I found out how to change the frequency. Disocovered the package 'cpufrequtils', which contains 'cpufreq-info' and 'cpufreq-set'. Plus the files dealing with this, I learned, are located in: "/sys/devices/system/cpu/cpu0/cpufreq/" I still haven't learned why the frequency was set at its minimum during boot time. If anyone has a clue, please share. This is a laptop and I checked the powersave settings and there was nothing odd. CPU clock should scale down when the laptop is unplugged, but it's been plugged in the whole time. But the system sure is a lot more responsive since I upped the clock to its maximum. That is nice. I was getting a lot of lag when switching between windows and/or desktops. That's gone now. It's now a very smoth transition. -- Sean Burns [EMAIL PROTECTED] http://bworks.dyndns.org/ [EMAIL PROTECTED] http://cowl.freeshell.org/ SDF Public Access UNIX System http://sdf.lonestar.org/ _______________________________________________ CWE-LUG mailing list [email protected] http://www.cwelug.org/ http://www.cwelug.org/archives/ http://www.cwelug.org/mailinglist/
