But after upgrading to 3.13.0-1, significant lag can be perceived. I downloaded and use the old 3.11 kernel from saucy repo again. Then performance is OK, so it's not the driver's problem. All packages are installed from trusty repo, no PPA is used. And I have never installed or compiled softwares manually. --- ApportVersion: 2.13.1-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: deng 2085 F.... pulseaudio /dev/snd/controlC0: deng 2085 F.... pulseaudio /dev/snd/pcmC0D0p: deng 2085 F...m pulseaudio CurrentDesktop: GNOME DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=28ea490f-0cc7-426b-877c-1d85ac108480 InstallationDate: Installed on 2013-08-02 (161 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Alpha amd64 (20130801) MachineType: Dell Inc.
