aiglx problem

[Ibanez]

I've been working on this problem for a couple of days. I have an nVidia 6800 display card running with great with a dual monitor setup. I'm running the latest driver from nVidia's website (Version: 1.0-9755 released 3/7/2007). This is all on Core 6.

Everything works fine in certain video modes. For instance, if I'm in single monitor mode everything runs fine. If I configure the display to run in twin view (one desktop stretched across two monitors) that works as well. But when I try to setup my desktop as an extended view (seperate x screen) with xinerama enabled I'm not able to turn on desktop effects.

I've searched quit a bit for a solution in forums and on google and haven't found an answer. Is this even possible? Any help would be appretiated. Thanks.

I have the same problem. I tried running it from the console. The following errors are printed:

compiz: No GLXFBConfig for default depth, this isn't going to work.
compiz: Failed to manage screen: 0
compiz: No manageable screens found on display :0.0

If I run beryl I get the following result:

************************************************** ************
* Beryl system compatiblity check *
************************************************** ************

Detected xserver : NVIDIA

Checking Display :0.0 ...

Checking for XComposite extension : passed (v0.3)

Checking for GLX_EXT_texture_from_pixmap : passed
Checking for non power of two texture support : passed
Checking maximum texture size : failed

Root window size (3200/1200) is bigger then maximum texture size (2048x2048)

X Error of failed request: GLXBadContext
Major opcode of failed request: 144 (GLX)
Minor opcode of failed request: 4 (X_GLXDestroyContext)

So apparently my hardware is just not good enough (it is a GeForce 6800 with 128 MBs)

I too am suffering this problem. I can run desktop effects with one monitor perfectly, but when I try to run desktop effects with two monitors, I cant get the "eye candy" to work spanning across both monitors.

I am of the "opinion" that AIGLX dosn't support desktop effects across a dual monitor setup yet? Is this correct?

Any takers?

I think it is a matter of your videocard not being able to handle the high resolution. See my previous post:
