Hi, In order to help with this bug, we need some more information about your system. What graphics card are you using? Can you attach the output of the 'lspci' and 'glxinfo' commands, as well as the files /etc/X11/xorg.conf and /var/log/Xorg.0.log?
In addition, you could try following the advice at https://wiki.ubuntu.com/X/Troubleshooting/HighCPU and let us know the results. In the future, if you report bugs like this using the command 'ubuntu- bug xorg', it will automatically attach the relevant information. ** Changed in: ubuntu Status: New => Incomplete ** Package changed: ubuntu => xorg (Ubuntu) -- X uses CPU constantly https://bugs.launchpad.net/bugs/436178 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
