Re: [Announce] QCPUFreq - save battery power by adjusting your maximum CPU speed
 

That's true. I tried another QT app (I think), Fast App Manager, and found the same behavior so I guess that's the way it is.
The hildon-status-menu patch I mentioned is this one:
http://talk.maemo.org/showthread.php?t=66586

To me, the warning message would work since in normal case users don't adjust cpu frequency, frequently.

However, I would prefer an option in setting because the UI flow is cleaner. I would suggest calling it "Frequency Limiter" to highlight the purpose of such option. Then you can do either of the following to display the limiter status:

1) Full info on main UI:
Minimum CPU speed: 500MHz
Maximum CPU speed: 600MHz
Frequency limiter: ON, 700MHz max

If user accidentally slide past the limiter setting, display a notification and ignore the change.

2) On/Off info on main UI:
Minimum CPU speed: 500MHz
Maximum CPU speed: 600MHz (Limiter: ON)

and make slider scales to the limiter setting so there's no way to slide past the limiting frequency.

Re: [Announce] QCPUFreq - save battery power by adjusting your maximum CPU speed
 

I just implemented voltage profile loading in QCPUFreq 0.4.2 (in extras-devel). Please test and report back.

I am still thinking about that. I still believe that it clutters the UI. Right now I am considering a setting: "Confirm frequency before applying" - if this option is set QCPUFreq will always show a dialog for confirming the frequency before actually applying it.
The benefits of this approach are:

• the main UI does not need to change at all
• only one simple yes/no setting (probably easier to understand)

It works great, thanks!

Just do whatever you feel more comfortable with. For me, it's easier to speak than to code!

Re: [Announce] QCPUFreq - save battery power by adjusting your maximum CPU speed
 

excellent app! works great with the load profiles!

Re: [Announce] QCPUFreq - save battery power by adjusting your maximum CPU speed
 

load profiles is when i OC using xterm and save my profile ? if thats so i think if QCPUFreq can change min. value besdie max. it could replace that option, or am i missing something ?

Re: [Announce] QCPUFreq - save battery power by adjusting your maximum CPU speed
 

Thanks for implementing profiles loading.

One good extra feature would be if it would show on the main screen what profile is currently loaded. I know it can be difficult to "know" just by running "kernel-config show" because you should compare to the preset files, but maybe just remember what preset was loaded from QCPUFreq last time.

I was going to ask also support at least two custom settings, but of course I can edit the default preset-files to fit my own needs.
I basically just want two profiles; for normal power use and for maximum battery saving use. For latter I can use ULV or XVL and not overclock, but for former I want to overclock so I cannot have lower voltages than VL-profile.

Re: [Announce] QCPUFreq - save battery power by adjusting your maximum CPU speed
 

May I ask you if your intentions haven't changed since then? I wish I could chance my settings to 500-600 for instance, and it would be "faster" with a GUI... and there isn't even the necessity to put a second scrollbar, just another slider in the same scrollbar and then you could add three things with just one thing:
1)Would add the ability to change the lowest frequencies to the ones that don't care about battery, but to how "snappy" their n900 are;
2)Would prevent, with two sliders in the same scrollbar, that you could make the lower frequency be higher than the higher frequency (in fact it would make the lower frequency be forever lower than);
3)Would not change the UI too much, or add too much complexity. Two sliders in the same scrollbar. Minimum and maximum frequencies, and one will never go higher than the other.

I wish I could have that |:), something like that I can have only with an "underground" fork of CPUfreqUI |:/

Re: [Announce] QCPUFreq - save battery power by adjusting your maximum CPU speed
 

That's the thing - there is no such widget which combines two QSliders on one single QScrollbar.

For a snappy N900 experience you could create a custom preset with kernel-config (with min/max at 550/700) and load it with QCPUFreq.

Re: [Announce] QCPUFreq - save battery power by adjusting your maximum CPU speed
 

OOOw, this is a bummer. I don't have Qt programing experience yet, but I can say that when I had to do a different widget in delphi, it was painful, so I can see why you won't even think of trying (and I don't condemn you for that).

Anyway, thank you |:)

Best way to use at maximum frequency with maximum battery time is to drag the bar to 1150mhz and turn off your phone. :p
