Please be gentle - I'm new here! (Mandriva 2009.1 install with an nVidia GeForce 4 4600 Ti; dual monitors: 1 VGA & 1 DVI)

Prior to getting nVidia's TwinView to work (which unfortunately took some tweaking) I had desktop effects working great - wobbly windows, minimize animations, fade in and out for various things, etc... But once I got TwinView working, all of the effects stopped working. So I went back into "Configure your desktop" and double-clicked "Desktop" in the "Look & Feel" section. Here, if I enable desktop effects and click Apply, I get the following error:

Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values.
Check your X configuration. You may also consider changing advanced options, especially changing the compositing type.

Now, like I said - I'm new here - but please understand that I've tried everything I can find on Google, but none of them seem to mention that the effects work fine when I'm only using one monitor. I've tried XRender, checking the "Disable functionality checks", enabling "Smooth Scaling", ensuring that "Enable direct rendering" is checked, changing the Texture Filter to Bilinear and everything else I could get my hands on. It always spits out the error message.

I also tried downloading the most recent PREVIOUS driver for the card, but the nVidia setup gave me a slew of errors about not being able to compile for my kernel or whatever.

I'm running the most current nVidia driver for this card at the time (96.43.11) and I know that the card works everywhere else - for example, Extreme TuxRacer looks amazing with all the shimmering and what-not.

Help? Anything?

Can you post the output of glxinfo please, I'm curious how you managed to have compositing working in the first place with such an old driver as KWin forces compositing to be disabled with anything older than the 173 series.

I have absolutely no idea what any of this madness is, and I don't know if this is what you're asking for... but here goes:

Sorry - I just read your entire post... I can't tell you WHY, but for the GeForce 4600 Ti that I have, nVidia is using a slightly different numbering scheme, and the driver that I currently have installed (96.43.11) is dated somewhere around April of this year - so it's current...

Anybody?

How about a list of known compatible cards? I can't seem to find one of those, either...

For what it's worth - I can enable Metisse, and then startx from the console login as root and I get a kwin error, but things obviously look completely different - I can change the geometry of the windows and they go transparent when I drag them... Once I *reboot*, however, X never really starts... It starts, shows me the desktop and an error about kwin and then logs me out immediately.

While Metisse was enabled, if I went to enable desktop effects it tells me bluntly that compositing is not supported on my system...

So I reverted everything back to my working, non-effects settings so that I can use it. That's where I'm at now, but seriously this shouldn't be so difficult... Should it?

171 views (currently) and I feel like I'm talking to myself. I would much rather a bunch of people saying "...that sounds really weird - because I have the same hardware and don't have that problem..." or maybe "...that shouldn't happen - try completely reinstalling the drivers for your video card..."

I ditched KDE altogether. I'm now using Xubuntu with dual monitors, TwinView, and all effects working great. I'm using the same exact driver version.

Ok, so I'm back to KDE - this time with Kubuntu. There's just too many things that Xfce doesn't do right out-of-the-box. ...And now I have more information on this scenario:

When I install the nVidia driver for my system right off the bat, it tells me that I need to restart in order to use the driver. So I restart. After that restart, if I enable desktop effects I can use them and they work GREAT. Wobbly, transparency, fading, yadda yadda yadda with no issues.

BUT if I reboot my computer, all of the effects are completely gone. Going to desktop settings tells me that they're still enabled, but they're clearly not working. So I uncheck the box and re-check it. When I click the "Save" button I get the same error message telling me that "Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values. Check your X configuration. You may also consider changing advanced options, especially changing the compositing type."

Once I got this message, I completely reinstalled Kubuntu from scratch again and duplicated the same scenario.

What the heck!?! It was just working!! What does a reboot do that is causing issues here? Somebody PLEASE answer and help me out here!

When compositing is working can you do a glxinfo? If the "OpenGL version string" is the same as the one above then don't bother posting it again. As I mentioned above KWin doesn't even support your graphics card and automatically disables itself--why it's actually "working" is beyond me. This might actually be the reason KWin does the version <173 check as I've been repeatedly given the reason that "Older nVidia drivers do not reliably support compositing".

Can you also try Compiz?

I actually didn't know that Compiz was an option under KDE... But I've gone with the mainstream and installed Ubuntu now and I can tell you that there was a similar issue - upon enabling the proper driver and desktop effects (the medium setting) everything worked awesome, and then after a reboot all of the menu bars disappeared. This was resolved by the following:

sudo nvidia-xconfig --add-argb-glx-visuals -d 24

...I don't know if that command from the terminal will do anything to resolve the KDE issue - whaddya think? Is it worth a try or does the above command only work in Ubuntu?

Try it if you wish.

Compiz will run fine under KDE, there's even a setting in System Settings -> Default Applications -> Window Manager for it to load instead of KWin.
