This happens to me with the nvidia, the nv, and the nouveau driver. Here's another thing I noticed: when I have the issue, xorg is not able to open the acpid socket:
(WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory) If I log out and log back in, things go back to normal: (II) Open ACPI successful (/var/run/acpid.socket) and cpu usage is normal. -- [karmic] Xorg 100% CPU utilization -- only after first login https://bugs.launchpad.net/bugs/439138 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
