See the above thread for details on a bad acpid-CPU throttling problem found in Knoppix and Xandros. With acpi left on, check the scaling_governor mode and also the threshold, and see if the tips at the above link help you any (and of course, report back here). In particular, instead of using the 'performance' setting, you may want to set the threshold to a low value like '20' (worked well for me); A high threshold will kill system responsiveness when the CPU is doing light duty. -- [gutsy] Gutsy performance lags dramatically with ACPI enabled https://bugs.launchpad.net/bugs/138423 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
