That rules out the obvious causes such as GPU hangs. Is that reproduction script as simple as you can make it? i.e. does just loading firefox and browsing a single website enough to bring the system to its knees, or just totem etc?
Can you please 'apt-get install linux-tools xserver-xorg-core-dbg xserver-xorg-video-intel-dbg libpixman-1-0-dbg' (and probably a host more dbg difficult to tell what's going to be required) and then tell me what is consuming the most time in 'sudo perf top'. Also noting the output of free before/after will be useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1189645 Title: General lag under desktop environments To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1189645/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
