[SOLVED] Any tricks to make kde 4.3 faster

Anisha Kaul · 04-19-2010, 12:25 AM

I have already disabled desktop effects, can I do something else to make Kde 4.3 faster ?

Kindly guide !

catkin · 04-19-2010, 12:43 AM

Change to Xfce or Lxde?

Anisha Kaul · 04-19-2010, 12:47 AM

Can't do that, using Kde 4.3 for the latest Marble !

Kindly guide !

What do you think we can "kindly guide" you with? You don't say anything about the hardware you're trying to run this on, or what the problem really is, or what your needs are.

Saying "make it faster" is pointless...you may want 300 frames per second at 2560x2048x32bpp, out of a netbook, and that isn't going to happen. Then again, you might have the latest nVidia monster card, and don't have the drivers right. Provide details and a good question, and we might be able to help.

Then I'm sorry for taking your thread off the zero reply list

I hope this bump brings some useful replies.

Marble won't work under another desktop environment?

I think, Marble is all KDE 4 , Qt 4 ... ( Kde-Edu )

No need to feel sorry about anything. I should have mentioned the marble necessity earlier.

Marble needs Kde 4.3 because it is Kde-Marble not Qt-Marble.

I remember myself replying like this to a noob, who didn't provide enough details in his question.

I didn't realise this has something to do with the hardware, that's why didn't mention it. (I have now mentioned the hardware specifications in my next post).

I actually wanted to remove everything that was making kde slower in responding as compared to xfce.

If my question still doesn't make sense, kindly let me know.

That's a tall order! You would have to get the KDE source, reverse engineer it (seriously non-trivial!) until you understood it well enough to excise the bulk of it (maybe not even possible because of cross-dependencies). Impracticably difficult (?) and then you'd have to start over when a new release of KDE appears.

Easier to remove the KDE dependencies from Kde-Marble?

I thought i could uncheck all the memory hogging softwares from yast and get a faster KDE ! Is'nt that possible somehow ?

That would speed KDE start up but would not speed its performance after that significantly unless the system is so short of memory that is is swapping.

MTK358 · 04-20-2010, 06:40 AM

KDE4 (what a horrible train wreck IMO) has a lot of things that it *must* have to run that are very resource-hogging, such as Plasma. So AFAIK it's not possible to make KDE4 fast.

But does KDE Marble just use KDE libraries, or does it somehow integrate with KDE and interacts with Plasma or whatever?

Because every KDE app I've ever seen works wonderful on non-KDE desktops.

Anisha Kaul · 04-20-2010, 07:03 AM

MTK358
Thanks for bothering!

All I could find is kde-marble uses a variety of KDE libraries and also libplasma.so, I don't know if that is related to the plasma you are talking !

catkin
Thanks for the input ..

You mean I should install KDE for marble and some other DE for my use and then use marble from the other DE ?
