Mageia forum

Hi,

I have a old computer, but it worked fine until recently.
It's a Athlon 64 3000 + a nvidia 6200 and 1GB of memory.
My mageia is up to date.

When I try to use KDE with the desktop effet enabled, I got some stranges issues :

With proprietary driver :
In open gl mode, I got no background, half of the windows are black, and I have no plasmoids.
Processor is not really happy when desktop effects are enabled

When they are disabled, no issues, everything seems to work.
In xrender mode, I get everything back, but no cube desktop.

With free drivers, performances sucks and I have no cube.

Do you have these issues ?
On an ubuntu forum, they seems to get the same problem because of issues between nvidia driver and kernel 2.6.38. I think we use this one too.
Some people said we could use another backend than xrender or opengl for Kwin. Raster... Do you know how to install it ?

Thanks
Pierre

Shortly available nvidia-current-270.41.19-1.mga1 in nonfree/release.
Maybe worth waiting for and try.

thanks.

I tested kwinhacknvidia rpm, same issue.

I tested also compiz, and this time, KDE is white(in place of black with Kwin).
Will test with the next release.

FWIW, I wouldn't enable desktop effects in KDE for now: http://www.mageia.org/wiki/doku.php?id= ... reezes_kde

I got it this evening and I have still the issue.

It's a lot of frustration to see the ecafe working, and my main computer with a "good" video card without effects.

did you try with a new user account ?

no...
I can remove my .kde folder to test with a new configuration if you want...

I have open gl working nicely(I played eduke32 on this computer yesterday without problem), it's just KDE desktop effects...

i have an issue with desktops effects before , everything broked when i change effect settings. It is nt the same as yours, but it was fixed when i clicked on "default settings" in desktop effects section in system settings.

thanks, I'm gonna try that !!

that doesn't work for me...
Still issues with open gl...

Please test the nvidia-current-275.09.07 that should land in the nonfree/updates_testing repos soon. https://bugs.mageia.org/show_bug.cgi?id=1817

Will do it this evening if I have time. I hope it's in cauldron branche, this computer is still on it.

Usually new packages land in Cauldron before being pushed to stable releases, so yes it's in Cauldron since yesterday.

Tested, works.
Cauldron 64-bit, desktop effects activated, no problems.

I am used to take such things for granted!

Same here all windows are wobbling again;-)
And resizing is working as expected.
My first time of a live experience installing from cooker/cauldron.

You see, there is a first time for everything, not just THAT!

on my side...

I installed the driver this morning.
I saw no changes after rboot.
Desktop effect still work on xrender , but not in opengl mode.

I tried to reset default setting, without effect.

How does it fail with OpenGL?

Hi !

I get black background image on all others desktop.
I can use the cube animation, or the slide one, i get the same result.

A shot in the dark, try enabling direct rendering in the "Advanced" tab in systemsettings -> Desktop Effects.

It was enabled by default, and I disabled it. it seems to works now.

finally, my cpu doesn't like that, it seems to use much more of it(25-80%) with open gl

(FWIW, until I get an i7 CPU, 16/24GB of RAM, I'll just pass the whole idea of using desktop effects if I want to use my box to do other stuff other than enjoying a transparent-panel-with-blur-effect :)).

BTW, I'd try disabling some effects (especially the Blur one), experiment until it stabilises, or just use xrender :)

that's very strange because I have 2 computers.

One laptop with a intal GMA 4500 graphic card and absolutly no problem with desktop effect
One AMD 3000+ with a nvidia geforce 6200 that can't use them... with open gl.

I thought xrender was the one that uses th most the CPU and that open GL was the GPU one...

There any no way to improve it ? nvidia geforce 6200 shhould be able to manage simple effect like that.
