[Ubuntu-x-swat] [Bug 1451117] [NEW] ubuntu 15.04 CPU has one core constantly over 80% usage
Public bug reported: Trying or installing ubuntu 15.04 on MacbookPro 11,2 maintains the first core (out of eight cores) at over 80% its usage even when there are no running applications. This constant CPU usage contributes to heating my laptop. To reproduce, try or install Ubuntu 15.04 on MacbookPro 11,2, and either open the System Monitor application or run `top` from Terminal. I will examine if this issue also affects my office desktop computer. ** Affects: ubuntu Importance: Undecided Status: New ** Attachment added: Screenshot from 2015-05-03 12:58:59.png https://bugs.launchpad.net/bugs/1451117/+attachment/4389782/+files/Screenshot%20from%202015-05-03%2012%3A58%3A59.png ** Package changed: xserver-xorg-input-synaptics (Ubuntu) = ubuntu -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1451117 Title: ubuntu 15.04 CPU has one core constantly over 80% usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1451117/+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
Re: [Ubuntu-x-swat] [Bug 1246215] Re: Ubuntu 13.10, wrong settings for Apple (mouse) touchpad in Macbook 4, 1
Before fixing anything permanently, I think it is important to answer the following questions: 1) What were those values in previous versions of Ubuntu? 2) Why were they changed in the current version? 3) Do current Macbooks work well with such settings? If current Macbooks work well with such settings, it is necessary to find out since what Macbook version the mousepad was changed. I believe it could be since they merged the mouse pad and button together. Based on that, it is possible to change the values based on the Macbook version as Klein mentions using versions less than Macbook x.y. I am very interested in the answer to question (1) because, despite that my mouse works well now, I think its operation was better (smoother) in previous versions, and I still have sometimes odd right-click behaviour.
