Can you describe what you mean by lagging? Does the mouse move fluidly? Is the keyboard and mouse clicks quick? Is it redrawing of applications that slows?

[Ubuntu-x-swat] [Bug 1188874] Re: [gm45] Environment lagging randomly
Well, I rally tried to identify the cause of this problem but with no success. There isn't a pattern. Anyway, I'm almost sure that is the video driver because of the following: one thing I forgot to mention is that, as a workaround, when the system is lagging I press the Super button to open the dash and the system stop lagging. It seems that it is a composite/driver/3D issue. Using other desktop environment like Enlightenment (with composite enabled) does the same lagging - so it is not related with unity.

[Ubuntu-x-swat] [Bug 1188874] Re: [gm45] Environment lagging randomly
That command disables the kernel polling for new outputs, it should be using hardware interrupts anyway. Another thing you can try is whether change cpufreq scaling governor makes a difference, in particular using performance. For instance, the memory clocks are driven by the CPU clock so as cpufreq slows the CPU down, the GPU becomes starved. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1188874 Title: [gm45] Environment lagging randomly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1188874/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
