I believe I am running into this same problem. Sporadically the computer stops responding for around 2-3 seconds. I am running 10.04 amd64 on a Macbook 4,1.
Currently subscribing via Launchpad is broken, I get an error, so I cannot submit an apport report, but included are my Xorg and lspci logs. ** Attachment added: "Xorg.0.log" http://launchpadlibrarian.net/47960680/Xorg.0.log -- 64bit Ubuntu 10.04 Stops Responding https://bugs.launchpad.net/bugs/574152 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
