[Ubuntu-x-swat] [Bug 1309919] Re: Xorg causing 100% cpu load
Just a note that I am seeing this problem as well, here on an AMD 8350 8-core system using Trusty 14.04 AMD64. The Xorg process takes about 20%-35% of one core, when the system is otherwise idle. I'm open to suggestions regarding how I can dig deeper to determine the cause, because obviously killing the Xorg process isn't an option (or I wouldn't be running it in the first place). As an experiment, to see if it would help to restart X, I did try killing the process then logging back in with the new Xorg process, but the CPU usage was the same as it was before. Any suggestions are welcome, and I am willing to help debug this.

Bug report was withdrawn by the original user, and over here it was a driver issue, so I am marking this ticket invalid. ** Changed in: xorg (Ubuntu) Status: Confirmed = Invalid -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1309919 Title: Xorg causing 100% cpu load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1309919/+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
[Ubuntu-x-swat] [Bug 1309919] Re: Xorg causing 100% cpu load
** Description changed: + EDIT3: I'll withdraw this bug report. + Primary problem here was the combination of xfce-compositor with an slow graphics card (mga). + Disabling the compositor setting in xfce did it for me. Disabling showing window content on resize+move makes things faster on this graphics card, too. + EDIT2: it seems that even the cpu graph in the top bar produces enough load to get Xorg with Matrox G450 (PCI) busy. Without cpu graph responsiveness is still far slower than with 13.10. EDIT: after deleting almost every file+directory which starts with . in my home directory, this problem has vanished, but overall performance seems slower than with 13.10. Kind regards, Jochen Dear reader, after upgrading from 13.10 to 14.04 (xubuntu, amd64), Xorg uses 100%, overall reaction is slow and mouse pointer is flickering.
