I spent some time looking in to this. In the end it was cured by disabling the ondemand service (which seemed to become enabled when I upgraded to 9.10). It seems that older processors like mine (Opteron 246) don't do ondemand very well and the result is a very sluggish machine.
I the bug can be closed though it might be worth feeding back the fact that the upgrade process (or ondemand) should warn about the potential issues when an older CPU is detected. -- Mouse and Keyboard stuttering/unresponsive - results in some lost key strokes https://bugs.launchpad.net/bugs/480644 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. _______________________________________________ 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
