I had the same problem after upgrading to Ubuntu intrepid yesterday. Xorg taking 40-70% of CPU and the fan going crazy.
I solved this by re-generating an /etc/X11/xorg.conf with sudo dpkg-reconfigure -phigh xserver-xorg My old xorg.conf was configured to work with DUAL screen see my conf here: http://21croissants.blogspot.com/2008/10/ubuntu-804 -xorgconf-for-samsung.html I guess I'll have to reconfigure xorg when I plug the dual screen again or maybe intrepid will detect it automatically. -- xorg 10-20% cpu usage after intrepid upgrade, general system sluggishness https://bugs.launchpad.net/bugs/294972 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
