Description:

KDE Priority handler is an application that monitors the current active processes/applications and let's the user categorize the process into an priority group.

This is very usefull for buggy and/or cpu intensive applications. By adding these to an low priority group makes the desktop usable even if they go berserk on the system.

Hope you find it usefull.

How it works:

By default most user processes get the nice level 0, higest possible to set without root access.
My program monitors the active processes and change thire nice level to correspondent with the group it's been added to witin my program.

ex. The user starts konqueror, and get an popup about this processes is found and is unrated. Now the user chooses "konqueror" in the treeview to the left, then presses the "Webbrowser" icon.
This renices konqueror to the nice level of webbrowsers. Next time konqueror is started (and KDE Priority handler is runing) it will automaticly renice the process without any user interferance.

With the introduction of v0.2 most of the suggested features are added and quite a few other. Please feel free to comment/drop me an mail about features you miss or bugs you found.




Changelog:

Fix: It now works with kernel 2.6.23, as well as with prior kernels.

2007-10-28
I just upgraded to kernel 2.6.23, and it looks like theer might have been some changes to the /proc layout due to the new shedulers. So right now this app wont work for .23.

The issue with ionice is that it requires root access. I'll try to figure out a nice way to do this for the 2.0 release.

Not realy, as most users have different preferenses. I myself like to have the music players at nice 1, the kde background processes at nice 10 then i/o at nice 11 and webbrowser at 15 then Trash/Buggy at 20. And inbetween I put groups for apps depending on how important i think they are compared to the others.

Try:
./configure
make
then as root:
make install

It works on both 32bit and 64bit for me.

Great to hear, dnt hessitate to give inputs and report issues.. I havent got a single bugreport since the beta, thought i havent encountered a bug myself since RC2 (iv had it running 24/7 since it's release).
And only feature request is to add ionice support wich im putting up till the KDE 4 release.

So either all users are happy with it as it is now, or noone is using it :D

 Dependencies Problems

 
 by geekyone on: Oct 22 2008

Is this project still under development?

The idea sounds like exactly what I need right now. I have had a number of systems fail on me in the last few months and as a result am currently using on an old 1.4Ghz AMD Athlon with 512MB RAM running CentOS 5.2, until I can get a new one. Due to the slow system I'm currently on I've had some problems with music freezing for a few seconds when I attempt to do operations that I would normally consider to not be very high load. Even launching an application at times may cause it to freeze, even if just for a split second. Needless to say, it's annoying since I like to listen to music while doing development.
I was trying to find a program to manage priority levels of applications, to keep my music from freezing on me, when I found yours. I immediately realized it would also limit problems resulting from a resource hog such as the Flash Firefox plug-in, and allow me to continue to work without ending the process immediately.

If your program is as good as it sounds, and I can get it working, I likely will continue to use it in the future as I am a huge multi-tasker and have never met a system I couldn't lag out within a few days.

When attempting to compile after resolving multiple dependency issues, I get the following error message:

checking for Qt... configure: error: Qt (>= Qt 3.2 and < 4.0) (headers and libraries) not found. Please check your installation!
For more details about this problem, look at the end of config.log.

I installed the following while trying to resolve dependencies, but I guess they aren't what your application is looking for.
qt - 1:3.3.6-23.el5.i386
qt-devel - 1:3.3.6-23.el5.i386
qt4 - 4.2.1-1.i386
qt4-devel - 4.2.1-1.i386

I suppose I could try to find an older version of one of those if you tell me which it's looking for, but kinda afraid it won't work with how new my OS is.

That seems very strange if you have qt3.3.6 it should work, you can try to edit the make file and force it to look for 3.3.6.

On my spare time I am working on an newer version of this application, it's now splitted into an daemon part and an client.

An with the first release it will contain an kde4 plasmoid an an cli client. But it's still under development and unfortunally it's going slow due to lack of time/money on my side.

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
