 16:47:15 2012 InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120425) ProcEnviron: TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: gtk+3.0 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/992895/+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
