It would be easier to reproduce on a bare X. If you do from a vt:
sudo service ligthdm stop sudo Xorg -ac -noreset & sleep 3; DISPLAY=:0 xterm then launch glxgears from the xterm, does it show the behaviour we need to fix? i.e. runs at below refresh rate unless there is another source of interrupts (e.g. wiggling the mouse)? If you can reproduce that, we can begin to test the patches. -- 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/1087582 Title: [gen3] Bad GPU performance whilst CPU is in deep sleep To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1087582/+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
