Sometimes I need to change CPU governors prior to e.g. entering a game, otherwise with ondemand it will behave erratically (frequency changes). This isn't anymore possible under 11.3 RC2 - under systemsettings -> Power Management, I do not see governors when configuring CPU properties under specific profile, it also doesn't work with command line tools:
powersave -f INFO: using SYSTEM upower ERROR: not yet implemented using upower
Same happens if I use powersave as root, the only way to change governor is echoing as root proper value: echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor .. This offcourse limits scripting possibilities, since applications are mostly run as normal user - also changing whole power profile via dbus call (powerdevil) has more benefits, since it can reconfigure other properties and make a more suitable environment for specific needs. CPU: vendor_id : AuthenticAMD cpu family : 15 model : 12 model name : AMD Athlon(tm) 64 Processor 2800+ I've tried to install other vanilla and non-vanilla kernels beside default (compiled from source) and it behaves in same way - so I think it's probably not a kernel fault. After each try, I've read /proc/cpuinfo to see if the frequency did change according to desired governor. Reproducible: Always Steps to Reproduce: 1. Try to change governor with powersave (-f) or powerdevil Actual Results: CPU governor didn't change Expected Results: CPU governor and frequency should change -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
