[Bug 889815] Re: hidden 100% cpu usage
okay. swap wasn't working. it is now and i will test the system for some time. also task manager's preferences had 'show all processes' unchecked, so hope some mysterious cpu use will now be indicated. strange how nobody directed me neither to swap (i myself made it bigger sometime ago suspecting memory problems) nor to 'show all processes' despite numerous requests on #ubuntu. 'fresh install' was the usual reply. however, the real 'bug' seems to be why the problem bothers me for a few years already, even though ubuntu was freshly installed at 11.04, as far as i remember, and generally i did up to 10 fresh installs since 2008. there's one trace - 'sudo fdisk -l' states 'partition table entries are in different order than on disk'. but still why ubuntu would install and work for so long without swap (swap partition WAS being prepared during installs) and give no indication of it is beyond me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/889815 Title: hidden 100% cpu usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/889815/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

thanks, no, there is a swap partition, i even made it bigger recently in hope it will help, but it didn't. indeed physical ram is relatively small - 1gb.

this time i encountered near-freeze on firefox, and succeeded to run task manager in an attempt to kill the process that clogs the system - but task manager showed up to 80% cpu use BY the task manager. i tried to get a screengrab, but it didn't work. skinny elephants was the only solution. it seems like a variant of the same problem. ** Attachment added: "syslog" https://bugs.launchpad.net/ubuntu/+bug/889815/+attachment/2655162/+files/syslog -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/889815 Title: hidden 100% cpu usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/889815/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
